Sustainability Profile
LIX^® HS for copper solvent extraction

Performance Benefits 

• LIX® HS products can be flexibly composed out of up-to 3 components, allowing for formulations to be customized to the individual customer’s process requirements 
  • Their broad operating parameters make them capable on both low- and high-grade ores as well as being suitable for arsenic-containing leach solutions
  • Their fast kinetics offer rapid copper uptake and copper stripping
  • Their high selectivity targets copper over other metals (e. g. Fe, Co, Ni, As, Mn) and also leads to very high iron rejection
  • Their low viscosity and density allows them to operate well at high reagent concentrations and low temperatures
  • They provide clean phase separation, low crud formation, have an excellent net copper transfer, support low entrainment and low transfer of contaminants
  • Together with an excellent chemical stability the LIX® HS products leads to solvent extraction operations running at maximum efficiency and low operating cost

• Comparing LIX® HS blends to modified aldoximes, the above-mentioned benefits lead to lower consumption rates (and/or higher recovery) and better selectivity
