May 18, 2021 Many mines produce mixed ores where nickel, zinc, or lead are also refined and sold as by-products. Copper is the 25th most abundant element in the earths crust at about 0.06-0.1 on average. Copper deposits are typically only developed if there is more than 5 kg of copper per tonne of rock 0.5 by mass.

CuAu atomic ratios of porphyry copper ore deposits form a continuous range from about 5000 to 5,000,000 with a median near 40,000, which separates gold-rich and gold-poor deposits. Gold is found in porphyry copper deposits in solid solution in CuFe and Cu sulfides and as small grains of native gold, usually along boundaries of bornite.

The Nchanga Cu-Co ore deposit of the Zambian Copperbelt, is hosted in Neoproterozoic siliciclastic-carbonate sedimentary rocks, and it consists of two orebodies the Lower Orebody shale and the Upper Orebody arkose. Refractory Cu ores present in the Upper Orebody comprise 150 Mt with average 0.87 Cu, and are characterized by inadequate recovery of copper by leaching.
factor of around 80 based on average crustal abundance. Copper occurs naturally in all plants and animals, as it is an essential element for all known living organisms. It is one of the transition metals in the periodic table which means it can form compounds, such as chalcopyrite the main copper ore CuFeS 2, and copper ions Cu or

Prospecting from Orbit. Mining for ore isnt what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.
