• In Copper Plants, during electrolysis, pure copper is deposited on the cathode plates and impurities which are soluble and fall to the bottom of the cell as anode mud or sludge.
• Gold, like other precious
  metals (Ag, Pt, Pd), is
  extracted from the anode sludge created by the electro-refining process
• Copper concentrates often contain precious metals like Au and Ag.
• Recovery of these metals from anode slime is economically attractive and also it is environmentally
  friendly
• Temperature plays a critical role on dissolution of gold
  from copper anode slime
• Recovery of gold from copper anode slimes is a multi-stages process
• There are more than 650 operating and planned copper mines, 140 smelters and 250 refineries world wide
