Jul 03 2013EXTRACTIVE METALLURGY OF COPPER Copper is mostly extracted from ores containing copper sulphides copper oxides or copper carbonates Copper ores are generally poor and contain between 1 5 and 5% copper Therefore commercial extraction of copper involves several dressing operations before the smelting stage 71
Nickel the free encyclopedia Nickel is a chemical element with symbol Ni and atomic number 28 It is a silvery-white lustrous Radioactive nickel-56 is produced by the silicon burning process and later set free in large quantities during type Ia supernovae
Sulfide Ores Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation From Extractive Metallurgy of Nickel Cobalt and Platinum Group Metals 2011
Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes The cathode plates are coated with graphite in order to remove depositing copper The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity
Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source local environmental regulations and other factors
Metal ores are generally oxides sulfides silicates native metals such as copper or noble metals such as gold Ores must be processed to extract the elements of interest from the waste rock Ore bodies are formed by a variety of geological processes generally referred to as ore genesis
Beginning in the mid 1980s a new technology commonly known as the leach-solvent extraction-electrowinning process or SX/EW Process was widely adopted This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes Today worldwide approximately 20% of all copper produced is produced by this is process
Copper sulphate can be used to separate Copper from Nickel in a sulphide ore or Copper from Fe in Cu -Fe sulphide ore CuSO 4 solution can also be used for removing Pb Zn and Fe from copper sulphide ores In presence of oxidizing agents Ferric ion Ferric sulphate or chloride react with metal sulphides liberating elemental sulphur e g
