Comminution is particle size reduction by breaking, crushing, or grinding of ore, rock, coal, or other materials. Comminution is a critical component of most mineral processing flowsheets and serves several purposes, including: Liberating valuable minerals that are locked within waste rock. Increasing available surface area for chemical reactions.
Power in Comminution Circuits • Comminution circuits consume between 10-20 kWh/t of ore • This can be broken down into: – crushing consumes 0.7 - 3.6 kWh/t – grinding consumes 6 …
Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".
Aug 01, 2017· Comminution is the breaking of larger rocks into smaller ones through crushing, grinding, or other processes. In copper mining, it is used to crush the ore to a fine powder. In this powder form, froth flotation tanks can be used to separate the copper concentrate from the gangue (the remainder of the mined material).
