The New Concentrator of Kipushi (NCK) is a typical example of a plant processing high talc-containing copper-cobalt ore, the simplified flowsheet is given in Figure 1. At NCK, the beneficiation of copper and cobalt ore involves a combination of concentration by froth flotation and classical gravity separation by spirals and shaking tables.

The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams. Material in process often cannot be weighed without a ...

The reduction of talc recovery in copper-cobalt flotation concentrates is very crucial. In fact, a high talc content into the concentrate lowers the copper-cobalt grades and causes problems in the smelters due to the resulting high MgO content, forcing the smelter operators to impose penalties for the concentrators.

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
