The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product Each process consists of several steps in which unwanted materials are physically or chemically removed and the concentration of copper is progressively increasedBassemer’s Process or Bessimerisation The instrument is lined with acidic and basic lining Impurities are converted into Oxide’s foxitsoftwareSb Zn Ag Alloy distillation == Ag obtained but contains Pb impurity II For evaluation only

The process of recycling copper is roughly the same as is used to extract copper but requires fewer steps High purity scrap copper is melted in a furnace and then reduced and cast into billets and ingots lower purity scrap is refined by electroplating in a bath of sulfuric acid produced from smelting copper ores and matte conversion to blister copper contain an appreciable amount Tof copper arising mainly from partially dissolved copper and

The old traditional process is based on roasting smelting in reverbatory furnaces or for production of blister copper which is further refined to cathode copper process the ore is leached with ammonia or sulfuric acid to extract the copperThe converted copper known as blister copper is recovered The blister copper then undergoes fire refining Air and natural gas are blown through the copper to remove any remaining sulfur and oxygen The copper is cast into copper anodes and placed in an electrolytic cell In the electrolytic process called electrowinning the copper
