Extraction of Zinc from Smithsonite by Ammonia Leaching

2020-1-8  Characterization studies showed that the run-of mine ore is rich in oxide minerals, cerussite (PbCO 3) and smithsonite (ZnCO 3). 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

Smithsonite: Mineral information, data and localities.

Smithsonite is often found as a secondary mineral in the oxidation zone of zinc ore deposits. It can also be observed in sedimentary deposits and as a direct oxidation product of sphalerite. Visit gemdat.org for gemological information about Smithsonite.

Flotation separation of smithsonite (ZnCO 3) from calcite (CaCO 3) is not commonly satisfied using traditional fatty acids, and thus, more selective collectors are required.In this regard, a new collector, N-hexadecanoylglycine (C16Gly) was used to selectively collect ZnCO 3 from CaCO 3 in this work. The flotation selectivity of C16Gly was predicted by DFT calculations.
