Mineral processing

Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

Montana Cyanide Process Open Pit Mining Prohibition, I-137

Cyanide leach mineral processing is the procedure used in mining operations that applies a cyanide-based solution over gold or silver ore to remove the precious metals from the waste rock, so the metals can be recovered. This measure would prohibit new open-pit gold and silver mines in Montana that use heap and vat cyanide leach processing.

The separation of minerals from gangue is called mineral processing. Oftentimes, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals. As values of minerals increase, it can even be profitable to reprocess gangue to extract additional minerals that may have been missed during the first processing.
