BASF produces a complete line of copper solvent extraction reagents, including ketoximes, aldoximes, modified aldoximes and non-modified blends. These reagents and reagent blends allow BASF to supply its customers with the optimum reagent formulation tailored to meet the needs of their specific application.
Moving upstream to the leaching process, BASF has developed LixTRA™, a novel leaching additive aimed primarily at copper heap and dump leach processes. LixTRA™ is a liquid added in small quantities to the mine’s lixiviant and provides faster and higher metal recovery in an environmentally sound and sustainable manner.
The downstream electrowinning process is a key development area for BASF. Today, BASF markets poly-acrylamide based additives as copper smoothing agents.
