mineral processing lead recovery from galena using ferric chloride

Ferric Chloride Thiourea & Brine Leaching to Recover . Ferric Chloride. Because Wong extensively investigated extraction of lead from galena concentrates, only minimal effort was expended to investigate the FeCl3 leaching phase of the process. However, because Wong’s work was with a high-grade galena concentrate (74 pct Pb), some research was conducted to obtain maximum silver chloridization.



Ferric Chloride Leaching The method consists of leaching galena concentrate with ferric chloride-sodium chloride solution, cooling the solution to crystallize PbCl2, electrolyzing the lead chloride in a molten-salt bath to produce lead metal and chlorine and using the chlorine to regenerate ferric chloride in the leaching solution, 2FeCl2 + Cl2 → 2FeCl2.



leaching galena lead Ferric chloride leaching is a potentially attractive method of processing lead concentrates, and many studies have been carried out on the kinetics of dissolution of galena (PbS). Get price Agitation leaching recovery of lead and zinc from complex .

Electrogenerative leaching of galena with ferric chloride . Ferric chloride leaching is a potentially attractive method of processing lead concentrates, and many studies have been carried out on the kinetics of dissolution of galena (PbS).



How to Produce Pure Lead from Galena Concentrates Several galena leaching processes have been investigated, including processes using ferric chloride, ferric sulfate, nitric acid, and ammonium acetate solutions. The leached PbCl2 and PbSO4 salts have a very limited solubility in aqueous solution, making aqueous electrolysis difficult.

Ferric Chloride Leaching The galena concentrate used in ferric chloride leaching was a concentrate from southeastern Missouri. Analysis of the concentrate is shown in Table 1. The lead concentrate contained primarily galena and small amounts of chalcopyrite, sphalerite, marcasite, and siegenite. The gangue material contained a small concentration of dolomite.
