    Ore SamplesChromite Ore ProcessingChromium Ore MetallurgyConclusionsChemical analyses of the ores used for the research are shown in table 1. The calculated chromite heads in subsequent tables, although not in perfect agreement with head assays, show that the tests are within experimental error and the assay variations on the feed materials. A petrographic examination of the Auburn ore showed that it contains major amounts of epidote, chlorite, and serpentine, with minor amounts of calcite, ensta在911metallurgist上查看更多信息
  • A clean and efficient leaching process for chromite ore

    2014-6-1 · Sodium chromate is then leached from the roasted mass, and the leach residue is recycled as backfill material for subsequent roasting or detoxified to reduce the chromium (VI) content before land fill (Antony et al., 2006). However, this process is only applicable to high-grade chromite ores with silica content less than 1%.
