    The first large-scale copper SX plant in the world was commissioned at the Nchanga Tailings Leach Plant (TLP) in Zambia in 1974, with a daily production of 200 t Cu cathode (Holmes et al., 1976). The mixer–settlers, configured as four trains each comprising three extraction and two stripping (3E–2S) stages, are long and narrow (aspect ratio of 2.9:1)

    copper and cobalt while rejecting iron as hematite. The autoclave discharge contains 60 g/l Cu and the acid tenor is minimised to 5 g/l, allowing the liquor to be purified directly by SX. The high-tenor SX1 circuit removes the bulk of the copper, the extraction of 50 g/l Cu generating a raffinate containing ~80 g/l H 2SO 4. This acid is used to leach copper from the

  • Copper Mining and Extraction: Oxide Ores

    After solvent extraction using organic solvents, the copper ions are stripped from the solution with a strong acid and leave a blue solution with a high copper content.This is called the ‘rich electrolyte’. 4. The electrowinning plant uses electrolysis to collect copper onto steel cathodes. Inert lead anodes are used.
