WebThe raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral. Chromite is used as lumpy ores or fine con centrates, which must be generally agglomerated to make them useable charge for the furnace. Fines in the smelting furnace cause unbalanced operation and thus de-crease productivity. WebLatin system • Used when more than one charge • Latin name • Ending is -ous for the smaller charge and -ic for the larger charge • Then ion Example: Copper (I) ion becomes cuprous ion Copper (II) ion becomes cupric ion Now we are ready for the Latin system. Again this is only used when there is more than one charge We will use the latin name … cyn kitchen

Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr2O4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms … See more Chromite minerals are mainly found in mafic-ultramafic igneous intrusions and are also sometimes found in metamorphic rocks. The chromite minerals occur in layered formations that can be hundreds of kilometres long … See more Chromite can be used as a refractory material because it has a high heat stability.
