    Their rumen is the site of high sulfide generation, and the interaction of molybdenum with sulfur results in the formation of thiomolybdates. Tetrathiomolybdate, a thiomolybdate with four sulfur atoms, can form complexes with copper preventing its absorption and blocking the activity of copperdependent enzymes. (More information) In humans, tetrathiomolybdate therapy has been developed for

  • Copper ores Danafloat Home

    The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist
