Zinc Mining Process - m.ytmineral

Zinc Mining Process ... Smithsonite can be directly recovered by the flotation process with advanced xanthate or collector of fatty acid, but the selectivity is very poor. In the industrial production, the amine collector (octadecylamine or mixed amine) is often used to the extraction of smithsonite after the sodium sulfide treatment. ...

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

2018-6-1  Smithsonite is a readily dissolvable carbonate mineral that is naturally hydrophilic, making recovery of this ore by flotation difficult. The flotation results showed that conditioning with only sodium sulfide (Na 2 S) did not successfully allow the smithsonite samples to float, whereas treatment with a combination of S(II), Pb(II) and xanthate (with Na 2 S as the sulfurizing reagent, lead ...

Zinc removal from hard, circum-neutral mine waters using

2000-3-1  The work summarised in the Eh–pH diagram of Hem (1972) indicates that zinc can form a stable carbonate mineral (smithsonite, ZnCO 3) over a narrow pH range (approximately pH 7.5–8.0) in natural waters.Therefore, if the correct physical and chemical conditions could be achieved, smithsonite precipitation could offer a process for removing zinc from net-alkaline mine waters.
