Copper Copper Principal compounds Copper forms compounds in the oxidation states 1 and 2 in its normal chemistry, although under special circumstances some compounds of trivalent copper can be prepared. It has been shown that trivalent copper survives no more than a few seconds in an aqueous solution. Copper(I) (cuprous) compounds are all diamagnetic and, with few exceptions, colourless.

Rocks that turn green and then red seems to me like you might have some copper sulfides, like chalcopyrite (CuFeS 2). At first, the copper reacts with the atmosphere to form something like malachite (similar to the green patina observed on things like the Statue of Liberty). Next, the iron oxidises to form iron oxy-hydroxides (as you correctly identified).

B. Processing of Sulfide Ore Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.

The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper. This is cast into slab-like anodes. Principal impurities are iron and precious metals (gold and silver). The anodes are electrolytically refined in cells sketched in Fig. 8.There is a resemblance to the cell of Fig. 7.
