4IR Technologies to Boost Competitiveness of Africa’s Mining Industry – Energy Capital & Power

September 25, 2023 | Author: admin

Set to define the future of mining, real-time data analytics provide additional insights into underlying mining systems and enable short interval control approaches for decision-making. Mining-specific solutions include tracking loads of materials being transported from mines, wear rates on critical mining tools to enable predictive maintenance, and computer vision applications, which all contribute towards developing a robust data engineering process and limiting the complexity of data management and warehousing.

In South Africa a leading producer of platinum, chrome, gold and diamonds globally ICT provider BCX has deployed 5G wireless-enabled technology to the Nungu Mine, enabling video monitoring and integrated connectivity to enhance the mines operational efficiencies and safety.

With evolving Environmental, Social, and Governance (ESG) standards, rising energy costs and limited infrastructure, mining firms operating in Africa are being compelled to innovate to improve efficiency and cut costs. Technologies such as AI and predictive analytics create actionable insights from raw data and offer the potential to reduce unplanned downtime, streamline processes, improve asset performance, and achieve more reliable and predictable outcomes for mining throughputs.

For example, ICT company Minetec Smart Mining has implemented collision avoidance devices across its operations in South Africa, with a view to reducing risk exposure and fatalities around mining operations.

Additionally, predictive analytic solutions and deep learning approaches can help diagnose equipment issues before failure and forecast an assets remaining lifetime. This technology is poised to enable mining companies to optimize maintenance schedules, thus allowing users to mitigate potential failures and maximize operational strategies.

Mining companies operating in Africa have already begun to embrace digitalization and 4IR technologies, taking advantage of the full spectrum of live metrics and data analytics to minimize their consumption of limited resources, reduce waste, improve transparency and ensure compliance.

In Mali, the Syama Underground Gold Mine developed by the Socit des Mines de Syama installed fiber-optic network connections to better manage and monitor mining activities. The Syama Mine is the worlds first purpose-built automated mine and has served to reduce costs by approximately 30% while improving overall efficiency. Meanwhile, in December 2021, diamond mining producer Debswana inaugurated its first 5G-oriented smart mine at the Jwaneng open-pit diamond mine in Botswana. The network solution provides stable connectivity while enabling interconnection among the mines production, safety and security systems.

Data analytics and predictive maintenance in mining is expected to reduce the planning time of operations by 20%-50%, while reducing overall operational costs by roughly 10%. Mining companies in Africa that embrace digitalization can save millions of dollars in averted asset failures, while improving consistency, performance and reliability. Meanwhile, the adoption of renewable energy systems can help the African mining sector reduce its environmental impact, with autonomous 4IR technologies poised to cut fuel consumption in processes such as loading, crushing and drilling.

Some of the continents most recent mines, such as the Kamoa-Kakula Copper Complex operated by diversified mining company, Ivanhoe Mines are being designed with automated equipment, allowing operators to work remotely, or semi-remotely, thereby vastly improving safety for miners.

The economic and environmental benefits of digitalization in the African mining sector will allow active mines to become more profitable and productive, while contributing to the reskilling of the local workforce through digital skills and training programs. Critical for the production of renewable energy technologies, such as solar panels, wind turbines, and electric vehicle batteries, the continent produces approximately 80% of the worlds platinum, 70% of global cobalt, 50% of its manganese, and a substantial amount of chromium, in addition to other critical resources such as copper, lithium, and rare earth elements.

Embracing available and future 4IR technologies will be imperative for the resilience and sustainability of the African mining industry, allowing the continent to drive ESG performance standards while ensuring its extractive sector remains competitive on the global stage.

Metal-mining pollution impacts 23 million people worldwide – BBC

September 25, 2023 | Author: admin

Updated 22 September 2023

At least 23 million people around the world live on flood-plains contaminated by potentially harmful concentrations of toxic waste from metal-mining activity, according to a study.

UK scientists mapped the world's 22,609 active and 159,735 abandoned metal mines and calculated the extent of pollution from them.

Chemicals can leach from mining operations into soil and waterways.

The researchers say future mines have to be planned "very carefully".

This is particularly critical as the demand surges for metals that will support battery technology and electrification, including lithium and copper, says Prof Mark Macklin from the University of Lincoln, who led the research.

"We've known about this for a long time," he told BBC News. "What's alarming for me is the legacy - [pollution from abandoned mines] is still affecting millions of people."

The findings, published in the journal Science, build on the team's previous studies of exactly how pollution from mining activity moves and accumulates in the environment.

The scientists compiled data on mining activity around the world, which was published by governments, mining companies and organisations like the US Geological Survey. This included the location of each mine, what metal it was extracting and whether it was active or abandoned.

Prof Macklin explained that the majority of metals from metal mining is bound up in sediment in the ground. "It's this material - eroded from mine waste tips, or in contaminated soil - that ends up in river channels or [can be] deposited over a flood-plain."

Prof Macklin and his colleagues used previously published field and laboratory analyses to work out how far this metal-contaminated sediment moves down river systems.

That data allowed the scientists to produce a computer model that could calculate the extent of river channels and flood-plains around the world that are polluted by mining waste - both from current and historical mining activity.

"We mapped the area that's likely to be affected, which, when you combine that with population data, shows that 23 million people in the world are living on ground that would be considered 'contaminated'," said Chris Thomas, who is professor of water and planetary health at the University of Lincoln.

"Whether those people will be affected by that contamination, we simply can't tell with this research, and there are many ways that people may be exposed," he stressed. "But there is agriculture and irrigation in many of those areas."

Crops grown on contaminated soils, or irrigated by water contaminated by mine waste, have been shown to contain high concentrations of metals.

"Animals grazing on flood-plains may also eat contaminated plant material and sediment, especially after flooding, when fresh metal-rich sediment is deposited," the scientists explained in their paper.

"With climate change and more frequent floods," Prof Macklin added, "this legacy [pollution] is going to extend and expand."

Prof Jamie Woodward from the University of Manchester, who was not involved in the study, said the research highlighted the threat posed by "silent pollution" stored in flood-plains.

"A good deal of river monitoring is focused on water when the real 'nasties' are often associated with river sediments," he told BBC News.

"We need to better understand how contaminants are transported in the environment and where they are stored. This allows us to assess hazards and to mitigate against them. Heavily contaminated flood-plain grasslands should not be used for livestock grazing, for example."

The researchers point out in their study that metal mining represents "humankind's earliest and most persistent form of environmental contamination". Waste from mining began to contaminate river systems as early as 7,000 years ago.

Elucidating disease-associated mechanisms triggered by pollutants … – Physician’s Weekly

September 25, 2023 | Author: admin

Despite well-documented effects on human health, the action modes of environmental pollutants are incompletely understood. Although transcriptome-based approaches are widely used to predict associations between chemicals and disorders, the molecular cues regulating pollutant-derived gene expression changes remain unclear. Therefore, we developed a data-mining approach, termed DAR-ChIPEA, to identify transcription factors (TFs) playing pivotal roles in the action modes of pollutants.Large-scale public ChIP-Seq data (human, n=15,155; mouse, n=13,156) were used to predict TFs that are enriched in the pollutant-induced differentially accessible genomic regions (DARs) obtained from epigenome analyses (ATAC-Seq). The resultant pollutant-TF matrices were then cross-referenced to a repository of TF-disorder associations to account for pollutant modes of action. We subsequently evaluated the performance of the proposed method using a chemical perturbation data set to compare the outputs of the DAR-ChIPEA and our previously developed differentially expressed gene (DEG)-ChIPEA methods using pollutant-induced DEGs as input. We then adopted the proposed method to predict disease-associated mechanisms triggered by pollutants.The proposed approach outperformed other methods using the area under the receiver operating characteristic curve score. The mean score of the proposed DAR-ChIPEA was significantly higher than that of our previously described DEG-ChIPEA (0.7287 vs. 0.7060; Q=5.27810; two-tailed Wilcoxon rank-sum test). The proposed approach further predicted TF-driven modes of action upon pollutant exposure, indicating that (1) TFs regulating Th1/2 cell homeostasis are integral in the pathophysiology of tributyltin-induced allergic disorders; (2) fine particulates (PM) inhibit the binding of C/EBPs, Rela, and Spi1 to the genome, thereby perturbing normal blood cell differentiation and leading to immune dysfunction; and (3) lead induces fatty liver by disrupting the normal regulation of lipid metabolism by altering hepatic circadian rhythms.Highlighting genome-wide chromatin change upon pollutant exposure to elucidate the epigenetic landscape of pollutant responses outperformed our previously described method that focuses on gene-adjacent domains only. Our approach has the potential to reveal pivotal TFs that mediate deleterious effects of pollutants, thereby facilitating the development of strategies to mitigate damage from environmental pollution. 2023.

Interventions against illegal mining have a spillover effect on legal … – MINING.com

September 25, 2023 | Author: admin

Back in 2019, the Peruvian government deployed Operation Mercury (Operation Mercurio) in the La Pampa region, an area where gold mining is banned in most places. La Pampa straddles the Interoceanic Highway. North of the highway, mining is mostly legal in mining concessions. However, south of the highway mining is strictly prohibited in the buffer zone of the Tambopata National Reserve.

Through Operation Mercury, armed military and national police were dispatched to the region and had a sustained presence until March 2020. Miners were evicted and mining equipment was destroyed. The intervention successfully stopped illegal gold mining activity in La Pampa but activity in legal areas spiked, triggering many of the same environmental concerns.

Although illegal gold mining operations in La Pampa came to a near halt during Operation Mercurys two intervening years (20192020), mining activity essentially just shifted across the road to legal areas on the other side of the Interoceanic Highway, Dethier said.

Following Operation Mercury, mining decreased by 70% to 90%. Excavated mining pits in illegal mining areas decreased by up to 5% per year as compared to increasing by 33% to 90% per year before the intervention.

Although deforested areas experienced revegetation at a rate of 1 to 3 square kilometres per year, progress was offset by increases in deforestation in legal mining areas north of the Interoceanic Highway at a rate of 3 to 5 square kilometres per year. Most of the revegetation occurred on the edges of deforested areas, with the highest revegetation in La Pampa south. Mining pond areas outside intervention zones also saw increases ranging from 42% to 83%.

To assess Operation Mercurys impact on mining activity, the research team drew on satellite data from 2016 to 2021 from the European Space Agencys Sentinel-1 and Sentinel-2. Data were obtained from nine mining areas: four illegal mining areas targeted by the intervention, two legal areas to the north on the other side of the Interoceanic Highway, and three distant sites that were not part of the enforcement, which served as a control for the study.

Using the radar and multispectral data, the researchers were able to quantify changes in water, water quality, mining pond areas, and deforestation in La Pampa following Operation Mercury, by comparing data from before, during, and after the intervention.

As part of the analysis, the team examined the spectral properties of the mining ponds and changes in pond colour.

Mining ponds typically take on a yellow colour, which acts as a marker for gold mining activity. The yellowness of the ponds is associated with increases in suspended sediment in the water.

Through gold mining processes, sediment is churned up from the land, creating turbid water with lower reflectance levels, while clearer water has higher reflectance. After Operation Mercury was implemented, reflectance increased in mining ponds in La Pampa south but then stabilized.

Following Operation Mercury, pond yellowness decreased rapidly after mining activity was suspended in all areas of La Pampa, except in the north. In La Pampa northwest, mining activity spiked and pond yellowness increased by 43%, as compared to before the intervention. In La Pampa northeast, yellowness remained stable due to continued mining activity

Like many other countries around the world with highly prized natural resources, with Perus rich deposits of gold, it has had to determine who controls this extractable resource and how this particular mining sector will be formed, David A. Lutz, co-author of the paper that presents these findings, said.

By January 2023, when the paper was under review by the journal, illegal gold mining had resumed in protected areas, as enforcement and anticorruption activities by the military and national police had ceased, as they were redeployed to focus on the covid-19 pandemic.

Our results demonstrate how intervention at the federal level can effectively stop illegal mining in Peru, Dethier said. But that is just one aspect of the problem, as a multifaceted approach is necessary to address the long-term impacts of both illegal and legal gold mining activity on humans, wildlife and the environment in the Madre de Dios watershed.

In the researchers view, strong governance and conservation and remediation strategies are needed to protect this tropical biodiversity hotspot.

Dethier also mentioned that the same applies to protected areas in other counties, as another study he and Lutz co-authored showed the rise of similar mining operations in 49 countries across the global tropics.

Goldman Sachs has forecast "healthy" growth in new lending at three major Indian banks over the next six months, which could lead to a significant upside for those stocks.

The Wall Street bank said Indian bank stocks have underperformed over the past three to six months despite a positive outlook for lending growth in the sector.

It named three lenders, that are expected to outperform the sector over the next 12 months, as "Top Buys".

Portfolio manager Kamil Dimmich of North of South Capital says the word on the ground is that stocks in technology firm Nvidia are cheap even as he may personally not think so.

Shares in Nvidia tripled this year as the company's market valued topped $1 trillion over the optimism surrounding its artificial intelligence-powered applications.

Dimmich, who manages the $1.5 billion Pacific North of South Emerging Market All Cap Equity fund, says he is "always looking for great companies with strong cashflows that are not correctly reflected in the market." His focus is identifying undervalued stocks in emerging markets.

What is his list of 'great value' companies to watch?

A digitalisation platform with an edge – Australian Mining

September 25, 2023 | Author: admin

Improved decision-making is a primary benefit of digitalisation and this comes from having access to qualified data.

However, businesses are still looking to solve the problem of how that data is collected and processed so that it becomes informative and useful especially when there are large volumes of it.

According to Freddie Coertze, national IoT manager for ifm Australia, this is why the moneo digital solution can act as a middleware with an edge layer.

When we say middleware, were talking about a software layer that facilitates communication and integration between different applications, devices and systems, Coertze said.

And when we talk about edge computing in the context of collecting data and Internet of Things (IoT), were talking about processing large amounts of data near to where it is collected, which means its not clogging up networks or interfering with latency. Our digital solution, moneo, offers this it can serve as a middleware with a soft edge.

We have a large mining client who use our sensors to collect raw data, but they dont want to push that raw data directly into their higher level maintenance platform, as it would use up a lot of space and take them a lot of time to qualify that information.

With moneo, which has an in-built data science tool, it has the ability to filter the data, and with applied analytics on the edge, translates this data into readable and actionable information. Then it is sent to that upper platform. So in that context, moneo is acting as a middleware on the edge.

Its just more efficient, Coertze said. Edge computing helps businesses optimise operations by processing data near to the source rather than continuously sending it to a platform in the cloud.

It also adds a security layer which is important when we consider that most factory operations and automation systems havent been exposed to external threats before the event of digitalisation.

ifms moneo edgeConnect communication interface software can turn any PC into an edge device.

Basically this is a software component that will load onto a PC so it empowers you to make any PC an edge device. You could put these in several points around your facility or plant, Coertze said. It can qualify data near the source and send the results to the top platform.

In fact, moneo edgeConnect is designed to facilitate interoperability by building a bridge between production and automation systems (OT) with internal information systems and cloud platforms (IT).

This is a big deal for businesses, because it gives visibility across the whole operation from the shop floor to the top floor, Coertze said.

Importantly, moneo enables outgoing data transfer to the cloud platforms Amazon AWS and Microsoft Azure as well as third-part systems via an MQTT or OPC-UA server.
