Salt Flotation of Şirnak Asphaltite

Energy Sources, Part A: Recovery, Utilization and Environmental Effects, 2011
Abstract The aim of this study was to investigate the possibility of cleaning Sirnak asphaltite by salt flotation. For this purpose, experimental studies were conducted on a Sirnak asphaltite sample containing high ash and sulfur content. The effects of salt amount, pH, frother amount, and impeller speed on the flotation were investigated separately in

Selective oil agglomeration in Sırnak asphaltite beneficiation

Fuel, 2004
Abstract In this study, the possibility of cleaning Sirnak asphaltite by the agglomeration method was investigated. Experimental studies were conducted on the asphaltite sample with ash, sulphur, volatile matter and fixed carbon contents of 44.8, 6.0, 38.0, and 17.2 wt%, respectively. For this purpose, laboratory tests were carried out to investigate
