ore than the net tonnage of copper in the ore.5 A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore. However, because the rich ore contains more copper, it requires less of these inputs per tonne of copper recovered. The gross tonnage basis for costs is particularly important in
Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a coproduct, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.

Nov 04, 2013 · Toquepala produced about 152,000t of copper in 2012, including 120,000t of copper concentrates and 32,000t of copper hodes. Ore is extracted from the Toquepala porphyry copper deposit loed in the southernmost Andes Mountains of Peru. The extracted ore is refined at an onsite concentrator with a milling capacity of 60,000tpd.
Therefore, NSR for copper concentrate=٣.28 t −1 of ore. b. Zinc. Assuming that all the zinc is contained in the mineral sphalerite, maximum zinc grade is 67.1% (assuming sphalerite is ZnS). If Z is weight of zinc concentrate per 1,000 kg of feed, then for recovery of zinc into this concentrate:

Copper processing is a complied process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called hodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an openpit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains.The mine is the largest manmade excavation in the world and is considered to have produced more copper than any other mine in history – more than 19 million tons.
Most of the copper ores mined in the United States contain only about 1.21.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 %
FCX''s South America mining operations include openpit mining, sulfide ore concentrating, leaching and solution extraction/electrowinning. Production from these mines is sold as concentrate or hode under longterm contracts. Our South America mines also ship a portion of their copper concentrate to Atlantic Copper, our wholly owned smelting and refining unit in Spain.
Coppercontaining rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue.
A copper concentrator is milling 15,000 tons/day of a chalcopyrite ore assaying 1.15% copper. The concentrate and tailings produced average 32.7% and 0.18% copper, respectively. I let you do the math! Three product (bimetallic) formulas

Handling guide for copper concentrate in bulk Although copper occurs naturally in a pure state, it''s primarily mined from the minerals chalcopyrite, bornite, and malachite. Copper ore is extracted form the earth, then converted into copper concentrate, which is then roasted, smelted and converted into refined copper.

Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals
flotation, remove most of the waste rock and concentrate the minerals into approximately 25,750 tonnes of concentrate containing gold and copper. That is nearly a 200 times reduction in mass which then makes the resultant concentrate valuable enough to sell We can never recover of the gold, silver and copper from our ore.
A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation.
