Two basic processes of beneficiation: – Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media. – Wet process: Coal is crushed to smaller size and put in a liquid media of adjustable specific gravity to separate the lighter coal (low ash) from heavier coal (high ash). The rejects from wet process also contain ...

The price paid for the coal is US$ 21 per ton F.O.B. Richards Bay, based on a 6 000 kcal / kg product. The price is adjusted on a linear scale for higher quality coal. The price for 6 100 kcal/kg coal is thus US$ 21,50 and for 6 200 kcal/kg coal, US$ 22. Railage is paid by the colliery on the tonnage of coal railed at a rate of R45/ton.

Abstract. This thesis evaluates the entire coal value chain in order to understand the economic and environmental impacts of the various beneficiation …

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …

Abstract. Coal is a physical mixture of high carbon value coal and rejects. Coal beneficiation is nothing but the separation of these high carbon value coal from rejects (noncarbonaceous material) in a coal body. Although the theoretical knowledge of coal beneficiation is available aplenty in coal preparation books; it is essential that …
