By Oscar Nkala British miner Alexander Mining Plc says its subsidiary MetaLeach Limited has been granted the African Regional Intellectual Property Ownership (ARIPO) patent in Zambia for a method for leaching cobalt from oxidised and non-sulphide cobalt ores. In a statement, Alexander Chief Executive Officer Martin Rosser said IPO patent number

5-10-2018With the global transition to electric vehicles (EVs), corporations are increasingly forced to rely on cobalt from the Democratic Republic of the Congo (DRC), where a culture of corruption, unscrupulous mining practices, and political instability threaten supply security.

China's Zhejiang Huayou Cobalt will terminate its investment in a cobalt mine operated by New Minerals Investment (NMI) in the Democratic Republic of Congo (DRC) because of a weak cobalt market. Our website uses cookies to ensure that we give you the best experience on our website.

Jefferson and Erwin Reisner* We report on a cobalt sulphide (CoS) electrode prepared by simple and scalable chemical bath deposition (CBD), which performs as a highly efficient and robust electrocatalyst

10-4-2019Arc Minerals reported that the Kalaba Demonstration Pilot Plant has now been completed and successfully commissioned with the initial production of copper/cobalt sulphide concentrate. The Company is finalising detailed oxide resource tonnages, grades and

Cobalt is the most expensive raw material inside a lithium-ion battery. That has long presented a challenge for the big battery suppliers — and their customers, the computer and carmakers. Engineers have tried for years to craft cobalt-free batteries.

Boss Mining produces cobalt oxide and sulphide concentrate, cobalt carbonate and copper cathode and is located in the south-eastern Lualaba and Katanga provinces. It operates in Lubumbashi, Kakanda and Luita and includes open cast mines, crushing- beneficiation- and concentrator plants, as well as an electroextraction facility.

18-8-2017There are other miners on the ASX with cobalt operations in the DRC – Nzuri Copper (NZC) and Tiger Resources (TGS). Finally, venerable ASX blue chip BHP Billiton (BHP) could be tempted to add cobalt extraction to their substantial stable of copper and nickel mines.

The KOV mine is the largest high-grade copper resource in the world. It comprises four ore bodies, Kamoto East, Oliveira, Virgule and FNSR, accessed via two pits, Kamoto East and KOV. The Kamoto East pit was operational from 1960 to 1985 and the adjacent

Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military applications, many of which are strategic and critical. On a global basis, the leading use of cobalt is in rechargeable battery electrodes. Superalloys, which are used to make parts for gas turbine engines, are another major use for cobalt. Cobalt is also

23-2-2018Kevin Torudag, President of Bankers' DRC subsidiary states, "Bankers controls a superior DRC exploration land portfolio, has an experienced board, and a first-class operating team fully functioning in the DRC. We are firmly established in the DRC where the needs of end-users will drive the demand for certified cobalt and copper resources.

The Kamoto underground mine is Katanga's primary sulfide ore source. It entered operation in 1969 under the DRC's state-owned mining company Gcamines. During the 1980s it produced an average of three million tonnes of ore per year and, prior to its restart under Katanga's ownership, the mine had produced a total 59.3

Just a couple months ago in April, I went to the DRC together with team member Sylvain, to continue our quest for more responsibly mined materials. This time was all about cobalt, a critical material we need to produce our battery. For some part, we were joined by a documentary crew that is following us []

19-1-2016Potential DRC cobalt supply chain. Amnesty International contacted 16 multinationals who were listed as customers of the battery manufacturers listed as sourcing processed ore from Huayou Cobalt. One company admitted the connection, while four were unable to say for certain whether they were buying cobalt from the DRC or Huayou Cobalt.

8-8-2019The DRC produces most of the world's cobalt supplies, but the country's 81m citizens derive few benefits from it. Economic growth has slowed, falling from 9.4% in 2014, to 3.9% in 2018. With a GDP of $42.6bn, the IMF ranks the DRC at 92 out of 192 countries.

Given that more than half the world's cobalt comes from the DRC, that one fifth of it is extracted by artisanal (or informal) miners, and that around 40,000 children work in southern DRC where the cobalt is mined, there's a chance that our phones contain child labour.

We produce cobalt mainly as a by-product of copper mining in the Democratic Republic of Congo (DRC), but also as a by-product of nickel mining in Australia and Canada. We are also one of the largest recyclers and processors of cobalt-bearing materials, such as used batteries – helping secure the supply of the metal at a time of increasing demand.

World terrestrial resources of cobalt are 25 million tonne, with the vast majority of the resource in sediment-hosted stratiform copper deposits in Congo and Zambia. In Australia resources of 1 Mtonne of cobalt metal occur mainly in lateritic nickel deposits, also magnetic Ni-Cu sulphide deposits in mafic and ultramafic rock. Musgrave Province
