    Much of the hydrogen sulfide will react with metal ions in the water to produce metal sulfides. These metal sulfides, such as ferrous sulfide (FeS), are insoluble and often black or brown, leading to the dark color of sludge. Thus, the black color of sludge on a pond is due to metal sulfides that result from the action of sulfate-reducing bacteria. Antimony sulfide as an energy storage material with remarkable theoretical capacity has captured the attention of several researchers, but it has disadvantages such as volume expansion, polysulfide dissolution, and sluggish kinetics. By utilizing the oxygen functional groups in phenolic resin, engineering th.

    Cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms. These concentrated ore deposits are considered low grade because of the economic costs associated with processing, but they can be separated economically when prices for these metals rise on the open market. The biological oxidation of sulfides and sulfur-containing compounds is a widely practiced industrial process. The use of sulfur oxidizing bacteria to treat hydrogen sulfide present in air exhaust or vent air streams is a commercial process practiced by a number of companies. 2 It might seem obvious that a simple solution would be to strip all the sulfide out of the aqueous phase into the.

    Incorporating different materials, such as metal sulfides, with metal–organic frameworks (MOFs) to develop MOF-based multifunctional composites with enhanced performance is an important area of research. However, the intrinsically high interfacial energy barrier .   Mining residues from mining activities are dumped as waste rock or as tailings, which are metal-degraded materials from ore processing. Both kinds of dumps often contain sulfide minerals such as pyrite (FeS 2) or pyrrhotite (Fe 1− x S, x = 0 to ) and release acidic metal-rich waters known as acid mine drainage (AMD)/acid rock drainage (ARD) because of chemical and microbial sulfide.

Generally, bacteria, fungi or other microorganisms convert dissolved sulfate ions into reduced sulfides using certain enzymes and under different conditions, and subsequently, the sulfide anions react with soluble metal cations to. Hydrogen sulfide is the chemical compound with the formula H 2 is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs.

It is very poisonous, corrosive, and flammable. Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic.

and Brierley, C.L. Oxidizing metal sulfides to sulfate via contact between bacteria and mineral (direct) and oxidizing Fe 2+ to Fe 3+ or/and S o to SO4 (without contact: indirect) are the main mechanisms of metal. Abstract Diverse numbers of iron‐ and sulfur‐oxidizing microbes have been found in submarine hydrothermal deposits.

They have played a prominent role in weathering of seafloor sulfide. Considering the wide distribution of iron‐sulfide minerals on the ocean floor, these widespread bacteria might contribute significantly to turnover of iron and sulfur, as well as carbon fixation in deep‐sea habitats other than hydrothermal vent fields, such as marine sediments making microbial mineral oxidation a much more common process.

The microbial oxidation process occurs at the cell membrane of the bacteria. The electrons pass into the cells and are used in biochemical processes to produce energy for the bacteria while reducing oxygen to water.

The critical reaction is the oxidation of sulfide by ferric iron. Microbial corrosion, primarily due to SRB, is a significant cause of the corrosion of underground structures, especially pipelines. More detailed reviews of the electrochemical process are to be found in books by Shrier (),Evans (),and Uhlig ().

In general, when a metal is immersed in water, the metal dissolves at certain sites.Sulfate-reducing bacteria (SRB) can affect metal mobility either directly by reductive transformation of metal ions, e.g., uranium, into their insoluble forms or indirectly by formation of metal sulfides.

This study evaluated in situ and biostimulated activity of SRB in groundwater-influenced soils from a creek bank contaminated with heavy metals and radionuclides within the former uranium.The microbial oxidation process occurs at the cell membrane of the bacteria.

The electrons pass into the cells and are used in biochemical processes to produce energy for the bacteria while reducing oxygen to water. The critical reaction is the oxidation of sulfide by ferric iron. The main role of the bacterial step is the regeneration of this.
