Industries & Professions /
There are basically three categories in which metallurgical engineers work. Extractive metallurgists, also known as chemical metallurgists, are concerned with the methods used to separate metals from ores, and the reclamation of materials from solid wastes for recycling. As part of their responsibilities, they may supervise and control concentrating and refining processes in commercial mining operations. They may determine the methods used to concentrate the ore by separating minerals from dirt, rock, and other unwanted materials. Many of these separation methods are performed at a treatment plant or refinery. There the extractive metallurgist may supervise and control both the separation processes and final purification processes.
