Detailed description of the invention
For Yunnan complex multi-metal micro fine particle sulphide ore, have employed present invention process respectively and carry out test and gravity treatment contrasts.The particle that in these mineral, cassiterite particle diameter is less than 0.075mm accounts for 55.32%; The particle being less than 0.038mm accounts for 21.93%.Raw ore Sn content is 0.51%, Cu 0.32%, Zn, 0.78%, Fe 10.49%, and main gangue mineral is quartz and carbonate mineral.
Magnetic separation of the present invention High-gradient Magnetic field intensity used can be 2000-3000Gs.
Embodiment float test of the present invention (as shown in Figure 1):
(1) according to the embedding cloth characteristic of ore, this ore comminution to-200 orders are accounted for 95%, makes cassiterite monomer dissociation substantially, add sodium carbonate during comminution as ore pulp dispersant and pH adjusting agent;
(2) by ore pulp in magnetic separation strength be 2100Gs condition under carry out magnetic separation, to remove magnetic mineral wherein, obtain iron rough concentrate and mine tailing;
(3) magnetic tailing carries out floatation desulphurization (one roughing is scanned for twice), and concrete steps are: add xanthate collectors 60g/t, foaming agent 20g/t, carry out mixing roughly select sulphide ore, obtains sulfur-bearing rougher concentration (i.e. mix sulphur concentrate); Rougher tailings adds activator copper sulphate 80g/t, xanthate collectors 40g/t, foaming agent 2# oil 30g/t carries out mixing and scans (i.e. the flotation of zinc), obtain sulfur-bearing scavenger concentrate (i.e. zinc rough concentrate), mix sulphur concentrate and crude zinc concentrate are selectedly separated copper, the zinc concentrate that can reach sale standard through follow-up again; Scan mine tailing (i.e. zinc flotation tailing) and add sulfuric acid, by pH adjustment about 8, add 50g/t xanthate collectors and foaming agent 2# oil 20g/t carry out sulphur removal operation, gained sulfur-bearing mine tailing (desulfurization gained concentrate) directly abandons;
In sulfide flotation test, sulphide ore is categorized as and can utilizes sulphide ore and sulphide ore can not be utilized to carry out stepped-flotation separation, first select available sulphur rough concentrate and zinc rough concentrate, selectedly obtain copper concentrate and zinc concentrate through follow-up, this floatation process adds xanthate collectors, activator copper sulphate, foaming agent 2# oil; For not available sulphide ore, should remove in floatation process as far as possible, about first utilizing sulphur acid for adjusting pH to 8.0, then add xanthate collectors, 2# oil carries out except sulfur test.
(4) desulfurization mine tailing enters tin-lead soldering: in floatation process, first add pH adjusting agent sulfuric acid, pH is adjusted to about 7.5, then adds activator plumbi nitras, consumption is 150g/t, the inhibitor added is sodium carboxymethylcellulose and waterglass, consumption is 250g/t, and the collecting agent added is hydroximic acid collecting agent, and consumption is 2000g/t, add No. 2 oil as foaming agent, consumption is 30g/t.Wherein the mixing time of collecting agent is 20 minutes, and slurry temperature maintains about 25 DEG C.Through one roughing, once purging selection and four times selected (scavenger concentrate and cleaner tailings merge into medium tin ore), the selected mine tailing of cassiterite is more or less the same with tin grade in the concentrate scanned, therefore considers to be merged, and together return cassiterite and roughly select, acquired results is as table 1:
Table 1
Carry out closed-circuit test according to above-mentioned flow process (the selected chats of tin and scavenger concentrate return tin and roughly select, and selected two, three, the four gained chats merging of tin return tin selected one), acquired results is as table 2:
Table 2
Comparative example gravity treatment test (as shown in Figure 2):
Adopt shaking table to carry out gravity treatment test to this ore in this test, result is as table 3:
Table 3
Gravity treatment result of the test shows, for the cassiterite of fine grain teeth cloth, when mog is thicker, cassiterite liberation degree of minerals is low, causes with gangue mineral difference in specific gravity not obvious thus, and gravity treatment can not be effective separation; When its mog is thinner, known by Stokes' law, its rate of settling and gangue particle rate of settling gap less, gravity treatment can not be effective separation.Therefore for the type ore, gravity treatment is not effective separation method.
The above two kinds of test methods of contrast are known: in gravity treatment test, when mog is thicker, obtain that grade is 0.77%, the rate of recovery is the Tin concentrate of 65.81%, when mog is thinner, obtain that grade is 1.01%, the rate of recovery is the Tin concentrate of 45.49%, show that gravity separation method can not make the type ore be effectively separated.In float test: in conjunction with technique that this explanation is introduced and regime of agent, open-circuit test can obtain that grade is 46.09%, the rate of recovery is the Tin concentrate of 49.32%, closed-circuit test can obtain that grade is 40.21%, the rate of recovery is the Tin concentrate of 63.95%, obtains more effective separation.
