(3) oleum in mass ratio=1 ~ 2: 1 ~ 3 is added in solution 2, react 2 ~ 3 hours under 3 ~ 3.5Mpa condition, then by moisture evaporate to dryness under 50 ~ 60 DEG C of conditions, the solid chemicals of gained is described Sb-Au ore thing collecting agent.
The application of described Sb-Au ore thing collecting agent in flotation Sb-Au ore thing, during flotation, is 6 ~ 6.5 by sulfuric acid adjustment slurry pH; In floatation process, ore ore grinding is dissociated to mineral monomer, add waterglass 200g/t and make inhibitor, add plumbi nitras 50g/t ~ 60g/t again, copper sulphate 60g/t makes activator, add described collecting agent 110g/t ~ 120g/t again, finally add foaming agent 2# oil 80g/t and collecting is carried out to Sb-Au ore thing
The total consumption of described collecting agent is: 110 ~ 120g/t.
During use, the aqueous solution described collecting agent being mixed with in mass ratio 1 ~ 2% adds.
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
Concrete advantage of the present invention is:
1, adopt the collecting agent that is prepared into of the present invention can collecting antimony trisulfide and gold-containing sulfurating mineral, soluble in water, and there is good selective and resistance to low temperature.
2, dosing is few.
