Electrochemical kinetics on bulk concentrate separation of pyrite and galena

摘要

The electrochemical reduction kinetics of lead butyl - xanthate on galena surface and butyl - dix - anthogen on pyrite surface has been investigated. The results showed that overpotentials of lead butyl - xanthate on galena surface and butyl - dixanthogen on pyrite surface were 308 mV and 151 mV respectively, and ex - change current densities were 1.1 × 10~-5 A/m~2 and 1.28 × 10~-2 and 1.28 ×10~-2 A/m~2 respectively.
