Description
Technical field
The present invention relates to mineral to utilize technical field, particularly relates to a kind of method of comprehensive utilization of granite.
Background technique
Granite is the significant rock in continent, is the basis for constituting continent upper crust, it can be seen that the storage of granite
Amount is abundant, and most of granite is due to lacking effective development and utilization, at present still in state to be developed, even if having small part
Also it is only cut, polishing for selectivity through developing and using, is used as the foundation stone, square brick or the rank built of road
Stone.These products not only bad environments in the production process but also product matter produced is honest and clean at a low price, added value is not high,
Result in waste of resources it is serious, hidden danger is also constituted to ecological environment.
Granite is main still by quartz and orthoclase and microcline and other impurity components although complicated component:
Hornblend, tourmaline, mica etc. are constituted.And the utilization and exploitation of single quartz, spectra, domestic technique more at
It is ripe, and granite is rarely had as a kind of research that mineral are comprehensively utilized and report and is heard of.Analyze its reason, it may be possible to
Using granite only as a kind of Mineral pairs as being compared with quartz, SiO2Content is inadequate to be compared with feldspar ore, K2O、Na2O and Al2O3
Content is again relatively low, and the requirement of downstream product is not achieved in impurity content exceeding index, whiteness.According in its mineralogical composition based on feldspar
The characteristics of, it, not only can be because of mica in granite if removing mica using flotation using the method for previous feldspar ore conventional purification
Content is higher, causes reagent cost high, environmental protection pressure is big.In addition similarly there is difficulty in the separation of feldspar and quartz.Thus, to the greatest extent
Pipe rich reserves, but the domestic research to granite comprehensive utilization is still in blank.
Quartz, feldspar, mica occupy very important position in entire nonmetallic ore, their application is related to building
It builds, ceramics, electronics, the various fields such as space flight allow if can be effectively separated quartz, feldspar and the mica in granite
They have respectively entered respective field and make the most of the advantage, and will be major issues that part is benefited the nation and the people.

The vertical strong magnetomechanical of ring, removes weak magnetic mineral, obtains black quartz concentrate, weak magnetic mineral and strongly magnetic mineral, which merge, becomes magnetic mine
Object one；
(5) that step (3) color sorting is obtained red feldspar is rough, by ball mill ore grinding, then passes through hydraulic classifier and hindered settling
Device controls material size between 60-120 mesh, after the overflow concentration of hydraulic classifier, is sieved by high frequency shale shaker, on sieve
Material is fine fraction mica one, and lower sieve is fine fraction feldspar one；Fine fraction mica one and fine fraction feldspar one pass sequentially through vertical ring
Magnetomechanical grade magnetic separation removes mixed machinery iron and strongly magnetic mineral, biotite, tourmaline and weak magnetic in mineral process respectively
Property mineral, product after magnetic separation obtains high potassium feldspar concentrate, the institute that magnetic separation obtains by concentration, band filter filtering, drying
The mineral that are magnetic merge, and become magnetic mineral two；
(6) screenings for the rough -1mm obtained with step (1) of white feldspar that step (3) color sorting obtains is mixed, passes through ball milling
Machine ore grinding recycles hydraulic classifier and hindered settling device to control material size between 60-120 mesh, hydraulic classifier
It after overflow concentration, is sieved by high frequency shale shaker, on-the-sieve material is fine fraction mica two, and lower sieve is fine fraction feldspar two, particulate
Grade mica two and fine fraction feldspar two pass sequentially through vertical ring magnetomechanical grade magnetic separation, remove mixed machinery in mineral process respectively
Iron and strongly magnetic mineral, biotite, tourmaline and weak magnetic mineral, the product after magnetic separation pass through concentration, band filter mistake
Filter, drying, obtain potassium sodium anemonsite concentrate, and all magnetic minerals that magnetic separation obtains merge, and become magnetic mineral three；
(7) fine fraction mica two obtained in fine fraction mica one, fine fraction feldspar one obtained in step (5) and step (6),
Dust caused by during fine fraction feldspar two and crushing and screening, dry type magnetic separation, color sorting, which merges, becomes fine particle stage material, will
After fine particle stage material mixing, add water with slurry, by agitator stirring, homogenizing, successively using magnetomechanical, vertical ring high intensity magnetic separation in vertical ring
Machine, slurry formula magnetic separator magnetic separation purification obtain fine fraction using plate and frame filter press filters pressing, drying after the product concentration after magnetic separation
Feldspar concentrate, all magnetic minerals that magnetic separation obtains merge, and become magnetic mineral four；
(8) magnetic concentration for obtaining magnetic separation mineral two that magnetic separation mineral one that step (4) obtains, step (5) obtain, step (6)
It after the magnetic separation mineral four that object three and step (7) obtain merge, is concentrated using thickening cone, after vibrating screen dehydration, concentrates and stack, as
Cement plant, brick field ingredient.
2. the method for comprehensive utilization of granite according to claim 1, it is characterised in that: dry type magnetic in the step (2)

3. the method for comprehensive utilization of granite according to claim 1, it is characterised in that: the neutral ring of the step (4) is strong
Magnetomechanical background lectromagnetism field is 1.5T.
4. the method for comprehensive utilization of granite according to claim 1, it is characterised in that: the step (5) and step (6)
Middle ball mill is all made of quartz ball and quartzy liner plate, and the background lectromagnetism field of vertical ring magnetomechanical grade magnetic separation is followed successively by 0.4T, 1.0T and 1.5T.
5. the method for comprehensive utilization of granite according to claim 1, it is characterised in that: in the neutral ring of the step (7)
Magnetomechanical magnetic field strength is 0.4T, and Verticle ring high intensity magnetic separator magnetic field strength is 1.3T, and slurry formula magnet separator magnetic field intensity is 1.3T.
