Abstract

Suspended fine particulate matters generated from different mining activities such as washing and crushing of coal affect large volume of natural waster. The present paper highlights a simple method to improve the settlement rate of dispersed coal fine particles by incorporating them into a coarser particulate matrix. The process mentioned herein consists of three steps viz. activation of coal fine in aqueous medium, tether of activated particles to the anchor particles and pass them into straight flow stream. The activation of coal fines suspended in the effluent water may be an amine group of polymer which can link to a particle surface of metal oxide to complete the interaction for sedimentation of coal fines. The coagulated cal fine is further separated by gravitation an filtration process.
