The aim of a mineral processing operation is to concentrate a raw ore for the subsequent mineral extraction stage. Usually, the valuable minerals are first liberated from the ore matrix by comminution and size separation processes (crushing, grinding, and size classification) and then separated from the gangue using processes capable of selecting …

While we do represent two nationally leading underground detention systems, our options are not limited to just that. We also look at multifuctional design approaches such as permeable pavements and bioretention systems to gain additional storage volume at little to no added costs, lowering the total cost of the solution.

The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh). Then the ore passes to a three-stage, acid-circuit flotation process.
