Chrome mining process. Chrome ore mining process contains consists of primary crushing, screening, lumpy and chip dense media separation (“DMS”), milling, spirals fine treatment, coarse discard and tailings thickening.
The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.
Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process

In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. (Chrome) Surface mining (open pit mining) and underground mining (shaft mining). and high pressure below the surface make shaft mining very complex, dangerous and expensive. A diagram illustrating open cast
organized industries—mining has an ancient and venerable history (Gregory, 1980). To understand modern mining practices,it is useful to trace the evolution of mining technology,which(as pointed out earlier in this chapter) has paralleled human evolution and the advance of civilization.
mine produces 3 grades of chrome ore, namely lumps, chips, and concentrates. The lumps and chips of chrome ores are used as raw material and are directly fed in submerged arc furnace, while the concentrates of chrome ore must undergo agglomerating treatment, such as sintering or pelletizing.

Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. The Kimberley Big Hole is an example of open-pit mining. In underground mining
