Copper ores are of two kinds oxidized malachite and sulfide ores peacock ore or fahlerz. the distribution of both kinds on the surface of the planet is very uneven. there are no sulfide ores in the near east, one of the oldest centers for bronze metallurgy. on the other hand, the earliest evidence of copper mining refers to

The copper milling process involves trucking ore to ore bin above the crusher. upon crushing, it was sent by belt conveyor to a ball mill for fine grinding. iron pyrite was roasted in the adjacent sulfuric acid plant, and sulfurous gas mixed with the fine ore. the ore was washed and filtered, and the copper sulfate solution ran through tin
Besides, as compounds of copper are different in different ores, so the process of smelting is also different. let us consider the malachite, the most commonly found ore in the earth consisting of copper carbonate. to separate the copper from it, at first the part of carbon has to be driven out. copper-oxide will be obtained as a residual deposit.
Malachite is a copper carbonate mineral that occurs in distinct shades of green. apart from the obvious lapidary uses, malachite was valued as an ore of copper and as a pigment. the first uses of malachite can be traced back several thousand years back, to ancient egypt.
