Fig. 3 is the flow chart of the embodiment of the invention 3.
The specific embodiment
Embodiment 1
Adopt high-efficiency cleaning of the present invention to select the sulphur method, select sulphur to carry out small-scale test and commerical test, obtained sorting index preferably the copper tail in certain mine.Element sulphur in this ore mainly exists with chalcopyrite, magnetic iron ore and three kinds of forms of pyrite.Chalcopyrite and gangue are in close relations, based in, the extremely inhomogeneous embedding cloth of carse, medium and small particulate of fine-grained disseminated grain.The pyrite disseminated grain size is relatively thick.Magnetic iron ore and magnetic iron ore disseminated grain size are thinner.In a word, its ore belongs to the difficulty of fine-grained disseminated grain and selects polymetallic ore, the raw ore of cupric 1.07%, sulphur 18.13%, iron 32.61% wherein, through talcum flotation, the diffeential floatation of copper part, the bulk flotation of copper sulphur, mix roughly select concentrate and copper concentrate I tailing regrind to-0.045mm account for 90%, copper sulphur content is from flotation, separates mine tailing as the ore deposit of giving of selecting sulphur.Have only the on-the-spot sample of 15-25% to be concentrated to 30% to the sulphur floatation concentration, add the listed reagent combination of table 1, through the one thick one single-minded small-sized closed-circuit test (flow chart is seen Fig. 1) of sweeping, having obtained the sulfur-bearing grade is more than 35%, and the rate of recovery surpasses 87% sulphur concentrate.
Embodiment 2
Certain copper mine raw ore sulfur-bearing is low, and sulphur copper ratio is 2: 1, and callable effective sulphur only is about 1%.Magnetic iron ore (Fe
5S
6) be one of main sulfide mineral in the ore.Mainly be irregular embedding be distributed in the gangue mineral or magnetic iron ore and gangue mineral gap in, glued explanation magnetic iron ore, the relationship of the two is close, secondly stone ore thing crack or the clearance filled net veiny that is along the pulse.The embedding cloth relation of magnetic iron ore and chalcopyrite is also very close, and Chang Kejian chalcopyrite filling in the magnetic iron ore gap in magnetic iron ore, has the fine inclusion enclave of chalcopyrite.The granularity embedding cloth of magnetic iron ore is inhomogeneous, and is mainly between 20～295 μ m, a little than the chalcopyrite coarse size.Because magnetic iron ore mostly is the embedding Bu Tezheng of glued explanation magnetic iron ore, particulate magnetic iron ore and magnetic iron ore are not easy monomer separation, and adding magnetic iron ore and magnetic iron ore all is the ferrimagnetism mineral, has ferromagnetism, and the two interferes with each other in the process of sorting.In addition, magnetic iron ore molecule and crystal structure determine poor, the surperficial characteristic such as easily oxidation and the crisp easy argillization of property etc. of its floatability.Adopt the method for the invention, to mixed copper sulphur content from the copper mine tailing carried out one roughing, primary cleaning, scan for twice small-sized closed circuitly select sulfur test (flow process is seen Fig. 2).-0.074mm accounted for 85% ore pulp and be concentrated into 30%, after adding 8000 gram/ton oxalic acid, 300 gram/ton ammonium hydrogen sulfates, the activation of 1500 gram/ton ferrous sulfate are sized mixing, butyl xanthate and 50 gram/ton butyl ammonium aerofloats with 300 gram/tons carry out collecting, sweep small-sized closed-circuit test through a thick essence two and can obtain grade and the rate of recovery and be respectively 36.12% and 85.83% sulphur concentrate.
Embodiment 3
Ore deposit, Xinjiang iron ore all iron content is 50.76%, and sulfur content is 10.07%, and the iron in ore mineral are based on magnetic iron ore, and sulphur mainly exists with magnetic iron ore and pyritous form.Raw ore is milled to-0.074mm accounts for 85%, carried out one thick two smart low intensity magnetic separation test, obtained the iron grade and be 64.07%, iron recovery is 86.40% iron ore concentrate.But because the stronger magnetic iron ore of magnetic also is enriched in the iron ore concentrate in the magnetic separation process, cause the sulfur content of iron ore concentrate to rise to 10.47%, can't utilize.For this reason, adopt the method for the invention, after interpolation 2000 gram/ton ammonium carbonates, 1000 gram/ton carbonic hydroammonium and the activation of 800 gram/ton ferrous sulfate, this iron ore concentrate is carried out the one thick two single-minded reverse flotation desulfurizing of sweeping with 240 gram/ton butyl xanthates.Make in the iron ore concentrate sulfur content reduce to 0.25%, the iron grade also is increased to more than 68%, has obtained the grade and the rate of recovery and has been respectively 36.52% and 84.13% sulphur concentrate.
