[edit] Mineral Processing/Ore Dressing

After mining the first step in the metallurgical process is mineral processing. This step prepares the ore for extraction of the valuable mineral. It is a process of physically separating the grains of valuable minerals from the waste minerals. This enrichment process considerably reduces the volume of mineral that must be handled by the extractive metallurgist. (See Mineral Processing Technology by B. A. Wills, First Edition 1979, Pergamon Press, Maxwell House, New York, 10523)
