The anodes cast from processed blister copper are placed into an aqueous solution of 3–4% copper sulfate and 10–16% sulfuric acid Cathodes are thin rolled sheets of highly pure copper or more commonly these days reusable stainless steel starting sheets (as in the IsaKidd process)
The object of that PCT patent application WO 00/09772 is to provide a copper sulphide concentrate smelting process for producing white metal or blister copper with continuous oxidation of copper sulphide concentrate or matte at the temperature of 1300 C or less without magnetite complications which is applicable for the treatment of copper sulphide concentrate or matte containing SiO 2 with less loss of

The first steps of copper processing are the same for both ores mining and transporting Copper mining is usually performed using open-pit mining in which a series of stepped benches are dug deeper and deeper into the earth over time To remove the ore boring machinery is used to drill holes into the hard rock and explosives are inserted into the drill holes to blast and break the rock
Control of magnetite in slag has also improved with lower %Fe 3 O 4 in slag due to better lime/flux control which in turn helped improve tapping conditions and also maximize available furnace blister capacity Improved control of %S in blister is also a direct result of improved copper in slag control in the FCF and is generally in the 0 2%

The blister copper produced in this process is also laundered to an anode furnace for further refining and casted into anodes The SCF slag is processed for copper-cobalt recovery to produce a copper-cobalt-iron alloy in the cobalt recovery furnace (CRF) The CRF process aims to obtain a final slag of approximately 0 4% copper and 0 2% cobalt which is normally discarded
Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper in the course of removing iron as iron silicate During the smelting process at 1250C copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state Get details
of blister copper in the converter the main target is to remove iron and sulfur After blister copper production the purpose is to remove impurities The primary raw material for smelters is copper sulphide concentrate with 20 30% Cu and the current average is ~25% Cu which is significantly lower than in the beginning of 2000s [11]
cost of copper slag processing machine in australia for Copper slag could be a slag produced throughout copper nutrient smelting slag can be the non-ferrous metals Copper by reflection furnace slag released reverberatory furnace copper slag was employed for your blast furnace blast heating unit copper discharged copper slag
The principal advantage of direct-to-copper smelting is isolation of sulfur dioxide evolution to one furnace of high sulfur dioxide strength gas Its main disadvantage is the large amount of copper-in-slag The products of direct-to-copper flash smelting are copper slag and offgas with different volumes
Molten matte was smelted in converter furnaces to create crude "blister" copper and more slag At this point slag itself contained copper and was recycled rather than discarded Blister copper was further refined in the casting furnaces cast into anodes and shipped to Great Falls where the remaining impurities metals such as gold and silver were removed
gold in copper slag justperuzzi copper slag from gold ore processing ugcnetnic copper processing The extraction of copper from its ores and the prepare the ore for blasting and the broken ore is hauled to the ore dressing plant by truck (at copper and other metals of value (such as gold and silver) the next step is to of the iron react with the flux and form a light fluid layer
For nearly 5 000 years copper was the only metal known to man It remains one of the most used and reused of all metals The demand for copper is due to its good strength and fatigue resistance excellent electrical and thermal conductivity outstanding resistance to corrosion and ease of fabrication
Outotec Direct Blister Flash Smelting for copper With this process blister copper is produced directly in a flash smelting furnace without the need for separate converting phases and ladle transportation This method opens up the possibility to use different raw materials and optimize plant layout while minimizing capital investment
The impure copper produced by the converter is referred to as blister copper because bubbles of sulfur dioxide gas on the surface of the copper look like blisters Blister copper contains 97-98% copper Impurities in blister copper can include gold silver antimony arsenic bismuth iron lead nickel selenium sulfur tellurium and zinc
slag (the chemical interaction) with the refractory material made of aluminium oxide The slag from direct to blister process obtained from Glogow copper smelter was first grinding in a vibratory crusher and then selection of fractions under 0 1 mm was placed in a ceramic corundum crucible in the amount of

Sulfide ores are used to produce a matte (40 – 50 wt % Cu) and a disposal slag (ca 0 5 wt % Cu) In contrast oxide ores are processed directly to impure black copper ( 95 wt % Cu) and to a copper-rich slag The two ore types can be smelted together to produce matte and a slag with low copper content
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98 5% to blister This technological procedure is divided into two phases first slow cooling of slag on the air for 24 hours and then accelerated cooling with water for 48 hours
transform copper sulphide concentrate into blister copper as follows • Wet concentrate drying down to 0 2 wt % moisture • Smelting bone dried concentrate and partial converting to white metal • White metal converting to blister copper • Slag cleaning directed to recover copper from the slag produced during the smelting and partial converting
Apr 16 1991A process for the production of blister copper from high-grade copper matte or similar copper sulphide comprises the steps of solidifying and cooling molten copper matte produced in a primary smelting furnace followed by crushing of the solidified matte if necessary to produce a coarse solid matte less than about fifteen centimeters in size heating a bath smelting reactor to a temperature at which
