The document discusses mineral beneficiation and comminution. It defines mineral beneficiation as the separation of valuable minerals from gangue in ore. Comminution, or size reduction, is the primary operation in mineral dressing and involves crushing and grinding the raw ore to liberate valuable minerals.
Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

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.
