Parametric Optimization in Rougher Flotation Performance

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH from 8 to 10 at low agitation rate 1000 rpm enhanced the recovery from 80.36 to 85.22 , while at high agitation rate 1200 rpm, a slight declination occurred in the recovery.

copper mining and processing from mine to copper plate

The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore ~ 0.5 mm going to froth flotation cells for recovery of copper.

Copper Ore an overview ScienceDirect Topics

Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an orewater pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineralwaterair froth.

Froth flotation

Principle of operation. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding a process knownminution so that the various minerals exist as physically separate grains.This process is known as liberation.The particle sizes are typically less than 0.1 mm 100 µm, but sometimes sizes smaller than 710 µm are required.
