copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. the smelters were initially located near the mines to minimize the cost of transport. this avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the coppercontaining minerals. however, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first.
initial concentration techniques included handsorting and gravity concentration. they resulted in high losses of copper. consequently, the development of the froth flotation process was a major step forward in mineral processing. it made possible the development of the giant bingham canyon mine in utah.
in the twentieth century, most ores were concentrated before smelting. smelting was initially undertaken using sinter plants and blast furnaces, or with roasters and reverberatory furnaces. roasting and reverberatory furnace smelting dominated primary copper production until the 60s.
the roasting process is generally undertaken in combination with reverberatory furnaces. in the roaster, the copper concentrate is partially oxidised to produce "calcine" and sulfur dioxide gas. the stoichiometry of the reaction which occurs is
roasting generally leaves more sulfur in the calcined product (% in the case of the roaster at mount isa mines) than a sinter plant leaves in the sintered product (about 7% in the case of the electrolytic refini · text under ccbysa licensemolybdenum processing imoaflotation separates the metallic minerals from the gangue this way and in the case of copper/ molybdenum ores separates molybdenite from copper sulphide. the resulting mos 2 concentrate contains between 85% and 92% mos 2. further treatment by acid leaching can be used to dissolve impurities like copper and lead if necessary.how copper is made material, used, processing, stepsconcentrating. the copper ore usually contains a large amount of dirt, clay, and a variety of noncopper bearing minerals. the first step is to remove some of this waste material. this process is called concentrating and is usually done by the flotation method. 3 the ore iscopper copper production tu delftabout 80 % of primary copper production comes from lowgrade or poor sulfide ores. after enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. generally, copper extraction follows the sequence (see figure below) 1. beneficiation by froth flotation of ore to give copper concentratefirst chalcopyrite copper concentrate albion processfirst refractory copper leaching using albion processtm o sable received a parcel of sulphide copper concentrate containing approximately 30% copper (predominantly chalcopyrite, bornite and lesser amounts of chalcocite) % total sulphur % iron o being originally designed as whole ore leach tanks, their sizing was excessive compared to theopportunities for precious metals toll processing andmay 01, · of a copper concentrate processing facility. potential developers could include the producers of concentrate and operators of concentrate processing facilities in other states. nevada is a miningfriendly jurisdiction, and potential locations for a copper concentrate processing facility were identified with access to transportation, energy, and aircopper concentrates cargo handbook the world's largestcopper extraction techniques refers to the methods for obtaining copper from its ores. this conversion consists of a series of chemical, physical, and electrochemical processes. methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. as in all mining operations, the ore must usually be beneficiated (concentrated). to do this, the ore is crushed tcopper teckour customers can be confident in our ability to ensure a longterm, reliable supply of quality copper and molybdenum concentrates. concentrate production is a process where the main metallic compounds of the mines ore are separated and 'concentrated'. this concentrated material isreplacing dichromate with polysaccharide depressant in cuaug 27, · a copper concentrate with a grade of 24.9% cu and a cu recovery of 54.3% was obtained. lead grade in copper concentrate was 5.1%, and less than % of lead was floated during the copper flotation stage, indicating zj 1 depressed galena effectively. close to 80% of g in the bulk concentrate was floated into the copper concentrate.hydrocopper a new method for treating copperhydrocopper can economically recover copper from concentrates and process to a cast copper product. the best utilization of the process is in most cases achieved when the plant is situated at the mine site. higher recoveries are attained by the optimization of the whole operation chain from the mine and the concentrator to the hydrocopper recovering g from copper concentrate via thethe hydrocopper process also enables effi cient recovery of silver and g, which is important because g is often a valuable element in chalcopyritic copper concentrates.the essential prerequisite for good g recovery is a suffi ciently high leaching yield of soluble sulfi des that hinder the dissolution of g.
