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.
