The problems with processing sulfide ores by the normal methods and the fact that most of those problems can be removed by first roasting the ore, led to the development of a variety of ore roasting systems that were installed in the mills of that day
A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here Conventional Copper Extraction Conventionally, copper is recovered by a pyrometallurgical process known as smelting In this process copper ore is mined, crushed, ground, concentrated, smelted and refined
The final step in processing sulfide ore copper from the smelter is to make high purity copper cathod 8 Copper Products & Many Us Copper cathodes are pure copper produced from the processing of copper or However, cathodes are not in the final form of usage as copper materials 9 Uses of Copper
Copper-Lead-Zinc or , Other factors related to the specific copper and lead mineral processing characteristics must be considered when deciding on which copper or lead mineral will be floated from the other, for instance relative mineral flotation kinetics , copper depression can be achieved by using sodium sulphide, hydrosulfite, lime .
ore flux \ m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux It was blown for several hours by foot or hand bellows By the end of the smelt the copper had separated from the slag, which was tapped off
The product from the SART process is a copper/silver sulphide precipitate, which is thickened, filtered and dried and then sold for copper smelting Graphical abstract Flowsheet of Anglo Asian Mining’s process for treatment of gold/copper ore with heap leaching, CIX and SART technology
Double decomposition Copper sulphate can be used to separate Copper from Nickel in a sulphide ore or Copper from Fe in Cu -Fe sulphide ore CuSO4 solution can also be used for removing Pb, Zn, and Fe from copper sulphide or
A protocol was developed for extracting copper from kupferschiefer ore Preliminary leaching with water removed most of the halite present • Secondary leaching with sulfuric acid solubilized carbonate minerals and copper
