What Is The Crushing Process
Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushing ...
what is the platinum mining process
The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
