  • Arsenic Pyrite Gold Extraction by Alkaline Leaching Oxidation

    Arsenic Pyrite Gold Extraction by Alkaline Leaching Oxidation

    Gold mining uncovers more and more hydrothermal deposits in which gold mineralization is associated with sulfides and other compounds of base metals, arsenic, antimony, or tellurium. This type of mineralization frequently makes gold recovery difficult by conventional techniques, such as amalgamation, gravity separation, or direct cyanidation.

    Arsenic trioxide and underground issues at Giant Mine

    Arsenic trioxide waste was created during mining operations. When the arsenopyrite ore was roasted to release the gold, arsenic was also released as a gas, arsenic dioxide. As the gas cooled, it changed to a solid state and became arsenic trioxide dust.
