The ore is mined either up-dip or down-dip in rooms approximately 20m wide, with the roof supported by ore pillars. Scrapers haul chromite to ore passes that load trains on the haulage level. The trains load a conveyor in the hoisting adit.
Chromite is the most important chromium ore mineral. It forms a complete solid solution series with many other members of the group, eg. in the Chromite-Hercynite Series, Chromite-Spinel Series, Chromite-Magnetite Series and the Chromite-Magnesiochromite Series.It is the iron analogue of Zincochromite, Cochromite, Manganochromite and Magnesiochromite and the Cr analogue of .

Alibaba offers 1,343 chrome ore price products. About 10% of these are Chrome Ore, 5% are Refractory, and 6% are Other Metals & Metal Products. A wide variety of chrome ore price options are available to you, such as concentrate or not.
Ore supply to the ferrochrome industry Geologically the world's chromite ore resources are found in either podiform- or stratiform-type deposits. Podiform-type chromite deposits occur in irregular shapes like pods or lenses. Their distribution within a mineralized zone is erratic and unpredictable, making exploration and exploitation costly.

Chromite ore is usually a combination of spinels with associated minerals such as calcite, magnetite, talc, serpentines and uvarovite. Chromites crystals exhibit an octahedral structure similar to magnetite. The Cr 3+ ions are in the octahedral position with oxygen. The chromium rich phase is antiferromagnetic.

Chromite and ilmenite have very similar properties. Careful observations of hardness, streak, and specific gravity are required to distinguish these minerals in hand specimens. Uses of Chromite. Chromite is the mineral ore of the metal Chromium, and the chromium must often be extracted from the ore and purified before it is used.

important ore deposits are located in the mantle section (hartzbugite-dunite sequences), but also in dunite section are encountered significant concentrations of the banding chromite. There are three distinct types of ore: concordant, sub-concordant and discordant, where the most important is the sub-concordant type. Chromite bodies display a great
