Abstract: 

Medium consumption is a significant component of the cost of operating a dense medium plant. This study aimed to identify and quantify many of the factors contributing to overall consumption. Particular attention was given to the effect of operating density on medium loss. Density should therefore be minimized, commensurate with process requirements. There is also unequivocal evidence that consumption increases significantly with plant downtime, probably due to housekeeping wastage and overloading of regeneration circuits during return of dumped medium to circuit. Medium consumption in zarand washing coal plant is reported 5kg/t. investigation is perform of tree dansity (1/3, 1/4, 1/45 kg/l). cause medium loss related screen washing configuration, magnetic separation and screen drainage efficiency.
