Abstract



In the Southeastern Anatolian Region of Turkey, in Ergani Elazığ and Siirt Şirvan copper ore concentrators, containing the pyrite and the high pyrite content discarded is received as pyrite concentrate from concentrating copper by flotation swept and waste products. Ergani Concentrator produce the pyrite concentrate by product about 350 thousand tons for sulfuric acid production and about 1,700 thousand tons of pyrite waste sent to dispose, Siirt Şirvan copper pyrite is not also evaluated. These pyrite waste products both should be evaluated by the microwave pyrolysis of Turkish Lignites and Şırnak Asphaltite which contains aproximately 8% coal pyrite at seperately disseminated micron and macro sized. The shale and clay content was also separated sellectively in this microwave processing in terms of high carbon contents. In this study, samples are subjected to microwave pyrolysis by roasting of pyrite waste and subsequently pelletized slime mixtures with wood straw samples were subjected to microwave pyrolysis by pyrite at varied power under the temperature 500oC. Active carbon and char matter at the end of microwave pyrolysis were tested. The carbon, ash and moisture volatıle matter improves physical pore types for active carbon at certain degree. The energy need was also minimised at 73% for Şırnak Asphaltite slime by microwave pyrolysis.
