composition of zinc ore before it goes into crusher

3 Technologies in Exploration, Mining, and Processing

After a mineral deposit has been identified through exploration, the industry must make a considerable investment in mine development before production begins. Comminution (i.e., the breaking of rock to facilitate the separation of ore minerals from waste) combines blasting (a unit process of mining) with crushing and
