New Extraction Lead Process of beaching PbS Concentration with FeCl₃

Leaching galena concentrate with ferric chloride solution has been made using a orthogonal array to arrange experiments. The main factors of affecting leaching ratio have been found. The optimum process conditions were given.Simultaneously, the fused-salt electrolysis for production metal lead with leaching product lead chloride has been investigated. Experiments show that the new process of the leaching-fused salts electrolysis for making lead is presented.
