Mineral Processing - an overview | ScienceDirect Topics

Grinding is widely applied in mineral processing. There are two ways of grinding. (1) Agate mortar: the mineral sample and a little deionized water are placed in a pure agate mortar for artificial grinding. (2) Ceramic ball mill: the mineral sample and a little deionized water are put in the ceramic mill and ground with the ball.
