than this is usually uneconomic unless the ore has a very high gold content. Often the gold bearing ores are refractory due to smallness of the gold grains and concentration by flotation is required, followed by roasting, bacterial leaching or pressure leaching to liberate the gold prior to cyanidation [5, 6, 7]. Studies were carried out on a sample previously investigated by the Mining ...

Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral–water–air froth. Noncopper minerals do not attach to the rising bubbles; they are discarded as "tailings." The selectivity of the process is controlled by chemical reagents added to ...

Flotation is a method of enrichment used to distribute particles, which differ in their surface properties. Hydrophobic solids intrinsically create contact at the solidliquidgas interface. However, not all minerals, including copper minerals, can be characterized by this crucial ability. In that case it is necessary to use the collector reagents which guarantees a high efficiency of the ...
