"It depends upon the ore and its density but, for copper, which we're really focusing on, you get an acceptable recovery in conventional flotation up to about 120 or 130 microns. Certainly, it drops off before 200 microns. "With CPF, you can usually take that up to 400 microns, which reduces the amount of grinding needed by half.

One large copper operation with two stage grinding and cyclone classification, actually treats cyclone underflow, — 20 plus 100 mesh, through Unit Cells. ... Hydrocyclones are used in many grinding circuits to make a size separation which ideally sends the fine ore fraction to conventional flotation and the coarse fraction back to the …

range of optimal particle size. The mechanism for flotation losses with coarse ore particles has been reported (Falatsu, 1989) and is well accepted, but has not been addressed by conventional flotation equipment manufacturers. For example, audits of two world class copper producers have shown 35-60% of copper and

The aim of the paper was the analysis of the influence of milling time on the laboratory flotation of the copper ore from stratiform Polish deposit. Three different milling time of copper ore in laboratory ball mill was …

The aim of the paper was the analysis of the influence of milling time on the laboratory flotation of the copper ore from stratiform Polish deposit. Three different milling time of copper ore in laboratory ball mill was applied. The flotation results were presented as the recovery-recovery and grade-recovery upgrading curves.

Asghari et al. [27] investigated the improvement of copper recovery in an industrial flotation circuit (Sarcheshmeh copper mine), and stated that about 95% of overall copper lost in final tailing was in the rougher circuit while the rougher flotation recovery of mixed copper ore was 8% less than the sulfide ore.

This report provides a perspective on the amount of water used by a conventional copper flotation plant. Water is required for many activities at a mine-mill site, including ore …
