Description

A kind of gravity ore dressing method of particulate antimony oxide ore
Technical field
The present invention relates to a kind of gravity ore dressing methods, and in particular to a kind of gravity ore dressing method of particulate antimony oxide ore.
Background technique
Antimony Oxide Ores are the important source materials of antimony product production, and shared specific gravity is quite big in China's antimonial resources, In the produced antimony ore in tinnery North, the content of antimony trisulfide and antimony oxide respectively accounts for 50%.Study the efficient of antimony oxide ore ore dressing Recycling is of great significance to the utilization rate for improving China's antimony resource.
The ore dressing of Antimony Oxide Ores especially particulate Antimony Oxide Ores is recycled, and is the problem in the outer ore dressing field of Now Domestic One of.For many years, it although having conducted extensive research both at home and abroad, does not make a breakthrough.Industrial application is still with weight at present It is selected as leading, but the rate of recovery of jigging, shaking table operation is low, and is difficult to recycle particulate oxide ore.Domestic ore dressing worker is centrifuged Ore separators adds belt chute, and runout belt chute, spiral chute, tower swivel chute etc. handle the research of antimony oxide thin mud, as a result It is undesirable.A kind of beneficiation method and process equipment for particulate antimony oxide ore high efficiente callback is found, to obtain optimal warp Ji benefit and social benefit are an urgent demands of antimony mineral ore dressing field.
CN104226463A discloses a kind of high tin-polymetallic sulphide ore beneficiation method, and this method is using outstanding vibration conical surface disk The mineral of ore separators recycling are stanniferous sulphide ore;Its ore pre-classification is using spiral classifier and large tilting plate board concentrating box point Grade concentration;But rough concentrate also needs table concentration, the ore size fraction range of processing is 10~40 μm, relatively narrow.
Summary of the invention
The technical problem to be solved by the present invention is to overcome drawbacks described above of the existing technology, provide a kind of ore dressing time High income, high production efficiency, low energy consumption, the gravity ore dressing method of the particulate antimony oxide ore of operating environment close friend.
The technical solution adopted by the present invention to solve the technical problems is as follows: a kind of gravity separation side of particulate antimony oxide ore Method is the antimony oxide raw ore after selecting antimony tailing or grinding, first removes coarse-grained material with Vibration Screen, then removed with hydrocyclone Sludge, last material are once sorted from suspended vibrating concentrating machine with conical surface is flowed into, and obtain antimony concentrate and true tailings.
Preferably, the antimony oxide raw ore is antimony oxide ore or sulphur and oxygen mixed antimony ore.Described that antimony tailing is selected to refer to, ore dressing is raw The low-grade floating (weight) containing antimony discharged in production selects the tailing containing antimony and low-grade antimony oxide ore object of tailing, Tailings Dam stockpiling, antimony oxygen Rate reaches as high as 100%.
Preferably, the tailing or to grind the fineness of rear raw ore be mass content under 200 meshes is 50~75%(more excellent Select 55~65%), grade containing antimony is 0.3~1.2%, antimony oxygenation efficiency >=85%.
Preferably, the coarse-grained material that the Vibration Screen removes is 200 mesh oversize of fineness.The part oversize grade is low, Or more preferably recycled using other preparation equipments, and containing sundries such as wooden slags, if will affect sorting result into subsequent process.
Preferably, the sludge of the hydrocyclone removing is 800 mesh screenings of fineness.If the part screenings enters outstanding The rate of recovery that vibrating concentrating machine with conical surface will lead to antimony is low, and interferes ore dressing process.
Preferably, the rotational frequency of the suspended vibrating concentrating machine with conical surface is 8~12Hz, 15~25Hz of vibration frequency, treating capacity For every 400~800kg/h.The suspended vibrating concentrating machine with conical surface of the preferred model DSLXZ-4000 of suspended vibrating concentrating machine with conical surface.Outstanding vibration Concentrating machine with conical surface is to shear loose theoretical and film concentration as the gravitational separation equipment of theoretical foundation, especially suitable for fine using Bai Genuo Grain metalliferous mineral sorts.After the method for the present invention first pre-processes raw material, is separated, then select the equipment it is described rotation or It is sorted under vibration frequency, obtains preferable mineral processing index.
It is highly preferred that the rotational frequency of the suspended vibrating concentrating machine with conical surface is 10Hz, 18~20Hz of vibration frequency, treating capacity is Every 550~750kg/h.
The method of the present invention will contain low-grade antimony ore object or antimony tailing is selected first to be carried out with high frequency vibrating fine screen and hydrocyclone Pretreatment, then sorted with suspended vibrating concentrating machine with conical surface, the recovery rate in ore-dressing of final gained antimony concentrate may be up to 49.25%, grade Up to 20.0%, recovery rate in ore-dressing is high, and high production efficiency is easy to operate, labor intensity, energy consumption and at low cost, operating environment friend It is good.
