Abstract
The present study has been undertaken to assess the relationship between raw coal and effluent quality of Zarand coal washery plant, Kerman province in southeast Iran. Coal samples, raw coal feed, washed fine clean coal and middling were collected. In washing process, raw water (intake to washery) and effluent samples generated in the washeries, namely, fine coal jig under water and tailing pond water were collected during August-September 2009. In coal samples, trace elements were determined in various fractions of Zarand coal washery. Parameters such as pH, temperature, colour, odour, TSS, oil and grease, COD, and trace and heavy metals were measured in washery processing. TSS, COD and oil and grease were very high in water samples. Trace elements like Cu, Ni, Zn, Pb, Cr, Mn and As were found to be present in the process water indicating that these elements are not released by coal during washing.
