Froth Flotation and Gold Extraction

Jul 23, 2014Most methods of water-based gold extraction are dependent on gold's lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Get price

Apr 25, 2018These processing methods can include further grinding, concentration, pressure oxidation, and roasting, which is used to treat these ores to expose the gold particles prior to cyanidation. The crushed ore undergoes an agglomeration stage, after which the agglomerated ore is deposited onto the heap leach pad. Get price

How Is Gold Extracted From Gold Ore?

Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. Get price
