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).

Mineral Land Regulation & Reclamation

Spatial gradients for Pb and Zn were calculated using an ordinary kriging interpolation algorithm. A spatial pattern was identified by a GIS method to visualize maps over the Pb-Zn ore mining area. The accumulation of Zn (R2 = 0.74, p < 0.05) and Pb (R2 = 0.85, p < 0.01) in plant tissues correlated with soil concentrations.

When the desired metal is removed from ore, waste materials are piled up in what are called the tailings. The amount of tailings a mining operation produces far outweighs the amount of usable ore they get from the same site. For every 20 pounds of chalcopyrite, you might get only about five pounds of copper.
