Takes place in a series of agitated leach reactors or pachucas Before leaching the pH of the pulp is normally adjusted to a value of around 9 5–11 to ensure minimum loss of cyanide as hydrogen cyanide The leaching of gold can be conveniently represented by the Elsener equation  Although air agitated leach tanks were commonly used in.
Recently leaching of gold with cyanide has come under scrutiny for its possible detrimental effects to the environment Also in some gold bearing ores and concentrates conventional cyanide.
Flotation Circuits Flotation circuits are typically comprised of rougher scavenger and cleaner flotation banks Rougher and scavenger banks are focused on recovery and thus provide maximum residence time Rougher banks can be large with the number of cells being 5 or greater Scavenger cells are the last line of defense for avoiding losses.
