Sulfating roast is generally used for processing copper/cobalt concentrates in combination with electrowinning. The copper sulfide is transformed into water-soluble copper sulfate and the iron sulfide into insoluble iron oxide. Standard sulfating roasters run with a slurry feed and do not require a waste-heat boiler system in the off-gas stream.

Abstract. Present design of concentrating plants is briefly dealt with, emphasizing the different factors which seem to be most important in these days of high labour costs and reduced availability of low-cost energy. Such items as autogenous and semi-autogenous grinding, two-stage classification, large flotation cells, pressure filtration, etc ...
The copper concentrate processing fee for that year was US$56 per ton and 5.6 cents per pound. Since 2016, the processing fees of copper concentrates have fallen year after year. A source from a Chinese smelting company revealed that in view of the current spot processing fees, the results were better than expected."
with such equipment as high pressure, high temperature, acid resistant autoclaves. This problem can be avoided by heap leaching, but the long retention times cause an in-process inventory which may exceed the cost of processing equipment. From the capital expense standpoint, the resi dence time is extremely critical, since long retention
Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the …
Xinhai is the earliest company who put forward the turnkey solution for mineral processing plant (EPC + M+O) in China, including mining technology consulting, mineral dressing test, mine design, equipment manufacture and procurement, engineering construction, installation & debugging, worker training, standard reached and operating management.
Copper Processing Plant. Copper is mainly used in electrical equipment manufacturing, construction, such as roofing and plumbing, industrial material, such as thermal …
The effectivity of present copper smelting technologies have their roots in industrial and laboratory-scale experience accumulated over the past decades. Since early '60s, the tools for improving the processing conditions and smelting vessel design included scale modelling and manual computing of homogeneous multicomponent equilibria. The …
Copper Concentrate. Typically, copper concentrates contain 20–30% Cu and up to 5% Zn. Copper flotation tailings are activated with copper sulfate and zinc minerals floated …
Production equipment can be controlled and checked from a control centre by monitoring and recording the parameters of the electrolysis process. Therefore, quality of the produced copper cathodes is always kept at a level to our customers' satisfaction. Eti Bakir Co. produces 42,000 mt electrolytic copper and 200,000 mt sulphuric acids per year.
The copper concentrate is first placed in the smelting furnace to be heated up to 1260 °C and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. ... Proper maintenance can extend the …
The rotary drying system consists of a final concentrate thickener to dewater the slurry to about 60%-70% solids; a vacuum filter (disc or drum) with the …
In the 70 year history of the Flash Smelting process for sulphide concentrates [2], significant equipment development was needed in the completely new smelting concept, and specifically the novel smelting furnace (FSF) and its key equipment. Already from beginning, the very low use of external fuel and a superb sulphur fixation were evident.
Copper concentrator process and production processes mainly include three processes: crushing, grinding, and beneficiation. The effect of flotation extraction is better than …
Direct to blister copper process is the technology that is used to directly produce copper by using copper sulfide concentrate in a single equipment (Fig. 1 ). Some special copper ores, e.g., chalcocite (Cu 2 S) and bornite (Cu 5 FeS 4 ), have high copper content and low iron content, the grade of their concentrate is similar to that of …

Copper ore beneficiation process The principle of priority flotation process is: crushing and screening→grinding and classification→priority flotation of copper …
The process involves four steps: Production of a gravity concentrate from the mill circuit. Intensive cyanide leaching of the concentrate in an InLine Leach Reactor. Selective absorption of the gold onto Aurix® resin. Stripping and electrowinning of the gold from the Aurix® resin to give gold dore.
Copper smelters can be classified as integrated or custom. Integrated smelters, as the name suggests, process concentrates from their own mine(s) to anodes and (usually) cathodes. Custom smelters process concentrates from non-related entities (also called custom mines). However, the lines of distinction have become blurred.
JXSC's vast experience in processing copper in its varied forms improves copper ore processing plants through the production of optimized copper processors and extractors. ... The size of final concentrate affects the use of the grinding equipment. The concentrate is smaller than 1mm, we need to use a ball mill. While the concentrate is ...
The processing technology of the copper ore beneficiation plant includes flotation, microbial leaching, segregation and beneficiation, etc. Single sulfide ore is …
Valves and pumps for copper concentrates production Valmet . The copper concentrate is transported to a smelter where it is purified at high temperatures. Pyro processing begins with a smelting furnace where the concentrate is converted into molten liquid. The temperatures at this phase are as high as 1200 ᵒC (2300 ᵒF).
The Inc concentrate roasting and sulphur dioxide gas processing plants have undergone many chang over the years. This paper describes the processes and equipment currently used for concentrate r astlng, S02 gas cooling and cleaning, mercury removal, sulphuric acid production, liquid S02 produ Ion, and taM gas S02 scrubbing.
IN PROCESSING COPPER ORES In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia [4]) owing to the exhaustion of rich copper resources. The flowsheet of processing copper ores is
