Abstract: Methods and ways of recycling of fine coal slurries describing in this article. Coal slurries is industrial waste of coal industry. The advantages and disadvantages of the methods briefly describes. For example, efficiency of enrichment depends on the hardware design and the applied reagents toward flotation; gravity separation is less capital intensive and environmentally safe method; the oil agglomeration is complete processing to reprocess of sludge, however, the method are not received practical application in Russia; briquetting allows to spend fuel having a higher efficiency , lower emissions of sulfur dioxide during combustion and solids from flue gases; the use of coal slurries as a component of water-coal fuel helps to better ignition and effective combusion. The classification of coal slurries describing on the distribution of ash content in them. Comparative analysis apparatus for processing particulate the material describing too. For example, the sediment-machine characterized by high productivity, spiral separator low capital and operating costs, and average-hard hydrocyclones have high precision of separation. It is suggested to make use of both stationary and mobile installations for the enrichment of coal slurries.

Key words: coal slurries methods of processing flotation briquetting separation oil agglomeration
