Solvent Extraction Training SX Course

Key Facts About Copper Solvent Extraction

  • First plant in 1968, now practiced on 6 continents
  • Most plants produce LME quality copper
  • Small (~ 1000 T / yr) to large.
  • Very simple (1 train at 2E,1S leaching one type ore)
  • Complex (4 trains at 2E,2E,1W,1S leaching antacamite and chalcocite)
  • Very complex (4 SX plants, 3 tankhouses, dump leach, heap leach, concentrate leach, oxide and sulfide ores)
  • Six types of leaching
    Heap, dump, in situ, vat, agitation, autoclave

Copper Recovery Process Composed of 3 Individual Processes

Leaching
– Puts copper in an acid water solution
Solvent Extraction
– Transfer copper from leach to electrowinning
– Transfer acid from electrowinning to leach
Electrowinning
– Transfers copper from solution to metal

Electrolytic Refining

The list of pure non-ferrous metals so widely used in modern industry includes many that are produced by electrolytic means, such as copper, zinc, nickel, aluminum, magnesium, lead, sodium, cadmium, calcium and many others. In the case of some metals, ordinary fire or chemical methods of production are important, but in others, 100 per cent of the
