The Molulu Project is an ex-producing medium-scale copper/cobalt asset in the Katangan Copperbelt, adjacent to producing mines. Previously mined by artisanal miners from 4 pits. The Molulu asset commenced production in Janiary 2023, generating near-term free cashflow. The Molulu Project's copper grades range between 15% & 40% (sulphides) …

AnInvestigation into heLeaching Kinetics of a Cobaltite Ore with Ferric Sulfate Solutions. A method for the xtraction of cobalt from cobalt-arsenic-sulfide (cobaltite) ores or con-centrates has been identified. The method utilizes anatmospheric oxygen-acidic ferric sulfate leach, at temperatures up to 373 K (100~ to place thecobalt insolution.

In 1969 the Zambian government nationalized the copper-mining industry, which was then to be run by a parastatal organization, Zambian Consolidated Copper Mines. By the mid-1970s the price of copper on the world market had steeply dropped, resulting in a damaging economic decline. In the 1990s the mining industry began to be privatized, …

We studied the structure of the copper–cobalt (CuCo) surface alloy, formed by Co deposition on Cu(110), in dynamic equilibrium with CO. Using scanning tunneling microscopy (STM), we found that, in vacuum at room temperature and at low Co coverage, clusters of a few Co atoms substituting Cu atoms form at the surface. At CO pressures …

The west limb of the Nkana Syncline hosts a currently uneconomic copper resource estimated at 91Mt @ 2% with an average true thickness of 2.3 m. Oxidation of the primary sulphide orebody has taken place to a depth of at least ~100m, along the …

The framework comprises seven goals: Compliance with the OECD Due Diligence Guidance for Responsible Mineral Supply Chains from Conflict-Affected and High Risk Areas. Our cobalt and copper is sourced without child labour. Clean cobalt and copper is traceable. Clean cobalt and copper is not sourced from artisanal and small-scale mining.

The Elizabeth Creek Copper Cobalt Project is centred approximately 30 km south-east of Woomera and 135 km north-west of Port Augusta in South Australia. The project currently covers 701 km 2 in the Olympic Dam Copper Province, Australia's most productive copper belt. The project is located 100 km south of BHP Billiton's Olympic Dam copper ...

Most copper-cobalt smelter slag is processed in Zambia for metal recovery at great cost by remelting the quenched smelter slag and reprocessing. In Zambia, the Cu /Co ~10, since cobalt is nearly 5 times dearer than copper, losing ... Nchanga, Nkana and Baluba froth flotation concentrates from Zambia were used in this investigation and ...

The structure of alumina-supported copper–cobalt catalysts prepared by incipient co-impregnation was studied by using a combination of various characterization techniques including in situ XRD, XPS, TPR, XANES/EXAFS, in situ magnetic method, and TEM. The results suggest a much higher dispersion of copper than cobalt on γ-Al 2 O 3 …

An ammonia-based system was used to selectively leach cobalt (Co) from an African high-silicon low-grade Co ore, and the other elemental impurities were inhibited from leaching in this process. This process was simple and environmentally friendly. The results revealed that the leaching ratio of Co can reach up to 95.61% using (NH 4 ) …

On average, you can expect to pay around $25/kg for cobalt compared to just $2/kg for copper. Properties. The properties of cobalt and copper vary greatly depending on their composition and form factor. As a pure element, cobalt has a higher melting point than copper (2723°C vs 1083°C). Additionally, cobalt has higher strength …
