Copper processing - Copper processing - Roasting, smelting, and 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 either the hearth or ...
Understanding Grades of Copper Scrap Monday, 10 April 2017. Copper is among the most valuable metals available when it comes to scrap collection and recycling. With an infinite recyclable life, copper is used and reused in motors, computers, construction, industrial machinery and more.
Concentrating. The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.
Post-consumer scrap or old copper scrap can be divided into a number of different grades, which also may vary between different countries.
