Solvent extraction in the primary and secondary

2009-8-27  Solvent extraction in the primary and secondary processing of zinc using D2EHPA; zinc was stripped with 1 MH2SO4and ironwas periodically removed from the organic phase bytreatment with HCI. It was reported, however, that HCIstripping introduced partial degradation of the extractant,and a reductive stripping process for iron was underdevelopment.
