Secondary collectors, or promoters, can further increase recovery, with dithiophosphates being the most widely used promoters in gold flotation (OConnor and Dunne, 1994).
Factors affecting Gold Recovery from Secondary Ore IAENG tailings from earlier gold processing steps. The cyanide concentration, residence time and lixiviant pH have a significant effect on the leaching efficiency of gold.
The carbon in pulp (CIP) and carbon in leach (CIL) processes became firmly established in the gold mining industry in the 1980s, initially in South Africa and Australia, from where they spread rapidly to all the gold producing regions of the world.
Underlying physical and chemical processes of formation are common to many metallic and nonmetallic ore deposits. A good deal of data is lacking about the processes of ore formation, ranging from how metals are released from source rocks through transport to deposition and post deposition alteration.
The effect of these parameters on gold recovery in Aghdarreh ore is investigated using the Tagouchi The dissolved Oxygen is one of the most important factors affecting the gold cyanidation process. Agitation speed is one of the important factors in gold leaching process and the dissolution rate of gold
Other factors affecting gold leaching kinetics are grain size, agitation speed, temperature, pressure, foreign ions, cyanicides and carbon preg robbing  . In the cyanidation process, it is
