(Bio)Hydrometallurgy is a common technology in processing copper sulfide minerals. With the decline in ore grades and depletion of easily mined deposits, some complex ores with relatively small reserves need to be taken seriously. Bornite is one of the most important copper resources (following chalcopyrite and chalcocite) and the commonly associates in copper mines.

About 80% of the world's copper-from-ore is produced by concentration/smelting/ refining of sulfide ores. The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide, and chalcocite ores. Copper production from recycled end-of-use objects is about 15% of copper-from-ore copper production.

So I really like Bob's mods, and Angel's ore mods as well, but the production chains in Angel's seems a little forced, and the made-up ore types seem a little silly, when there are plenty of real ores to use. With that in mind, I was kicking around some ideas for a mod that would inject some needless realism into factorio ore processing.
