DOI: 10.1007/s11120-021-00882-8
Abstract: Sulphide is proposed to have influenced the evolution of primary stages of oxygenic photosynthesis in cyanobacteria. However, sulphide is toxic to most of the species of this phylum, except for some sulphide-tolerant species showing various… read more here.

DOI: 10.1016/j.clay.2017.07.003
Abstract: Abstract Bentonite clays will be used as barriers in geological repositories for radioactive wastes. Anoxic conditions will prevail in such repositories, and the presence of sulphide-producing bacteria in commercial bentonites and deep groundwater environments is… read more here.

DOI: 10.1016/j.colsurfa.2019.123655
Abstract: Abstract Froth flotation is a widely used process for the beneficiation of complex sulphide ores. Thiol collectors (mostly xanthates) are usually effective collectors for sulphide minerals but may have a low selectivity between different sulphide… read more here.

DOI: 10.5277/ppmp170207
Abstract: Froth flotation of copper-zinc-lead ores is a complex process based on similar metallurgy processing and strong interactions between chalcopyrite and sphalerite. These types of ores represent 15% of the world production and 7.5% of copper… read more here.
