COPPER SUPER CONCENTRATE PRODUCTION TECHNOLOGY

flotation with Cu–Mo concentrate production. Then, the con-centrate either goes to final concentration for production of bulk concentrate with the copper content in accord with the quality standard 1, or is sent to selective flotation with self-con-tained process stages of copper2 and molybdenum scaveng-ing.

COPPER Copper production - TU Delft

Copper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

Copper Ore Processing Methods

Apr 11, 2017  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.
