Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990).
"Gold tailings are materials remaining after extracting the desirable fraction from the uneconomic fraction (gangue) of the ore. Tailings vary, from overburden, which is the waste rock, to other material that encases an ore or mineral body, and which is displaced without processing during mining," explains Loots.
