BRIQUETTING OF FINE SIZE ASPHALTITE WITHOUT BINDER

Mineral Processing and Extractive Metallurgy Review, 2005
ABSTRACT In this study, the effects of particle size, moisture, briquetting pressure, and preheating temperature were investigated on briquetting without binder of Sirnak Asphaltite, having a particle size of—20 mm, 46.22% ash, 5.83% total sulphur content, and 4900 kcal/kg calorific value.

Pyrolysis Kinetics of Asphaltite by Thermal Analysis

Petroleum Science and Technology, 2006
Abstract Pyrolysis properties and kinetic analysis of asphaltite were investigated by means of thermogravimetry (TG) and derivative thermogravimetry (DTG). Thermal experiments were carried out from ambient temperatures to 1000°C in nitrogen atmosphere at different heating rates.

Support design of underground openings in an asphaltite mine

Tunnelling and Underground Space Technology, 2013
Abstract A detailed study to design support systems for underground openings was carried out in this paper. Asphaltite, an energy source for thermal power plants, will be produced from the Uckardesler Asphaltite Vein in southwestern Turkey. This mine will be the first application of underground asphaltite production in the world.

Molybdenum speciation in asphaltite bottom ash (Seguruk, SE Anatolia, Turkey)

Fuel, 2012
Asphaltites derive from petroleum origin. The combustion of asphaltites produces fly and bottom ashes that are characterized by a high content of valuable elements such as vanadium, nickel, molybdenum, uranium, thorium, sulfur and unburnt carbon.
