Abstract: 

Mine and mineral processing plant’s Tailings, are among the most important sources of acidic drainage in many part of the world. So attempts have been made to become acquaintance with the probable source of acidic drainage and to control and neutralize these effluents in coal mine. Since East Alborz coal region is one of the most important area which produce coal concentrates in steel industry, this plant produce a large amount of tailing which have the capacity of generating acidic drainage. Regarding to the large amount of tailing around the East Alborz coal washing plant, studies have been made to predict the potential of acidic effluents generation. In primarily laboratory studies which was done with “Modified Acid Base Accounting” test, we found that the old tailing of the jig have the potential of producing acidic drainage but the other tailing have unclear status. So, for understanding the status of all tailing, it is suggested that some kinetic tests will be done on this tailing.
