Chrome Ore Extraction Plant

Chromite ore is a mineral aggregate that needs to be processed in order to extract the valuable metals present in the rock. Chromite ore contains the metal chromium as an iron chromium oxide mineral. The chromite ore with a lower grade must be processed to increase its chomite content.

SBM has been speciazlied in mining industry for several decades. We are global supplier of crushing, grinding, and processing equipment. We developed complete series of chromite extraction plant for sale with low price, such as quarry machine, mining equipment, crushing plant, grinding mill, separation machine, drying and washing plant, processing equipment etc. Please chat online with us for detailed information.

Chrome Processing Machine

Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr2O3 and having a chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr2O3 are also used. (Ores high in alumina are preferred for processing into refractory brick.) As finely divided ores, which do not smelt efficiently, come under greater exploitation, a number of processes are employed to agglomerate them for more satisfactory use in furnaces.

Chrome Ore Extraction Operation

Most ores smelted with coke in an electric furnace produce metals that are saturated with carbon. For ferrochromium, the saturation point is approximately 9 percent, but actual carbon content varies with the condition of the ore and the composition of the slag. For example, with a lumpy, refractory ore and a slag containing approximately equal amounts of magnesia, alumina, and silica, a ferrochromium is produced that contains 4 to 6 percent carbon and less than 1.5 percent silicon. This is a result of high temperatures generated by a viscous slag, of a slowly reacting bulky ore, and, possibly, of refining of the molten metal by undissolved ore in the slag.
