Beneficiation

The goal of beneficiation is to increase the concentration of valuable metals in the ore while reducing the quantity of waste material. Effective beneficiation can lead to lower production costs by maximizing the yield of usable material from raw ores.

Mining and Refining – Process

Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting. Beneficiating ore also reduces the amount of material that needs to be transported and processed at the refinery.
