Froth Flotation Analysis of Oxidized Lead-Zinc Ore

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic,which is suitable for lead-zinc ore. But the flotation of oxidized lead-zinc ore is a difficult one. In the treatment of lead-zinc oxide ore, it is complicated to choose flotation reagent and process flow.

Why Only Sulphide Ore Is Concentrated By Froth

FROTH FLOTATION involves three different phases- solid (fine ore powder), liquid (water) and froth.This Froth is then removed and the concentrated mineral is refined.Other applications include the selective depression of polymetallic sulphide ores in the processing of iron ore.

2003-10-1  The flotation behavior of the oxidized, high-chromium PGE ores is different from that of the high chromium unoxidized ore. Specifically, the flotation activity of the gangue and chromium is more pronounced, and the oxidized PGE-bearing minerals are not readily floatable. Flotation studies on this ore were concentrated on examining the effectiveness of clay and gangue depressants, and on collectors
