| titleOfInvention | Application of the hydroxypropyl starch ether in Scheelite Flotation |
| abstract | The present invention relates to a kind of application of technique of preparing more particularly to hydroxypropyl starch ether in Scheelite Flotation.The present invention can inhibit Scheelite Flotation using depressing agent hydroxypropyl starch ether, significantly improve the gangue minerals such as fluorite, calcite aluminium silicate mineral and scheelite mineral floatability difference, it realizes that gangue mineral is separated with the reverse flotation of scheelite, solves the problems, such as that the gangue minerals such as scheelite and calcite, fluorite, aluminium silicate mineral separate hardly possible.The depressing agent that the present invention uses is conducive to the raising of Scheelite Concentrate grade and the rate of recovery, shortens flotation flowsheet, reduces production cost, and it is horizontal to improve comprehensive utilization of resources. |
