Extraction of Chromium from Chromite Ore

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, enstatite, chromite, magnetite, hematite, and olivine. Examination of

flotation of chromite ore - allstartheatre

The forth flotation, chromite ore recovery process of the present invention can be employed for the recovery of chromium values from any grade of chromite bearing ore. However, the method of the invention is particularly useful in recovering chromite from such low-grade chromite ore as those found in the Stillwater Complex in Montana, USA.
