Lead-Zinc ores - Danafloat

Flotation separation and recovery of lead and zinc concentrates from ores containing galena (PbS) and sphalerite (ZnS) is well established and generally achieved quite effectively. Silver often provides highly significant economic value, if not the greatest value, with the silver most often associated with the galena mineralization which is fortuitous since smelters pay more for silver in lead

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. It has been described as "the

Leaching of zinc from a lead-zinc flotation tailing

1/10/2017· Lead-zinc ores are concentrated adopting grinding followed by sequential flotation technique in which lead minerals are floated in the first stage further followed by flotation of zinc minerals. In this process some portions of lead and zinc are also lost as sulphide, oxide and mixed minerals into the tailings as metal losses.
