Method for improving transparency of drain in production of coal |
| abstract |
FIELD: coal waste processing. n SUBSTANCE: processed coal waste and a method for separating water from coal waste are proposed. Processed coal waste contains from 20% by weight to 80% mole percent non-expanding clay and an anionic copolymer of acrylate-acrylamide having from 36 to 44 mole percent (meth)acrylate, 56 to 64 mole percent (meth)acrylamide and reduced specific viscosity from 22 to 28 dl/g. n EFFECT: invention provides improved drain transparency in coal production. n 17 cl, 5 dwg, 1 tbl, 3 ex |
