  • Microbiological desulfurization of coal

    Jun 26, 1984· Microbiological desulfurization of coal , investigators developed an interest in its used in connection with the beneficiation of high pyrite coal , of a treatment process to enhance the initial rate of microbiological breakdown of the pyritic sulfur content of the coal being treated This enhancement advantageously lowers the required ....

  • CHEMICAL DESULPHURISATION OF SUB

    clean fuels Hence, in order for high sulphur coal to be utilised as clean fuel, the pretreatment processes of sulphur removal from coal have to be effective in order to remove the inorganic (pyrite) and organic sulphur forms The desulphurisation of coal prior to combustion is being carried out either by physical, chemi-cal or biological methods...

  • Final Void Water Quality Enhancement

    Oxidation of pyrite continues to produce acidity and pyrite oxidation has been studied extensively The impetus for this current program of research arose from problems currently being experienced in Stockton Lake, Collie Stockton Lake is a disused open cut coal mine that was closed down in 1957 and it subsequently filled with water...

  • Fuel Contaminants: Volume 4

    With regard to the enhancement of pyrite removal during agglomer- ation, use of sodium metaphosphate will remove 42 percent of the pyritic sulfur from freshly ground minus 48 mesh coal This is the same as that obtained by float-sink analysis suggesting removal of all" the liberated pyrite in the ground coal...

  • Pyrite

    The mineral pyrite (/ ˈ p aɪ r aɪ t /), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide) Pyrite is considered the most common form of sulfide minerals Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's goldThe color has also led to the ....
