the role of crushing ore grinding in mineral processing

Crushing grinding and milling are very important in mineral processing and materials engineering The size of the mineral particles must be reduced to the extent that the useful minerals and gangues are sufficiently dissociated or the useful minerals are exposed for chemical action

As a rule comminution begins by crushing the ore to below a certain size and finishes by grinding it into powder the ultimate fineness of which depends on the fineness of dissemination of the desired mineral
