The world's largest coal-consuming countries in 2019 were China and India, with China using a total of 81.7 exajoules and India, 18.6 exajoules. Based on these figures, China accounted for approximately 51.7% of the world's total coal consumption in 2019, and India at 11.8% .
Coal mined from the Talcher region of Odisha, India is known to be high-ash, surface-oxidized, and noncoking in nature. It is quite challenging to beneficiate such low-grade coal by physical or physicochemical processes due to its oxidized nature and the presence of complex ash forming mineral matter in its matrix. Chemical beneficiation is one of the alternative process to such …

Coal Beneficiation Cost It has been used as an excuse as a deterrent to beneficiation. It has been reported that the washing cost may be as high as Rs160 per ton ($3.56/ton). It has also been reported that a leading coking coal producer in the private sector with more intensive washing (-15mm coal: DMC + Flotation +
A process for removing mineral matter from coal is disclosed. The process involves creating ultrafine coal by pulverizing the coal feed material and mixing it with an aqueous amine solution.The coal / amine solution is fed into a flotation cell and gaseous carbon dioxide is charged into the cell.The carbon dioxide reacts with the amine solution to form bubbles which …

Coal Beneficiation is a process where coal is subjected to a medium of defined specific gravity. Heavier material sinks (rejects) and lighter coal floats (clean coal). This specific gravity is defined by the 'washability' characteristics of the coal seam. It varies for different seams in the same area and for different geographical areas.
6 AUSTRALIA TECHNOLOGY IN VOGUE Raw coal crushed to 50/60 mm. Coarse coal washing Mainly by DMC (Dia:1000 mm or more) Drums or Baths in some plants. Jigs at few plants. Fine coal washing Spiral + Jameson or Microcel technology. Limited use of froth flotation for metallurgical coal. Dewatering Coarse & medium size- Vibrating or scroll type basket
I shall try to highlight the growth of beneficiation in coal and leading to the need for adoption of flotation circuits. Beginning in early 50's when the upper horizon with low ash and low near gravity materials were mined, all either jigging or heavy media baths for beneficiation was found effective. The fines were taken out before the feed into the cleaning circuit.

The flotation method reduced — 50% ash along with most of sulfate sulfur (>90%) and 66.9% of the pyritic sulfur from the coal sample. Column flotation has an advantage over conventional flotation as it can provide higher concentrate grade and recovery, lower maintenance costs, and improved process control [Groppo and Parekh, 1990].
In coal flotation, only collectors and frothers are generally used as chemical reagents. The collector enhances the hydrophobic property of coal. Kerosene or No 2 fuel oil are usually used as collectors, while aliphatic alcohols such as MIBC (methyl isobutyl carbinol) and glycols are normally used as frothers.
