Abstract
The invention relates to a mineral concentration method of vanadium stone coal, which comprises that: using jaw breaker or hammer breaker to break large ores into 30mm ones; using ball grinder to grind the broken ors into 0.074mm (2-deals) ones to be made into ore pulp; using wet superfine classifier as hydraulic cyclone in small size (diameter) to classify the ore pulp, to make the overflow particles to 0.03mm below; the overflow part is the finished ore, which can be used to smelt ore and extract vanadium. The invention is environment friendly, which can reduce the producing cost, improve the vanadium yield, and improve the competitive power of outer steel industry.
Description
Technical field
The present invention relates to a kind of beneficiation method that contains the scherbinaite coal, belong to the category of non-ferrous metal ore technology.
Background technology
Vanadium is one of important source material of steel and iron industry.The vanadium resource of China mainly is vanadium titano-magnetite and contains the scherbinaite coal that wherein the contained vanadium of the latter accounts for 87% of China's vanadium gross reserves.Vanadium main tax in bone coal is stored among clay class mineral such as kaolin, illite, the mica, but raw ore is all directly used in vanadium extraction without ore dressing from contain the scherbinaite coal at present, though it has small investment, the simple benefit of equipment, but the one, the rate of recovery has only 30～50%, the 2nd, environmental pollution is serious, also is unfavorable for the comprehensive utilization of bone coal simultaneously.
Summary of the invention
The objective of the invention is to remedy the deficiencies in the prior art, for relevant industries provide a kind of from containing the technology that the scherbinaite coal obtains concentrate, it is actually the ore dressing direction of vanadium extraction from contain the scherbinaite coal.
Technical scheme of the present invention is to adopt the method for gravity treatment, (the former is generally 0.075～1mm because of granularity is different with clay class mineral to utilize quartz, the latter is generally below 0.02mm) and have the purpose that different sinking speed this point reach separation, this beneficiation method is characterised in that process route is as follows: (1) is crushed to lump ore less than 30mm with jaw crusher or hammer mill; (2) with ball mill breaking ores is milled to about 0.074mm promptly about 200 orders and make ore pulp; (3) with the fine graded machine of wet type for example the small size hydrocyclone ore pulp is carried out classification, make the overflow particle below 0.03mm, this moment, overflow portion was to be concentrate, and precipitation part is a mine tailing, concentration ratio generally can reach 5～10.
During concrete enforcement, also available fine grained of gained concentrate and ultra-fine grain sorting technology (for example add flocculant with flotation column and carry out flotation) are further selected.
The specific embodiment
Earlier the scherbinaite coal that contains from stope is crushed to less than 30mm with jaw crusher, be milled to about 0.074mm (200 order) with ball mill breaking ores again and be mixed with the suitable ore pulp of concentration, with small diameter hydraulic cyclone ore pulp is carried out classification subsequently, can carry out multistep treatment in case of necessity, be concentrate from what the hydrocyclone overfall came out, and being rough (mine tailing) from what the hydrocyclone spigot came out, concentration ratio can reach 5～10.The concentrate of gained can be directly used in the smelting vanadium extraction, and also available flotation column adds the method for flocculant with further enrichment; In addition, gained rough (mine tailing) can fully utilize again, for example is used to extract carbon, sulphur, silver, pyrite and barite etc.
Its benefit is fairly obvious after the invention process: the one, enlarged stock number, because V
2O
5Content utilizes all can obtain more than 0.1%, and the utilization rate of aluminiferous bone coal can reach 92%; The 2nd, to environmental protection with reduce production costs all very favourablely, because can concentrate smelting by ore dressing, production cost and environmental pollution will reduce greatly; The 3rd, the vanadium output of China also will increase substantially, and the steel proportion of high-quality also can greatly increase, thereby improve China's steel competitiveness in the international market; The 4th, carried on if contain the comprehensive utilization of scherbinaite coal mine tailing, also may make bone coal also become (contain carbon shale and be commonly called as bone coal) a kind of important mineral products and the energy of China.
Claims (2)
1, a kind of beneficiation method that contains the scherbinaite coal is characterized in that process route is just like following:
(1) lump ore is crushed to less than 30mm with jaw crusher or hammer mill;
(2) with ball mill breaking ores is milled to about 0.074mm promptly about 200 orders and make ore pulp;
(3) with the fine graded machine of wet type for example the small size hydrocyclone ore pulp is carried out classification, make the overflow particle below 0.03mm, this moment overflow portion be concentrate, concentration ratio can reach 5～10.
2, a kind of beneficiation method that contains the scherbinaite coal according to claim 1 is characterized in that, also available fine grained of gained concentrate and ultra-fine grain sorting technology are further selected, for example adds flocculant with flotation column and carries out flotation.
