Native copper, for example, is an ideal copper ore mineral. Ideal ore minerals are, however, uncommon. The most commonly mined ores are not ideal. ... We can use a triangular diagram to plot the compositions of …

2.6: Classes of Minerals

Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–.

Producing Copper Nature's Way: Bioleaching

Further, through the use of biooxidation, it is now possible to leach many of the copper sulfide minerals present in the ore. While chalcopyrite remains refractory to ambient temperature bioleaching, other copper sulfide …

The Extraction of Copper

In the copper(I) sulfide, the copper is +1 and the sulfur -2. The oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. In sulfur dioxide, the oxygen has an oxidation state of -2 and the sulfur +4. That means that both the copper and the oxygen have been reduced (decrease in oxidation state).
