Mineral Comminution and Separation Systems
Most mineral processing operations are conducted with water as the medium. This is called wet process against dry process, which is performed without wate r. The reason for this is mainly for the advantage or the necessity of the separation process. Normally processing of a ton of ores, several tons of water is needed, even if part of the water

Introduction to Mineral Processing or Beneficiation
The products from AG or SAG mills typically feed secondary grinding mills with particles that range in size from 5 cm down to below 100 microns (0.1 mm). The final particle size is determined by downstream processing requirements. Grinding is carried out as a wet process with water content between 50 – 70% by weight.

Hint: to highlight K-feldspar, switch to a medium or low magnification objective (usually 4 or 10X works well), mostly close the substage iris, and raise the stage slightly (yes, raise). Though the image will be somewhat out of focus, the low index K-feldspar grains will be surrounded by bright Becke lines just inside the grain boundaries.
