froth flotation for gold

Tailingsinfo What are tailings?

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).
