The fragmentation of the minerals from each other during the grinding stage establishes the limits to process metallurgy. The relative abundance of the different minerals in the ore sample dictates the complexity of the flowsheet design. Here we discus the mineral composition and distribution of minerals by classes in the flotation feed stream.

Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are: To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation.

Grinding (and/or milling, which is a form of grinding) is accomplished by abrasion and impact of the ore by the free motion of unconnected media such as rods, balls, or pebbles. Crushing is ...
