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.

Chromite - Wikipedia

Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.

How to Recover Chromite

The chromite content varied in the different size fractions and is listed in table 4. Chromite gram analyses ranged from 60 to 70 pct Cr2O3. Liberation was measured by grain counting and was performed on all the size fractions. This ore began to show chromite liberation around 20 mesh and was nearly liberated at 65 mesh.

COAL BASED DIRECT REDUCTION OF PREOXIDIZED

A chamber furnace is used to carry out the pre-oxidation of chromite ore. The oxidized chromite ore is prepared by heating the initial chromite ore for 2h isothermally at 900 0C in a chamber furnace. A constant flow rate of 40 lpm air is purged inside the furnace to maintain oxidized atmosphere during the preoxidation stage.
