Washing method of red mud containing goethite |
| abstract |
The present invention provides a method of washing red mud which is suitable for washing red mud of an alumina-containing ore containing a large amount of goethite as an iron component and which can obtain a high solid concentration of the red mud. A method for washing red mud. The red mud is washed with the mass ratio of goethite to hematite in the iron component (goethite/hematite) being more than 60/40 The red mud generated when the alumina-containing ore is heated in an alkaline solution at a temperature of 110-160°C to obtain a sodium aluminate solution is mixed with the diluted solution to obtain an aluminum concentration of 95g / After a suspension of less than L, adding a settling aid containing a polymer containing repeating units derived from (meth)acrylic acid or its salts to the suspension to settle the red mud and separate and wash it It does not substantially contain repeating units derived from vinylhydroxamic acid compounds or salts thereof. |
