The first mention of the systematic extraction of copper ore comes from about 3800 B.C. when an Egyptian reference describes mining operations on the Sinai Peninsula. In about 3000 B.C., large deposits of copper ore were found on the island of Cyprus in the Mediterranean Sea.

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.

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO 3.Cu(OH) 2. This experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent. Lesson organisation

Malachite -

Malachite is a copper bearing mineral, with as much as 58% copper content. The distinctive bright-green hydrous CARBONATE MINERAL malachite is a common but minor ore of copper. It is usually found in copper deposits associated with LIMESTONE, occurring with AZURITE as the weathering product of other copper ore minerals.

Dissolution of copper and iron from malachite ore and ...

The present work describes an investigation of a chemical process for the recovery of copper and iron from malachite ore. For the dissolution of copper and iron, H 2 SO 4 was employed as well as H 2 O 2 as an oxidizing agent. The effects of reaction temperature and time, acid concentration, liquid-to-solid ratio and agitation rate on the copper and iron percentage were investigated.
