Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

After separation, the various concentrates are dried to the consistency of a damp powder before being stored in our enclosed storage and shipping facility.

Implementation and practice of an integrated process to

Aug 01, 2020 An integrated process to recover copper from low-grade copper grade sulfide ore and acid wastewater (AMD) has been developed and applied. The process includes the operations of milling-flotation, heap bioleaching, SX-EW and copper sulfide precipitation. In the process, copper and valuable metals are efficiently recovered.
