Copper processing
Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of …

Understanding XL Hopper Tank Designs for Dry Bulk Storage
The use of shop-welded steel hopper tanks is common in dry bulk storage applications. Typically, the average size shop-welded tank used to store bulk materials will range from 3500 to 7000 cubic feet per unit. In select applications, shop-welded hopper tanks can exceed capacities of 10,000 cu ft of storage.
Copper Mining and Processing: Everything you Need to Know
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
