Definition of mineral processing
The dry and wet crushing and grinding of ore or other mineral-bearing products for the purpose of raising concentrate grade; removal of waste and unwanted or deleterious substances from an otherwise useful product; separation into distinct species of mixed minerals; chemical attack and dissolution of selected values.

Essential Guide to Mineral Processing & Equipment
Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. Mineral processing is conducted at the site of the mine and is a highly mechanical process, with oversight from a central control room.

Comminution
Comminution in mineral processing. Comminution in the mineral processing industry is a physical pre-treatment method that involves ore milling, grinding and breaking. These mechanical methods increase the accessible surface area of the ore and its precious metals / materials through particle size reduction and size distribution.

By referring to the tables "Minerals and Their Characteristics" (pages 332-339) it is seen that the perfect grade of a copper concentrate will be 63.3% when the copper is in the form of bornite, 79.8% when in the mineral chalcocite, and 34.6% when in the mineral chalcopyrite. A common association is that of chalcopyrite and galena.
