Copper concentrates produced by mines are sold to smelters and refiners who treat the ore and refine the copper and charge for this service via treatment charges (TCs) and refining charges (RCs). The TCs are charged in US$ per tonne of concentrate treated and RCs are charged in cents per pound treated, denominated in US dollars, with benchmark prices set annually by major Japanese smelters. The customer in this case can be a smelter, who on-sells blister copper ingots to a refiner, or a smelter-refin
Aug 09, 2020· In its outlook plan for the mining sector in the current Iranian calendar year (ends on March 20, 2021), Iran plans to produce 1.427 million tons of copper concentrate. The country had planned to produce 1.198 million tons of copper concentrate in the past year, while the output reached 1.18 million tons.
The copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities.
Sep 26, 2019· Sulfide Ores . Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
The copper concentrate and flux melt, and collect in the bottom of the furnace. Much of the iron in the concentrate chemically combines with the flux to form a slag, which is skimmed off the surface of the molten material. Currently over half the copper being produced in the United States comes from recycled copper. Fifty-five percent of

Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters.
Copper production begins with ore milling and copper separation by flotation in order to produce a concentrate with a copper content of about 30%. The produced concentrates are smelted to remove volatile and other impurities and by further purification of the copper melt from the smelter, a primary form of the metal, known as blister copper is
The early development of copper probably was most advanced in Egypt.As early as 5000 bce, copper weapons and implements were left in graves for the use of the dead.Definite records have been found of the working of copper mines on the Sinai Peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art of extracting the metal included some refining.
Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste; tailings, dump and heap leach wastes, and waste rock and overburden. The amount of marketable copper produced is small compared to the original material mined.
Nov 23, 2016· The table above shows a worst case scenario, a typical low grade copper mine using coal fired electricity would produce in the order of 3 5 t CO2e/t Cu produced. A large open pit copper mine may use in the order of 200,000 L/d of diesel, with an emissions factor of about 2.7 kg CO2 e/L, resulting in 200,000 t CO2 e/y of emissions.
From copper and nickel processing. Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace, and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy. In
