     · C.B. Fox Date February 15 2021 Copper sulfate which is used in electrorefining copper.. Copper cathode is a form of copper that has a purity of 99.95 . In order to remove impurities from copper ore it undergoes two processes smelting and electrorefining. The resulting nearly pure copper is an excellent conductor and is often used in electrical wiring.

    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.
