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, enstaMeer bekijken op 911metallurgist
  • Process for extracting chromium from chromium

    15-6-1976· The commonest of these ores is chromite, a natural oxide of iron and chromium, which in some cases contains oxides of magnesium, aluminum and silicon. Chromium is generally extracted from its ores by oxidation in the form of chromate, in which state its valence is six. The product of this reaction is then treated to extract the chromate.
