Summary:
On December 26th, 2018, the Phase II copper and cobalt project of Kolwezi copper mine started its trial production. Later on, the company continued to optimize the flow sheet and construction organization. Within 4 months, it got through all the production processes and produced the first batch of cathode copper products, establishing a new image for the construction and operation of Zijin Mining's overseas projects, and for the company's implementation of the “One Belt and One Road” Initiative.
The Phase II project began on March 24th, adopting processing method as crushing, grinding, solvent-extraction, electrowinning, and cobalt precipitation. The designed production of Phase II is 50,000 tonnes of copper, 3,000 tonnes of cobalt.
Products:
- Sulphuric copper concentrate;
- Blister copper;
- Copper cathode.
