Filtration of coal flotation tailings on large-area filter presses
The environmental conservation problems for coal cleaning plants concern the handling of flotation tailings; they should no longer be discharged into external sludge ponds but rather be converted into a cake suitable for dumping. The most dependable method of conditioning flotation tailings is the dewatering on filter presses; the most popular type, FPAKM-25U, is a vertical filter press of limited throughput capacity. During 1976 to 1979, a filtration section was set up at the Kal'miusskaya Central Washery (P/O Donetskugleobogashchenie) consisting of 4 (subsequently 5) large-area filter presses from Poland (type PF-ROW-1/576, filtration surface area 576 m/sup 2/. The new method of dewatering flotation tailings under pressure in filter presses is less costly than the traditional method of constructing expensive sludge ponds and the necessary pumping facilities and pipework. The saving at the Kal'miusskaya Central Washery is estimated at approx. 250,000 roubles/year.
