Sep 02, 2020nbsp018332While the COVID-19 pandemic has caused unprecedented financial disarray on a global scale, there is a silver lining for some commodities mined in the Democratic Republic of Congo DRC. This is the consensus of panellists on a recent DRC Mining Week DMW webinar. GERARD PETER reports. This article first appeared in Mining Review Africa Issue 8.
Gold was the lifeblood of South Africa. The way its dug out has changed little since apartheid when underpaid black miners often worked in mortal danger. At its worst, more than 800 workers a.
Mar 10, 2020nbsp018332The warmest year so far was 2016, but that could be topped soon, said WMO Secretary-General Petteri Taalas. Given that greenhouse gas levels continue to increase, the warming will continue. A recent decadal forecast indicates that a new annual global temperature record is.
According to Heppel, at the onset of the COVID-19 pandemic, there was a negative sentiment about the Electric Vehicle EV industry, particularly in large markets such as Europe and China. As a result, that would have had an impact on battery metals such as cobalt of which the DRC is a key mining player.
It is a pattern seen in various parts of the world children being sickened from exposure to lead from mining activities. But the scale of the problem in Nigerias gold-mining region of Zamfara is unprecedented More than 400 children have died and thousands more have been severely poisoned by exposure to lead dust.
Solutions to global warming in Africa include effective land use planning to avoid forest degradation, developing renewable energy, and limiting the expansion of coal-fired power plants. Although the countries of Africa have some of the lowest overall and per capita global warming emissions on the planet, they are also likely to suffer from.
COVID-19 gave us a lot to be worried about when it came to EV demand but instead we can expect sales to be largely flat year on year. As such, concurrent demand for cobalt, lithium, graphite and copper will not be as bad as originally expected.
Tuma Waku added that demand for copper and cobalt demand will also be in demand as China resumes building its economy. The Chinese have a lot of interest in the DRC and put measures in place in order to continue operations during the State of Emergency in the country, he explained.
This gave the market some confidence to stem the fall of commodities as China remains committed to keeping production levels at 2020 levels despite the pandemic. This resulted in a positive upswing for copper and cobalt since March, almost getting back to levels where they were at the end of 2019.

Oct 13, 2013nbsp018332The infamous hole in the ozone layer above Antarctica may have caused warming in southern Africa over the past two decades, researchers say. to the South.
Under the 2015 Paris Agreement, 195 countries pledged to limit global warming to well below 2.0176C, and ideally not more than 1.5176C above preindustrial levels.That target, if pursued, would manifest in decarbonization across industries, creating major shifts in commodity demand for the mining industry and likely resulting in declining global mining revenue pools.
Global warming is the constant increase of temperature in the earths atmosphere that is caused by the increase of carbon dioxide, chlorofluorocarbons, greenhouse gases and many other pollutants. Chlorofluorocarbons are any type of compounds of carbon, hydrogen, chlorine, and fluorine which are harmful to the ozone layer.
Gold mining is becoming an increasingly dangerous threat to the Amazon. A new study has found that barely any trees or plants grow where mines once sat. This is bad news for the wildlife that depends on vegetation for habitat. Without trees or vegetation, though, the Amazon also cant store as much carbon to prevent further global warming.

Gold mining has much longer-lasting consequences on forests than other drivers of deforestation, authors Michelle Kalamandeen, a postdoctoral researcher at Cambridge University, and David Galbraith, an associate professor at the University of Leeds, wrote in an email statement to Earther.Our study indicates that active restoration will be required in order to recover forests from mining.
Mining activity has been growing in northern Amazonian countries such as Guyana and Venezuela. Small-scale mines are the main drivers of the devastation, which can also contaminate the broader environment if toxic contaminants travel spill into waterways waterways or leach into the soil. This is of particular concern for the Indigenous communities that live in and rely on the forests resources to survive.
The study authors installed nine monitoring plots in two central gold mining areas in Guyana from January to March 2016. They then checked back in on them between June and August 2017 to look for saplings, individual trees, or seedlings. They had to ultimately exclude nearly half of the plots because miners had already begun to re-mine them by 2017, which is another issue altogether and may have an even bigger impact on mercury concentrations.
Not only does this have serious consequences for our battle against global warming by limiting Amazonian forests ability to capture and store carbon, but there is also a larger implication of contaminating food sources especially for indigenous and local communities who rely on rivers, Kalamandeen said in a statement.
The authors would like to expand this research into Brazil or Peru and do long-term monitoring to better understand the true extent of ecological damage as well as what it could mean for the climate. Natural carbon sinks like the Amazon are an invaluable resource in global efforts to pull carbon out of our atmosphere and prevent further global warming. However, the forest needs its own protection from deforestation for agriculture, mining, and other extractive activities. Otherwise, there will be no trees left to absorb our excess carbon emissions, and well be left suffering.

Industry and transport are the two big offenders. Since coal is the main source of greenhouse gas emissions, cleaner ways of burning coal and cleaner fuels must be found. Eskom and Sasol account for nearly 90 per cent of all coal burned in South Africa at 65 per cent and 24 per cent respectively. Industry needs to be more energy efficient. The government needs to impose strict emissions audits so it can be determined who the polluters are and then keep them accountable.
As for transport, buses, mini-bus taxis, trucks and private cars are the bulk of South Africarsquos road users. Their exhausts spew out greenhouse gases, carcinogens and other noxious pollution daily as they clog up South Africa39s roads. Each year the same 20 km trip seems to take that bit longer and it39s only getting worse in the Western Cape as Somerset West and the northern suburbs bulge with ongoing urban sprawl. Of course, Johannesburg39s traffic problems make those of Cape Town look like a kid39s party.
A South African gold mine that goes two miles beneath the Earths surface holds far more than just precious metals.
In the early morning light, tall mine shafts loom over the Vaal River basin two hours southwest of Johannesburg. This once was a booming gold field, now most mines lie abandoned but Moab Khotsong is bustling. Long before the sun rises, thousands of miners start lining up for the triple-deck elevator called the cage. Its jammed but more always push on, and early one morning, so did we.
Were packed in as tight as sardines, the electric bells signal were ready, and the cage drops. Slowly at first, then picks up speed fast. We plunge 450 stories straight down. Its the longest elevator ride on Earth.
The cage rattles and whistles as we descend, the air gets more humid the deeper we go. Our lifeline to the surface is a machine called the manwinder, massive coils of steel rope two inches thick that attach to the cage and unspool faster and faster. We dropped two miles in a couple of minutes and emerged in an underground city.
To get to the gold, miners must walk miles through a vast maze of dimly lit tunnels. Sometimes youre lucky and can catch a ride, but mostly you just walk. For Leroy Lee, its in the blood. His father worked in the mines. Now its his turn. His family depends on his job.
The gold in these ultra-deep mines is found in narrow veins, laced through the rock. Some are no wider than a pencil. Its cramped at the rock face and we crouch alongside the miners as they work hunched over in the dark. The noise from the drills is deafening. Massive air conditioners cool the tunnels but it can still reach 120 degrees down here.
