| titleOfInvention | Scheelite flotation method |
| abstract | The invention provides a scheelite flotation method, wherein a composition of lignocellulose intercalation modified montmorillonite and carboxymethyl cellulose with a mass ratio of 70: 30-85: 15 is selected as an inhibitor, and when the addition amount of the inhibitor is 300-500 g/t, flotation at normal temperature can be realized, and the recovery rate and grade of obtained concentrate are remarkably improved compared with a flotation method using water glass as the inhibitor. The lignocellulose intercalation modified montmorillonite is prepared by slowly adding montmorillonite suspension into lignocellulose suspension and reacting at a constant temperature of 50-70 ℃. The montmorillonite modified by the lignocellulose intercalation has strong adsorbability and dispersibility, has strong inhibiting effect on gangue minerals, has weak adsorption effect on scheelite, and the carboxymethyl cellulose further strengthens the selectivity and inhibiting effect of an inhibitor, so that the flotation separation at normal temperature is realized, and the energy consumption and the cost are reduced. |
