  • Uniformity in sulfur isotope composition in the orogenic

    05/05/2009· The sulfur isotope composition of sulfides (mainly pyrite and arsenopyrite) from gold deposits/prospects of the Dharwar Craton such as Hutti, Hira-Buddini, Uti, Kolar (Chigargunta), Ajjanahalli, and Jonnagiri has a narrow range (δ34S = +1.1 to +7.1‰). Such craton-scale uniformity of the above gold camps is noteworthy, in spite of the wide diversity in host rock compositions and their

  • Sulphur Refining of Gold

    Refining with Sulphur A more speedy method of removing iron, copper, lead and base metals from bullion is to add sulphur to the molten metals. Although gold sulphides may be readily formed in the wet way, they are decomposed into gold and sulphur by merely heating them to a temperature below 300 deg. C. If pure gold is heated strongly with sulphur no combination of the elements appears to take

  • Production and Distribution of Gold in India

    The total in situ reserves of gold ore are estimated at 22.4 million tonnes, with 116.5 tonnes of metal. India’s contribution to world gold production is an insignificant 0.75 per cent. The gold production of South Africa is 60 times, of Canada 22 times and of Australia is 5 time than that of India.

    This paper summarizes the characteristics of epithermal gold deposits and discusses potential ore deposition mechanisms. Epithermal deposits mostly form at shallow crustal levels (<1 km) in subaerial volcanic settings. There are two classes of epithermal deposits which can be discriminated in terms of their geologic environments, alteration mineralogy, and fluid chemistry: (1) low-sulfidation

  • Sulfides, Selenides and Tellurides: rebellious and

    There are also sulfur minerals which contain more than one metal combined with sulfur such as parargyrite (ruby silver), bournonite (peacock copper ore) and tetrahedrite. Most sulfides contain an excess of sulfur more than what their chemical formula would imply. As an example, the chemical formula for galena is PbS. That means there is one atom of sulfur to each atom of lead. However in
