Abstract a new route for the extraction of gold and silver from three different galena-sphalerite-pyrite flotation middlings bulk scavenger tailing, zinc middling and pyrite middling assaying 2.3, 2.6 and 1.5 gt au and 82, 53 and 27 gt ag, respectively, and containing different proportions of the sulphide minerals was investigated.Each sample was pressure oxidised for 4 h at 200c or 220.Get Price
The new leaching technology, i.E.Acid leaching under pressure, that is used on high iron containing sphalerite, is introduced.The test results show the zinc leached rate in first step is more than 95, and it is more than 98 on the second step, so the two step leaching process can achieve the following targets zinc and iron leached selectivity and reduce the acidity of the leaching solution.Get Price
In the lower part of the deposit, -1200 m, the liberation degree of galena is decreasing and the one of chalcopyrite increasing compared to the reference ore.These characteristics of the future feed of the plant suggest to modify the flowsheet to a copper flotation followed by lead and zinc flotations.Get Price
A major advantage of the sherritt zinc pressure leach process is the conversion of sulphide sulphur in zinc concentrate to elemental sulphur during pressure leaching.Elemental sulphur can be recovered as a marketable byproduct by flotation of the leach residue, and melting and filtration of the sulphur flotation concentrate.The behaviour and deportment of sulphur.Get Price
