| titleOfInvention | Oxidized coal slime flotation collector, preparation method and flotation method |
| abstract | The invention discloses a flotation collector for oxidized coal slime and a preparation method thereofA preparation method and a flotation method belong to the technical field of coal slime flotation, and solve the problems of high reagent consumption and flotation cost and low separation efficiency of oxidized coal slime flotation. The collector comprises C 10 ～C 22 Hydrocarbon oil and accelerator including tetrahydrofuran and C 7 ～C 9 An aromatic aldehyde; the composition is C in percentage by mass 10 ～C 22 Hydrocarbon oil 75-80%, tetrahydrofuran 5-12%, C 7 ～C 9 8-20% of aromatic aldehyde. The preparation method comprises mixing 10 ～C 22 Hydrocarbon oil, tetrahydrofuran and C 7 ～C 9 And uniformly mixing the aromatic aldehyde to obtain the oxidized coal slime flotation collector. The flotation method comprises the steps of preparing oxidized coal slime into flotation pulp, adding a collecting agent and a foaming agent into the flotation pulp in sequence, stirring, and then carrying out flotation separation to obtain flotation clean coal and flotation tail coal. The oxidized coal slime flotation collector, the preparation method and the flotation method are used for oxidized coal slime flotation. |
