The environmental desulfurization of tailings is one approach that has gained much popularity in the last two decades. It was defined as an alternative, integrated tailings management technique that can be accomplished through froth flotation (Benzaazoua et al., 2000, Demers et al., 2009).This method aims to remove sulfide and sulfosalt minerals (flotation concentrate) from gangue minerals (e ...
Read More2020-3-17 High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide (mainly pyrite). Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process,
Read More2018-11-21 For ore with higher arsenic or pyrrhotite, flotation concentrate ore roasting desulfurization or arsenic removal is carried out, and then the calcine is cyanated and leached. Ore with higher carbonaceous minerals, chlorinated and then leached. ...
Read MoreThe invention relates to the desulfurizing method of high-sulphur iron ore power, in particular to the iron ore power recycled by using sulfurous iron ore, pyrites and floatation gangue. When the content of sulphur of the iron ore concentrate, which is mostly magnetite, reaches over 15 percent, by adopting the principle of asynchronous size classification, the iron ore concentrate can reach ...
Read MoreThe effect of pH value on gold extraction for various ore types is shown in Figure 28.4.Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH 9.5–10.0, whereas for some carbonaceous ores, pH value has no apparent effect.

Read MoreThe experiment focused on the bioleaching and desulfurization of pyrite roasting residues by the bacteria for the recovery of Cu, Zn and the magnetic materials. First of all, the study systematically performed XRD, which provided scientific and technique basis for extraction of valuable metals. Subsequently, the effect of the pH, the temperature and the bacterial inoculum volume ratio on the ...
Read MoreToday, one of the most popular methods for gold extraction is the Merrill Crowe process. The process can be summarized as follows: The zinc, cyanide and gold ore are mixed. The gold has an affinity to the zinc and cyanide particles and forms deposits on the surface of the zinc. The zinc and gold particles are then filtered out using a filter ...
