Direct smelting of sulphidic copper concentrates to blister copper involves clear benefits in the smelting operation in particular if modern flash smelting technologies are used A simplified

In fire refining blister copper is usually mixed with flux and charged into the furnace which is maintained at 1100 C 2010 F Air is blown through the molten mixture to oxidize the copper and any remaining impurities The impurities are removed as slag The remaining copper oxide is then subjected to a reducing atmosphere to form purer copper

Sulfidic copper ores are too dilute for direct smelting Smelting these materials would require too Typical equipment for crushing to about 20 cm are gyratory and cone crushers Then wet grinding 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 Another

Copper is mined from a variety of ores often containing less than one percent copper This copper is typically in the form of mineral compounds with sulfur iron arsenic and tin To facilitate transportation to smelters concentration to about 30 percent copper content is accomplished at the mine sites via crushing grinding and flotation

Blister copper plant manufacturer used copper blister mining equipement eduorg blister copper plant manufacturer heavy industry is specialized in the design manufacture and supply of crushing equipment used in mining industry Chat Online blister copper

Uranium ore processing copper blister There are forty years of manufacturing history with three major production bases over 160 senior RampD engineers and 600 large and medium sized digital processing equipment The first line technicians and professional after sales service personnel up to 2 300 and 200 respectively

Copper slag flotation plant copper slag flotation plant XSM excellent mining crushing machinery products or production line design the company is committed to building the Chinese brand mine crushing and processing machinery mainly crusher mill sand making our products copper slag flotation plant in than one hundred of the worldsales of countries and regions

The present invention provides a process for direct to blister copper flash smelting where the energy balance of the smelting process and decreasing the overall impurity content of volatile components in controlled by roasting at least part of the copper concentrate together with flue dust before the smelting step The present invention further provides a use calcine obtained by the roasting

With the elimina tion of impurities mainly the sulfur as S02 and iron in the slag the matte is converted to the blister copper product that consists of about 98 to 99 percent copper Pouring of the blister copper like the slag is done through the mouth of the converter Figure 9

The primary smelter and refinery plant uses concentrate as a raw material produces copper cathodes sulphuric acid and precious metals and discards slag and offgases Up to the production 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

Conversion of Matte into Blister Copper impure copper Air is blown through the molten matte which converts ironII sulfide to ironII oxide and sulfur dioxide 2FeS 3O 2 2FeO 2SO 2g IronII oxide FeO slag is skimmed off Relatively pure copperI sulfide Cu

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

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

Thus copper concentrate can be flash smelted in a first operation to matte grade of about 55 while producing a slag which can be discarded the matte can be granulated ground and smelted in a second flash melter to yield white metal or blister copper with the slag from the second flash smelter being returned to the first smelter operation

Copper is an ancient metal it was produced about 4000 BC It can be readily obtained from oxide ores by reduction or from sulfide ores by conversion a unique reaction whereby molten copper sulfide is directly converted to metal by blowing air 1 Cu2S O2 Cu SO2 At present about 80 of copper is produced by this route It was not too

Jun 01 2009 The heaviest molten phase obtained is periodically tapped from the furnace and sent to a converter for its conversion to blister copper 2 Slag is subjected to coolingsolidification crushing grinding and flotation to obtain a 30 to 60 Cu concentrate Rao and Nayak 1992

The blister copper produced by this process is 99 pure copper The name blister copper comes from the fact that this final process produces bubbles of sulfur dioxide on the surface of the copper The blister copper is cast into anodes ready for electrolytic
