— Gold flotation is widely used in the case of refractory ores, in which small-sized gold particles, locked within sulfide minerals, are recovered through flotation of gold-bearing minerals (Marsden and House, 2006). It is also an effective means for separating free gold from silicate particles present in ore.
— The ore quality, and density of a rock or metal ore, as well as its occurrence type, can directly affect the ore mining costs. It is therefore necessary to weigh the extraction cost against the metal value contained in the rock to determine which ore can be processed and which ore is too low a grade to be worth mining.
