Poor quality chromite ore should be processed to improve its chrome content. The processing of chromite ore separates and concentrates the valuable chromite mineral. This involves mechanical processes and separation using gravity, and further chrome refining process.Zenith has been specialized in mining industry for several decades; we provide various types of chromite mining equipment for sale including extraction plant, quarry machine, crushing, grinding, screening plant, processing plant, separation machine, refining plant etc.
Large amount of chromite ore are excavated worldwide. The largest producers were South Africa, India, Kazakhstan, Zimbabwe, Finland, Iran, and Brazil with other countries providing the rest of lower than 10% of the world production. Chromite ore is mined first by surface method. This includes an open pit from which surface material, non-chromite bearing overburden and chromite ore will be excavated. The chromite ore containing rock will be drilled, blasted, removed and delivered onto large trucks to crusher and ore processing equipment. Zenith provides high performance chromite mining equipment for sale.
When chromite deposits are hard to achieve on the surface (depth, cliffs permitting side access), the most effective method to extracted chromite ore is underground approach. The underground mine might be attained from the bottom of the open pit. Blast hole stopping techniques will be employed for underground mining.
Stopping occurs in underground mineral mining when the surrounding rock is strong enough to permit the drilling, blasting, and removing ore without caving. Underground chromite extraction is more expensive to process than surface mining method; however it produces low noise and dust pollution for surroundings.
