general principles of mineral ore grinding

Basic Mining and Processing Principles

characteristics of the ore body determines how the ore will be mined and the processing method that will be used to extract the metal. Because economics play a significant role in mineral and metal recovery mine operators avoid costly process steps such as grinding, and roasting where possible.

as to make separation between them. Such a phenomenon of making the mineral grains free from gangue in an ore is termed as liberation. This is practically carried out by size reduction performed by crushers and grinding mills. The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm.

Mineral processing - Wikipedia

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
