  • Where was the first solvent extraction plant built?
  • Southern Africa was the site of one of the first large solvent-extraction (SX) plants built, following smaller plants in the North American uranium industry and the Ranchers and Bagdad copper plants in Arizona. The copper Tailings Leach Plant at Nchanga, Zambia, was commissioned in 1973 with a capacity of 2800 m 3 /h.
  • What is solvent extraction (SX)?
  • Introduction Solvent extraction (SX) has been an integral part of the hydrometallurgist's arsenal in southern Africa for many decades. In the 1950s, uranium recovery (as a by-product of gold mining in South Africa) was the first major commercial application of SX technology in the hydrometallurgical industry.
  • How many SX operations are needed for a cobalt recovery plant?
  • Two SX operations are necessary to achieve the desired residual copper concentration suitable for feeding into the cobalt recovery plant (< 100 mg/L). Studies are presently being undertaken to install a copper SX circuit to purify the copper stream, and then to convert the entire tankhouse to conventional EW.
  • What is the organic phase of cobalt SX plant?
  • In the cobalt SX plant, the organic phase is 15 vol.% CYANEX 272 in Shellsol K. Cobalt extraction is achieved in five stages operated at an advance O: A of 1 and pH 5.0 to 5.3. Scrubbing of co-extracted magnesium is with 40 g/L cobalt solution in two stages operated at an O: A of 50.
