In mineral processing operations, liberation degree of the valuable mineral from the gangue determines the economic efficiency and effectiveness of downstream separation processes. This parameter mostly depends on the texture of the ore and to a lesser extent on the comminution process [ 17, 18, 19 ].

— For cross-stream sample cutters, which extract primary samples of slurry from a continuously flowing (process) slurry stream, these rules are: 1. The sample cutter must be non-restrictive and self-cleaning, discharge completely. 2. The geometry of the cutter opening must be such that the cutting time at each point in the stream must be equal.
In many mineral processing applications, the focus is to maintain maximum recovery of the valued mineral or element while also maximizing upgrade or concentrate assay. ...
