Chromite Beneficiation Process

The Problem with Chromite ProcessingThe Chromite Extraction FlowsheetChromite Process SummaryExperience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus 16 mesh, it is obvious that the plus 16 mesh particles should be removed after stage crushing and grinding to prevent further reduction of the chrome and consequent...

Chromium processing | Britannica

Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated

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...

Ferrochrome

Ferrochrome, or Ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy between chromium and iron, generally containing 50% to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.
