Accurate reporting is particularly important in the mining of base metals, says Smit, because the ores contain other metals. "When you mine gold, for example, you just get gold at the end. But when you mine a base metal such as copper, you can also produce by-products such as cobalt, gold and silver, depending on the specific ore."
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.

Nationalization and Mining: Lessons from Zambia budget deficit increased to US$150 million. Foreign debt of $2.6 billion had to be restructured. By 1986 a noticeable decline in copper production resulted in the closure of many mining units and led to the implementation of a five-year plan to revive the company8. This was not successful, and by
