Chapter 16 – Solvent Extraction

  title={Chapter 16 – Solvent Extraction},
  author={Michael E. Schlesinger},
Publisher Summary This chapter describes solvent extraction (SX) that purifies and upgrades the pregnant leach solution (PLS) produced by the leaching operation to generate an electrolyte. It is a crucial step in producing high purity electrowon copper from leached ores. The SX process consists of extracting Cu2+ from aqueous PLS into a copper specific organic extractant, separating the aqueous and organic phases by gravity, and then stripping Cu2+ from the organic extractant into high-H2SO4… CONTINUE READING
