Simulation of pyrite oxidation in fresh mine tailings

 · The chemical composition of the solid tailings was also determined The field data were compared to predictions from simulations of pyrite oxidation using a 1 D numerical model The simulations estimates of the amount of Fe and S released over a seven year period 52 kg and 178 kg respectively were in reasonably good agreement with those obtained by

Sulphide oxidation and geochemical processes in mine tailings

Pyrite grains were collected from a profile through the pyrite rich tailings at the Kristineberg mine in Northern Sweden At each spot hit by the laser the surface layer was analysed in the first shot and a second shot on the same spot indicated the chemical composition of the pyrite immediately below The crater diameter for a laser shot is known and by estimating the crater

Treatment of Old Pyrite Flotation Tailings for Recovery of

A sample of old pyrite flotation tailings from the concentrator contained % sulfidic iron % sulfidic sulfur % copper % zinc and g/t gold Pyrite was the main sulfide mineral 31% The gold recovery from the unoxidized flotation tailings was 50% Recently it has been proposed to recover copper and zinc from this waste by the treatment with sulfuric acid

BG Pyrite oxidization accelerates bacterial carbon

For each tailing sample the relative abundances of the sequences assigned to a given taxonomic unit were calculated for each of three subsamples and the average value was then used to represent the relative abundance of each tailing sample Download Bacterial communities in mine tailings under FeS 2 addition A total of 220 877 usable sequences

Pyrite Tailings Recovery by Flotation

 · Pyrite has long been used as a source of sulphur and its recovery as a by product from the flotation of certain base metal ores is a well established practice Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite In many instances these tailings can be treated to yield pyrite
