Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
unintentional pyrite flotation is undesirable in a Cu-Au ore flotation circuit due to the detrimental effect on Cu final grade. Therefore, in order to improve final concentrate grade, pyrite depression strategies (e.g. aeration, sulphite, cyanide addition, etc.) have been used over the years to minimise pyrite recovery.
The refractory component of the ore is gold that is extremely fine and locked in arsenopyrite and pyrite minerals (sulphides). Conventional milling methods are not capable of recovering this type of gold. The Red Lake Complex processing plant employs a typical sulphide flotation circuit generating a bulk sulphide concentrate.

The flotation of gold-bearing ores is classified according to ore type (i.e. gold ore, gold copper ore, gold antimony ores, etc.), because the flotation methods used for the recovery of gold from different ores is vastly different. 17.2 GEOLOGY AND GENERAL MINERALOGY OF GOLD-BEARING ORES
The flotation of gold and silver minerals is mostly carried out in alkaline pulp medium, but for some gold-bearing pyrite and pyrrhotite, it is suitable for flotation in weak acid pulp medium. Oxygen has an effect on the flotation process of gold-silver sulfide ore oxidized to different degrees.
