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 1960s.
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 (15% 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 refiniwikipedia · text under ccbysa licensesulfuric acid leaching for capturing value from copperapr 01, 2019· cu was present as cu 2 o, cufeo 2 and cu in slag originating from novel cu process. leaching in acid media was optimized 2 m h 2 so 4, t = 40 °c, 0.26 kw/m 3, 60 min. produced pls was found to be fully integrable with stateofart cu ew process. concentration of as, pb and ni were below the toxicity limits in the treated slag. efficient synchronous extraction of nickel, copper, andjun 18, 2020· jun 18, 2020· obviously, the leaching yield of cu is less than 1% at 400 °c, while the leaching yields of ni and co are 15% and 21%, respectively. this result ismineralogical, geochemical, and leaching study ofmar 16, 2018· abstract historical cuslags located at former industrial sites in poland are exposed to weathering that may trigger release of metallic contaminants to theleaching and recovery of zinc and copper from brass slagsep 01, 2016· zinc dust and slag were used in stoichiometric ratio as cementing agents to remove copper from the leaching solution, within 10 min at 25°c where >99% of coppercited by 99factors affecting the leachability of ni/co/cu slags atthis paper studies the ferric sulphate leaching of converter slag (9% cu) in order to recover cu through a process in which bacteria regenerate the leaching agent. for this purpose, the effect ofcharacteristics and chemical speciation of waste copper slagjan 06, 2021· waste copper slag contains abundant valuable metal element fe, and residual elements such as cu, as, pb, zn, and mo. simply stockpiling or landfilling would waste valuable metal resources and cause contamination due to the leachable harmful elements. in this paper, the hj/t2992007 test and tclp test have been utilized to evaluate the leaching toxicity of waste copper slag, while the
