USAGE OF WASHED COAL IN INDIA: ISSUES AND CHALLENGES

intensive washing (-15mm coal: DMC + Flotation + Dewatering) and is known to wash coal at Rs100-120/ton ($2.22 - $2.67/ton). Moreover, there is every reason to believe, that given enough market opportunity and perhaps the existence of a price regulatory body, this cost will comedown to well below Rs80/ton ($1.78/ton). Electricity Cost A simplistic notion of higher electricity cost coming from ...

Coal dense medium separation dynamic and steady-state ...

fine coal dense medium cyclone (DMC) circuit. In this paper, the previous model is adapted to a coarse coal DMC circuit and validated over a wider range of operating conditions using real plant data. The model is further validated by reducing it to steady-state to form a partition curve. This curve is then compared to one derived from actual production data. The derived model is able to ...

Compared with cationic P(AM‐DMC) (CPADM), Commercial cationic polypropanamide (CCPAM‐1 and CCPAM‐2), TPADM had better flocculation effect on coal washing wastewater. Under the optimum flocculation conditions (dosage = 16 mg/L, pH = 7.5), suspended solid (SS) concentration and turbidity of coal washing wastewater treated by TPADM reached 14.3 mg/L and 8.7 NTU, respectively. The floc ...

Coal Cleaning - an overview | ScienceDirect Topics

Medium-to-coal Ratio. To run a DMC smoothly, it is necessary to maintain the volume of the medium and the solids feed rate. The medium to coal values should typically range from 3.5 to 4. Rarely, a DMC can perform well with ratios below 3. When the feed rate to the process is increased, the medium-to-coal ratio generally decreases. The effect of the lower medium-to-coal ratio needs to be ...
