Study of washability of fine ?irnak asphaltite -assesment of advanced washing plant cost

The total amount of asphaltite resource in reserves and production in ??rnak City are over 120 million tons of available asphaltite reserve and about 600 thousand tons per year, respectively. The asphaltite is used in mainly coal boilers for direct heating, and also in industrial furnaces as coal fine. The coal power plants use asphaltite about 400.000 tons per annum in the boiler. The most effective and cost-effective technologies are needed for clean asphaltite production in today's modern technologies. In this investigation, in ??rnak City there are valuable asphaltite reserves on possible cleaning, containing 42% Ash, 6.9% total S (Calorific value 4570 kcal/kg) the standard coal washability studies ??rnak asphaltite were carried out and possible advanced washing plant design was developed and discussed on cost risk data. Regarding this study capital and operational cost risk were calculated, optimum plant units are proposed as larcodem or humprey spiral and column and flotation units. Regarding the proposed project capacities, the capital and operational costs the cost parameters for projected design were determined. Finaly, the production of the qualified asphaltite were managed with 25% ash in clean asphaltite.
