Copper processing Ores Britannica

To increase the recovery of copper and reduce losses, the tailings are frequently reground and passed through a second flotation, the concentrate from which is combined with the initial production. The flotation concentrate is then dewatered and filtered to produce a filter cake that is sent to a copper

Effect of Copper and Iron Ions on the Sulphidizing

Abstract. The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na 2 S, CuSO 4, and FeCl 3 on sulphidizing flotation of copper oxide. The results show that a proper Cu 2+ concentration can increase the sulphidizing effect of copper oxide, while Fe 3+ inhibits the sulphidizing effect. Further analysis shows that Cu 2+ ions can reduce the

3 Copper

The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
