    sulfur lowers ph in gold leaching

    The presence of bacteria lowers the pH and hence facilitates calcium dissolution. Iron ores generally contain alumina, silica, sulfur, and phosphorous as the main gangue minerals. At pH 7, leaching for 5 days, at inoculums size of 20%, Ronini obtained an optimum recovery of 79% of the iron content in the slimes. Bacterial leaching of . Get Price

    2019 5 18 · If this was reagent grade elemental sulphur then it can be fairly hydrophobic and therefore very slow to react. If you want to observe it in the lab then it helps if the pH is elevated and a surfactant to disperse the sulfur may also assist. I work for a gold mine using the Biox process for oxidation of gold bearing pyrite/arsenopyrite.
