Crushing Circuit Mineral Processing
Crushing circuits typically consist of several distinct stages, including primary crushing, secondary crushing, and occasionally, tertiary crushing. The primary crushing stage involves breaking down the ore to a manageable size using a primary crusher, such as a jaw crusher or gyratory crusher. ... Importance in Mineral Processing:

Run-of-mine ore is usually too large to be useful for construction or metallurgy. Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations, or facilitate mineral liberation; therefore, in the aggregates and mineral processing industries, run-of-mine ore is broken in crushing circuits by cone crushers.
