The invention relates to an ore dressing technology, in particular to application of cationic etherified starch in scheelite flotation. According to the application, a used depressing agent cationic etherified starch can inhibit scheelite flotation, the floatable difference of gangue minerals such as fluorite, calcite and aluminosilicate and scheelite is remarkably improved, reverse flotation separation of the gangue minerals and the scheelite is achieved, and the problem of difficult separation of the scheelite and the gangue minerals such as fluorite, calcite and aluminosilicate is solved. The used depressing agent is conductive to the improvement of scheelite concentrate grade and recovery rate, a flotation process is shortened, the production cost is reduced, and the comprehensive resource utilization level is improved.
