9Clean coal technology being practised in coal washeries in India, as pre-combustion clean coal technology, mainly focus on cleaning of coal by removing ash from coal 9Earlier only coking coal was being washed because steel making needs coking coal of ash of 17 to 18%. The raw coal ash in Indian coking coal varies from 25 to 30%. Now-a-days, Min.
• Typical Emissions using raw coal (42%) in a standard Indian coal fired power plant. – Carbon Dioxide – 1.11 kilograms carbon dioxide per kilo watt hour of commercial power • Typical Emissions using washed coal (30%) in a standard Indian coal-fired power plant – Carbon Dioxide – 1.045 kilograms carbon dioxide per kilo watt hour
Bharat Coking Coal Ltd., India have a large deposit of coking coal washery reject with more than 50% ash content. It is a valuable resource as there is a scarcity of coking coal in India. In the present work, the response of Indian coking coal rejects to tribo-electrostatic separation at different relative humidity is studied and its potential ...

The old and non-operational washery will be awarded to the bidder along with the coal linkage corresponding to the highest premium paid for the coal quantity.
energies Article Optimization of Coal Washery Tailings by Flotation Process Changliang Shi 1,2,3, Gan Cheng 1,2,3,* and Shengnan Wang 1 1 College of Chemistry and Chemical Engineering, Henan Polytechnic University, Jiaozuo 454000, China; [email protected] (C.S.); wangsn2015@yeah (S.W.)
Flotation tailings are by-products of coal preparation plants, which do not only occupy cultivated land but also cause pollution. The high ash content and low calorific value of tailings limit their applications. Deashing is the precondition for the reutilization of flotation tailings. However, it is more difficult to remove ash content from flotation tailings …

In Coal India Limited (CIL) has plan to set up 12 new coking coal washeries and one non-coking coal new washery to reduce the quantity of ash and useless component from coal. All these washeries are expected to be operational by FY:2026. Details of new washeries set up or planned in CIL are as under:
Coal washing is a process that is undertaken in a coal washery or coal preparation plant (CPP) where coal is refined or cleaned of impurities. Coal washing involves using water, mechanical techniques and relies on gravity and the difference of density between coal and it's impurities which are usually more densely packed due to …

Froth flotation is a better choice for processing coal washery rejects. In this study, flotation studies are attempted on the coal slurry received from Sudamdih coal washery, Jharkhand, India. A statistical design package (Minitab V17) was used to study the effect of process variables like collector and frother dosages on the responses.
The oxidized coal responded favourably to acid oil, a vegetable oil refinery waste. With acid oil as a collector, the oxidized coal can upgrade to 12% clean ash coal with a 60% yield; the combustible recovered is 80%. The work indicates successful upgradation of fresh and oxidized coal using the froth flotation process.
The recovery of clean coal from washery rejects is of great significance for protecting China's scarce coking coal resources. The main purpose of this work was to design a deep process that can maximize the recovery of clean coal from a coking coal washery rejects with about 50% ash and test the technical feasibility of the process.
