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.

Copper electroplating fundamentals
The concept of copper electroplating is straightforward: Submerge the wafer to be plated into an electrolyte bath, apply a current, and copper ions will migrate and deposit onto regions with a pre-existing metal seed layer. The electrolyte bath contains three primary inorganic components: Copper sulfate (CuSO4) provides a source of copper ions.
