Operations are drilling (blasting), primary crushing (optional) and materials handling, dry and wet. 5. 5 Drilling (and blasting) is the technology of achieving primary fragmentation of "in situ" minerals. This is the starting point for most mineral processes with the exception of natural minerals in the form of sand and gravel.

The product from crushing circuits often go to grinding mills which the material is ground from a F80 of up to 1″ (25mm) to fine dust of under 30um. Grinding mills used in Mineral Processing are rod and/or ball mills, SAG/AG/FAG Semi-Autogenous or Fully-Autogenous mills as well as the now less popular pebble and roller mills.

Minerals are crushed to various sizes, depending on their mineral composition, concentration and nature of the use. During the mineral dressing crushing is used for separation of aggregates of metallic and nonmetallic minerals, which are contained in the source material. After all the steps of crushing the ore is fed to the wet or dry shredding.
