It is no longer considered to be new or risky technology and many new concentrators have incorporated column cells into the flowsheet. The froth washing system on flotation columns serves two purposes. The first is to provide water for froth stabilization and the second is to displace the process water which normally discharges with the froth.

What is Feldspar. Feldspar is the name given to a group of minerals distinguished by the presence of alumina and silica (SiO 2) in their chemistry. This group includes aluminum silicates of soda, potassium, or lime. It is the single most abundant mineral group on Earth. They account for an estimated 60% of exposed rocks, as well as soils, clays ...

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...
