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

Sep 26, 2019· Sulfide Copper Ores . Virtually all sulfidetype copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

1. Introduction. Gold and silver are commodities which occur in many types of hydrothermal ore deposits and geological contexts (Zhu et al., 2011).The mineralogy of gold and silver is variable within and across these different deposit types, with both noble metals known to occur as native metals and alloys, and in stoichiometric amounts in, e.g., sulfides, sulfosalts, selenides, tellurides and

Jun 13, 2016· Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods. Thirtyseven different heap leach operations with a total production of 198 tonnes of gold per year (6,150,
