Tween-20 and phaco time is 40 ~ 50min when PEG-400.
The present invention also provides a kind of application of collecting agent in lead antimony zinc vulcanizing mine bulk flotation, and regime of agent is thick
25 ~ 35 g/t of copper sulphate, 15 ~ 25 g/t of the collecting agent when selecting, 8 ~ 12 g/t of collecting agent when scanning, the ore pulp of flotation is not
PH regulator need to be added, using nature pH, foaming agent is not added.
Compared with the existing technology, the hybrid collector for the zinc vulcanizing mine flotation of lead antimony of the invention has the advantage that
1) the hybrid collector stability is good, can be stabilized 60min at room temperature with emulsion form, add emulsus after water
Drop d50Being basically unchanged can be stablized within the flotation of ore pulp time and play a role；
2) hybrid collector is strong in the dispersibility of ore pulp, sufficiently with mineral effect, it is obvious to improve floatation indicators；
3) the hybrid collector foaming characteristic is good, and foam is tiny, uniform, can be reduced foaming agent use, or can replace
Infusion；
4) hybrid collector (being calculated with actual tert-dodecyl mercaptan with emulsified kerosene quality summation) and foaming agent are used
Amount is reduced, and reduces reagent cost.
Hybrid collector of the invention has preferable collecting to act in sulfide, and it is floating to can be applied to lead antimony zinc vulcanizing mine
Choosing.It has good foaming characteristic, can add less or foaming agent is not added, can reduce the dosage of activator copper sulphate.It compares simultaneously
Traditional MA, exclusive use tert-dodecyl mercaptan and emulsified kerosene, can be improved the grade and the rate of recovery of sulfide, reduces medicament
Type and dosage.
