Description
Technical field
The present invention relates to a kind of beneficiation method of high tin-polymetallic sulphide ore, belong to Mineral Processing Engineering technical field.
Background technology
China's stanniferous sulfide ore tin mineral disseminated grain size thickness inequality, tin mineral character is very crisp very easily to be formed sludge and cannot reclaim in grinding process. This just requires grind grading process to adopt the method that selective corase grind, high-effective classifying, coarse grain are regrinded to be avoided as much as possible cassiterite to cross pulverizing, simultaneously to primary tin ore mud and cannot avoid produce sludge adopt method for floating can effectively reclaim.
The at present ore dressing of stannum-contained multi-metal sulphide ore floating-heavily the technique of associating, an ore grinding is as main, grind grading adopts traditional grinding grading technique, adopt steel ball mill ore grinding, obtain the product that 0.074mm accounts for 70% above granularity below and be beneficial to flotation and recovery of copper, lead, zinc sulfides, flotation tailing adopts reselecting method to reclaim tin mineral. This technique has that flow process is simple, flotation recovery rate is high, the advantage of easy operating, but also exists following problem: (1) ore milling product size distribution inequality, and coarse fraction and ultra-fine grade sludge are many, and there is the serious problem of pulverizing of crossing in the mineral that density is large; (2) the tin mineral rate of recovery is low, and Fine cassiterite reclaims without effective ways; (3) be only applicable to the sulfide ore that copper Pb, Zn content is high, tin content is low.
Summary of the invention
For problem and the deficiency of above-mentioned prior art existence, the invention provides a kind of beneficiation method of high tin-polymetallic sulphide ore. This beneficiation method is that 0.074mm accounts for more than 70% below by the high tin-polymetallic sulphide ore grinding particle size of routine, becoming grinding particle size is that 0.074mm accounts for 60% selective milling below, therefore can reclaim to greatest extent cassiterite and sulfide wherein, the present invention is achieved through the following technical solutions.
A beneficiation method for high tin-polymetallic sulphide ore, its concrete steps are as follows:
Step 1: first by the following granularity of high tin-polymetallic sulphide ore crushing raw ore to 15 ~ 20mm, then the high tin-polymetallic sulphide ore after fragmentation is entered to rod mill open-circuit grinding, rod milling ore discharge obtains overflow and sand setting through hydroclone classification, overflow enters into copper-lead bulk flotation, sand setting is through high frequency vibrating fine screen classification again, oversize enters overflow shaped steel forging ball mill and regrinds, undersize enters copper-lead bulk flotation, steel forging ball mill ore discharging product and the merging of rod mill ore discharge are got back to hydrocyclone and are formed closed circuit classification, wherein the undersize of hydrocyclone overflow and high frequency vibrating fine screen classification merges that to obtain granularity be that 0.074mm accounts for below 60% ore milling product and enters flotation operation,
Step 2: the ore milling product that step 1 obtains enters copper-lead bulk flotation, flotation chats enters small grinder to be continued to select by copper-lead bulk flotation after regrinding again, and the Copper-lead mixed concentrate of output adopts two sections of shaking tables to separate and obtains lead concentrate, copper concentrate and copper-lead flotation tailing; The copper-lead flotation tailing of output carries out zinc flotation output zinc concentrate, zinc chats and zinc mine tailing, roughly selects the zinc chats obtaining and adopts vertical mixing mill regrinding and reconcentration output zinc concentrate;
Step 3: the zinc mine tailing that step 2 obtains is selected magnetic iron ore after magnetic separation, then after, desulfurization flotation concentrated through concentrator, obtain sulphur arsenic bulk concentrate and sulfur-bearing 4wt.% desulfurization mine tailing successively, sulphur arsenic bulk concentrate obtains containing arsenic lower than the low pozzuolite concentrate of 0.5wt.% and high arsenic mine tailing after sulphur arsenic separating flotation, desulfurization mine tailing adopts three sections of shaking tables to select the thicker high-grade tin concentrate of granularity, and the chats that shaking table is selected is selected high-grade tin concentrate through after backwashing shaking table after regrinding; Shaking table mine tailing out adopts spiral classifier and the classification of large tilting plate board concentrating box to concentrate, and coarse fraction is for abandoning mine tailing; Granularity is that the middle grade of 10 ~ 40 μ m adopts and outstandingly shakes that conical surface Disk Concentrator is roughly selected, table concentration output tin concentrate; Sand setting and overflow that fine fraction is 25% through the concentrated classification output concentration of small-bore waterpower cyclone, sand setting adopts the rich chats of tin flotation (adopting the collectors for cassiterite flotation of BY-9 and P86) output tin, and overflow adopts the recovery of large area blanket sluice, the rich chats of the selected output tin of belt shaking table.
Described high tin-polymetallic sulphide ore is stanniferous higher, and taking tin ash as main, grade reaches 0.5 ~ 1wt.%.
High frequency vibrating fine screen screen size in described step 1 is 0.2 ~ 0.3mm.
When Copper-lead mixed concentrate in described step 2 adopts shaking table separating technology, cupric 11 ~ 15wt.% in Copper-lead mixed concentrate, plumbous grade 5 ~ 15wt.%.
Sulphur arsenic bulk concentrate ore deposit in described step 3 adopts medicament to suppress arsenic mineral through sulphur arsenic separating flotation, as the medicaments such as sodium humate, hydrogen peroxide, waterglass suppress arsenic mineral.
Shaking table mine tailing out sorting of classified, the concentrated distinct methods that carries out narrow grade again in described step 3, the grind grading method adopting can overcome crisp easy excessively pulverizing of tin ore physical property and produce too much sludge, and the sludge that is difficult to avoid is adopted to the method for efficient cassiterite flotation and blanket sluice, realize the wholegrain level high efficiente callback of tin mineral.
It is that 0.074mm accounts for below 60% and is for the principle that sorts material that the present invention selects high tin-polymetallic sulphide ore granularity: make to sort the material only powder that fully dissociates through two sections of classifications of two stage grinding, comprehensively reclaim the various metals, particularly tin such as plumbous zinc-copper tin with flotation gravity treatment integrated processes and obtain good effect.
The invention has the beneficial effects as follows: (1) high tin-polymetallic sulphide ore was avoided as far as possible pulverizing in grinding process, be difficult to avoid the sludge producing to adopt method for floating to reclaim to primary slime and part simultaneously, can reclaim to greatest extent tin mineral, all recovery that have valency metal sulphide mineral are simultaneously taken into account, valuable mineral in ore is reclaimed to greatest extent, improve mineral resources comprehensive reutilization rate; (2) the tin concentrate of output becomes high-grade tin concentrate and low-grade rich chats from original tin concentrate, and the tin rate of recovery has improved more than 20%, and copper recovery has improved more than 2%, and plumbous zinc recovery remains on previous level substantially, and sulfur recovery rate reaches 90%.
