2020-9-28  Primary copper production begins with the extraction of copper-bearing ore by means of open-pit mining, underground mining or leaching (see diagram 1). Copper ore is not usually exported, since most of it is gangue, which has no commercial value (OECD, 2015). Ore is processed in one of two ways, depending on whether it is oxide or sulphide ore.

Primary Metal Production - Chemical Engineering

2009-12-4  Molten metals tend to dissolve impurities from the ore. For example, many ores that contain native copper have arsenic compounds associated with them. When the ore is melted, the molten copper dissolves the arsenic. As a result, the metal from the furnace can be less pure than the individual metal grains that were originally in the ground.
