Extraction Of Zinc From Smithsonite By Ammonia Leaching

The aim of the study was extraction of zinc from smithsonite by ammonia leaching on cerussite flotation tailings. Initial lead and zinc grades of the ore were 13.31 and 27.86, respectively. As a result of a series of cerussite flotation tests, a lead concentrate containing 63.25 Pb was produced with 82.76 recovery. After that,

Selective Recovery Of Lead From Galenasphalerite By

May 01, 2019 It is difficult to selectively obtain the qualified lead and zinc from the galena-sphalerite ore by using the existing pyrometallurgical process. A novel method by using electro-oxidation in Fe ion solution has been identified which facilitates the selective separation of lead from the galena-sphalerite

Lead Galena Extraction

Lead extraction was not followed further because of the research by Haver 11, who showed lead extraction from a galena concentrate to be 96 to 99 pct in 1 to 2 h at 50 C. Longer times and higher temperatures re sulted in further dissolution of other elements, but did not significantly in crease lead extraction.

Lead Zinc Extraction Processes

The most important lead ore is galena lead sulfide. Other important ores such as cerrusite lead carbonate and anglesite lead sulfate may be regarded as weathered products of galena and they are usually found nearer to the surface. Lead and zinc ores often occur together and for most extraction methods they have to be separated.
