Description
Technical field
The present invention relates to technical field of beneficiation, specifically a kind of zinc sulfide ore method for floating.
Background technique
Existing lead-zinc sulfide ore flotation generally uses xanthate as collecting agent, and according to statistics, 67 Ge Xuan factory of the U.S. is total within 1980
Consume 4500t medicament.Wherein xanthate accounts for 65%.Thus xanthate is the main collecting agent of lead-zinc sulfide ore.But it uses yellow
When medicine carries out mineral floating, usually to make pH>10, so that its flotation effect reaches best.At this moment pH values of pulp is higher, and discharge can make
At environmental pollution.Meanwhile although xanthate collecting ability is stronger, selectivity is poor, and some pyrite can usually be made to float.
Summary of the invention
The present invention in view of the above shortcomings of the prior art, provides a kind of zinc sulfide ore method for floating, can be improved vulcanized lead
The rate of recovery of zinc ore floating zinc reduces dosing, saves beneficiation cost.
The present invention realizes that technical solution used by above-mentioned purpose is：A kind of zinc sulfide ore method for floating, by butyl ammonium aerofloat
It is configured to confection by a certain percentage as collecting agent, including such as with O- alkyl-N- alkoxy carbonyl thiocarbamate
Lower step：
(1) flotation agitator is added in broken raw ore and carries out roughing, every 1000 kilograms of additions 40-50g in rougher process
The confection, obtain rougher concentration and one tailing of roughing,
(2) one tailing of roughing is further scanned out by the confection that 10-16g/t is added in every 1000 kilograms of ore pulps
Zinc ingredient in tailing obtains two tailing of roughing,
(3) two tailing of roughing is further scanned out by the confection that 10-16g/t is added in every 1000 kilograms of ore pulps
Zinc ingredient in tailing.
The confection refers to black powder and thiourethane by mass percentage concentration 15-20：The ratio of 70-80 prepare and
At.
Compared with prior art, the beneficial effects of the invention are as follows：
Butyl ammonium aerofloat and O- alkyl-N- alkoxy carbonyl thiocarbamate will be configured to mixing medicine with certain proportion
Agent replaces xanthate as collecting agent, improves the rate of recovery of Pb-Zn deposits in lead-zinc sulfide ore flotation, reduces collector dosage,
The confection dosage of 1000 kilograms of raw ores is that 60-82g/t reduces 90-118g/t, make than using xanthate 150-200g/t
Beneficiation cost reduces, and reduces environmental pollution.
Specific embodiment
Technical solution of the present invention is described further by the following examples.
Embodiment 1
1000g/t lime is added to inhibit sulfide mineral 2 minutes, copper sulphate 300g/t is added and reacts 2 minutes, is added described mixed
It closes medicament 40g/t and carries out roughing, the tailing of acquisition adds the confection 10g/t, sizes mixing and carry out flotation after five minutes, institute
Tailing adds confection described in 10g/t and is scanned, by roughing twice, primary cleaning, once purging selection, flotation is final
Zinc ore content in tailing is 0.42%.With use true tailings Zn content 0.78% obtained by xanthate to compare, flotation effect is more preferable.
Embodiment 2
1000g/t lime is added to inhibit sulfide mineral 2 minutes, copper sulphate 300g/t is added and reacts 2 minutes, is added described mixed
It closing medicament 45g/t and carries out roughing, the tailing of acquisition adds the confection 13g/t, it sizes mixing and carries out flotation after five minutes, institute
Tailing adds confection described in 13g/t and is scanned, by roughing twice, primary cleaning, once purging selection, flotation is final
Zinc ore content in tailing is 0.33%.With use true tailings Zn content 0.55% obtained by xanthate to compare, flotation effect is more preferable.
Embodiment 3
1000g/t lime is added to inhibit sulfide mineral 2 minutes, copper sulphate 300g/t is added and reacts 2 minutes, is added described mixed
It closes medicament 50g/t and carries out roughing, the tailing of acquisition adds the confection 16g/t, sizes mixing and carry out flotation after five minutes, institute
Tailing adds confection described in 16g/t and is scanned, by roughing twice, primary cleaning, once purging selection, flotation is final
Zinc ore content in tailing is 0.24%.With use true tailings Zn content 0.39% obtained by xanthate to compare, flotation effect is more preferable.
