innovations in copper mining extraction producingprior to the development of the solvent extractionelectrowinning (sx/ew) process in 59 (see copper the green metal), the only way to recover copper from an acid solution was by a process called cementation. in this process, copper was in effect "traded" for iron by contacting the copperbatu hijau copperg mine mining technology mining and milling. batu hijau is an openpit mine. ore is transported to the primary crushers using ph 4100 electric mining shovels and a fleet of 2tcapacity 793c mechanicaldrive haul trucks. the mine typically handles around 600,t/d of ore and waste, the ore grading an average 0.49% copper and 0.39g/t g.innovations introduction to copper mining extractionthe copper agethe bronze agethe middle ages and laterminingalso in this issuepredynastic egyptians knew copper very well. in hieroglyphic writing the symbol used to denote eternal life, the ankh, was also used to represent copper. the greek philosophers later adopted the symbol, slightly modified, as . the connection between eternal durability and the lifetime costeffectiveness of copper and its alloys is surely not coincidental! the egyptians obtained most of their copper from the red sea hills, but copper predates ancient egypt by several millennia, and it is now known that an the leaching and adsorption behaviour of g orestelfer oxide ore, which was not found to be pregrobbing, enhanced g extraction was observed at low cyanide concentrations, but not at high concentrations, as the g was completely extracted by cyanide alone. the flotation feed and copper concentrate showed an enhancement in g extraction due to the activated carbonrecovery of silver, g, and lead from a complex sulfiderecovery of silver, g, and lead from a complex sulfide ore using ferric chloride, thiourea, and brine leach solutions by r. g. sandberg 1 and j. l. huiatt 2 abstract the bureau of mines investigated a hydrometallurgical procedure to re­ cover g, silver, and byproduct lead from a complex leadzinc sulfide ore.g extraction overviewconcentrationhistorytypes of oreleachingrefractory g processesg smeltingg refining and parting

gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. however, froth flotation processes may also be used to concentrate the g. in some cases, particularly when the g is present in the ore as discrete coarse particles, a gravity concentrate can be directly smeltedto for · text under ccbysa licensesmelting and roasting ores to recover g, silver andthe process works best when the ore is crushed to small pieces before roasting. additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. once the ores are fully roasted, and the sulfur is driven off, the extraction of the g or silver from the ore is not especially difficult.extraction of copper and zinc chemistry, class may , · extraction of copper. it is mainly extracted from copper pyrites (cufes 2). the sulphide ore is usually of very low grade and contains iron sulphide, gangue and smaller quantities of arsenic, antimony, selenium tellurium, silver, g and platinum. the various steps involved in the extractionextraction of copper from the ore youtubeconversion of cu(ii) ion into copper metal via electrolysisgcopper ores sciencedirectjan 01, · today, flotation is commonly used in the processing of primary copperg ores to produce a copper concentrate containing g as a coproduct, where the g is recovered as a byproduct of copper smelting and refining (la brooy, 92). the g is usually discrete and either free, associated with coppercited by 55copper geoscience australiathe ore is then ground finely before the copperbearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copperbatu hijau copperg mine mining technology miningmining and milling. batu hijau is an openpit mine. ore is transported to the primary crushers using ph 4100 electric mining shovels and a fleet of 2tcapacity 793c mechanicaldrive haul trucks. the mine typically handles around 600,t/d of ore and waste, the ore grading an average 0.49% copper and 0.39g/t g.extract copper and g from lowgrade ores fla mechanochemical process called rapid oxidative leach (rol) is the gamechanger for miners struggling to extract copper and g from lowgrade ores. the technology leaches 9799 percent copper directly onsite in six to eight hours, from concentrates as low as 5 percent copper.

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
