| 摘要 |
The invention concerns to processing of aqueous slime of metallurgy production. A method comprises the dispersion of slime, containing iron ore, in aqueous solution of lime, soda and salts of calcium of magnesium, agglomeration of obtained suspension in lights, supply of lighted material in sedimentation reservoirs, classification of supplied material with separation of proof thin suspension and deposited granular product, subsequent operations of concentration and dehydration with obtaining of thin and granular fraction of dried iron ore. Components of slam are taken in the following rate, w/w: lime – 0.1-4.0, soda – 0.1-8.0, salts of calcium or magnesium – 0.1-4.0, iron ore – other. Technical result: increase of efficiency of material separation on fractions. |
