How much metal does the ore contain? « World Ocean ReviewOne example is copper. Copper ore does not contain pure copper, but either a copper-sulphur-iron compound (chalcopyrite) or a copper-sulphur compound (chalcocite). The metal must first be separated from such minerals by means of multi-step metallurgic processes. In many cases these processes are so complicated.CHM 130 Analysis of Copper Ore for Cu ContentMining the ore out of the ground is not complicated, but extracting the copper metal from the ore can be. . analyze the amount of copper extracted from two different types of copper ore, azurite and malachite.
