The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore
Source Copper is occasionally found native (i.e. as the uncombined metal), and is also found in many minerals such as the oxide; cuprite (Cu 2 O), the carbonates; malachite (Cu 2 CO 3 (OH) 2)and azurite (Cu 2 (CO 3) 2 (OH) 2) and the sulfides; chalcopyrite (CuFeS 2) and bornite (Cu 5 FeS 4). Most copper ore is mined or extracted as copper sulfides.
