Typical deposits range in thickness from 3 to 15 m. The majority of the bauxite can be mined and processed without beneficiation (further treatment of the ore to concentrate the minerals), but the ore in the north of Brazil and in Vietnam has a high clay content and has to be washed before processing.

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

Residual gold can be entrained in these streams. One of the most critical steps in the design of the plant is the control of the metal balance across the process, efficiencies of >99.98% are necessary. It is necessary to minimise the work-in-progress gold inventory and the time it takes to refine the incoming gold.
