    01.07.2017· The sulfide minerals represent higher temperatures and a slightly deeper setting than the sulfate minerals, which reflect the oxygen-rich environment near the Earth's surface. Sulfides occur as primary accessory minerals in many different igneous rocks and in deep hydrothermal deposits that are closely related to igneous intrusions.

    01.04.2017· Sulfide minerals can also form through the activities of a group of bacteria known as dissimilatory sulfate-reducing prokaryotes (SRP) (see Rickard et al. 2017 this issue). The SRP occur in anaerobic environments that include lakes, swamps, soils and marine sediments. As part of their metabolic processes, these organisms reduce sulfate ions to sulfide which can react with any

    Electronic Structure and Surfaces of Sulfide Minerals

    Natural sulfide minerals commonly contain lattice impurities, such as Fe-bearing sphalerite, Ag-bearing galena, and Au-bearing pyrite. In this chapter the effects of lattice impurity on lattice constants, semiconducting and electronic properties, the frontier orbital coefficient, and floatability of sulfide minerals have been studied. The occurrences and correlation of gold (Au) and arsenic

    Sulfide Minerals in Hydrothermal Deposits Elements

    Sulfide minerals in hydrothermal deposits are the primary economic source of metals used by society, which occur as major, minor and trace elements. Sulfides also play a key role during magmatic crystallization in concentrating metals that subsequently may (or may not) be supplied to hydrothermal fluids. Precipitation of sulfides that themselves may have little economic value, like pyrite, may
