Review of metal sulphide precipitation ScienceDirect

1. Introduction. Metal sulphide precipitation is an important process in hydrometallurgical treatment of ores and effluents. Although hydroxide precipitation is widely used in industry for metal removal, there are some advantages to sulphide precipitation, including the lower solubility of metal sulphide precipitates, potential for selective metal removal, fast reaction rates, better settling

Sulfide Wikipedia

Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide. Hydrogen sulfide (H 2 S) and bisulfide (SH −) are the conjugate

Iron(II) sulfide Wikipedia

Some of the hydrogen sulfide will react with metal ions in the water or solid to produce iron or metal sulfides, which are not water-soluble. These metal sulfides, such as iron(II) sulfide, are often black or brown, leading to the color of sludge. Pyrrhotite is a waste product of the Desulfovibrio bacteria, a sulfate reducing bacteria.
