Description
Technical field
The present invention relates to low iron-stone sand purification field, particularly relate to a kind of low iron-stone sand and glass sand floatation process and with the use of floating agent.
Technical background
Solar-photovoltaic technology is the technology converting solar energy into electric power, and the glass substrate of solar photovoltaic generation system needs to use ultra-clear glasses, and ultra-clear glasses substantially increases photoelectric transformation efficiency with the high transmission rate of its uniqueness (91.5%).Photovoltaic glass requires high to impurity content, light transmittance, microdefect etc. because of the environment for use of himself finished product, and the quality requirement of the low iron glass sand (accounting for 60-70%) of its main material PPM level is extremely strict, the chemical analysis that General Requirements reaches: SiO
2(99.5%), Fe
2o
3(80PPM).In order to high efficiency, low cost produces the low iron glass sand of satisfactory PPM level, need existing production technology upgrading, the floating wash agent of improvement.
The low iron glass sand of PPM level, can be used for equally producing high-grade ware glass, quartz ampoule and polysilicon etc., has a extensive future.
Summary of the invention
The object of this invention is to provide the low iron-stone sand of a kind of PPM level and glass sand floatation process, the quality of quartz sand can be increased substantially, the growing quality requirements problem in market cannot be met with the production solving current China quartz sand.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of PPM level low iron glass sand floatation process, comprises the following steps:
(1), the quartz sand raw material of tcrude ore mechanical crushing after desliming, classification, magnetic separation of mining gained is sent in the first mixing cirtern, stir, regulate ore pulp PH to 6.0-7.5;
(2), by the ore pulp that step (1) is handled well send into the second mixing cirtern, in mixing cirtern, add floating agent, stir and make its abundant hybrid reaction;
(3) ore pulp, by step (2) handled well sends into the 3rd mixing cirtern, in the 3rd mixing cirtern, add terpenic oil, stirs and in fact mixes, then sent in flotation device by ore pulp and carry out flotation;
(4), by the essence sand floatingly selected send into washed ore pond, squeeze in upper strata desliming bucket through Pulp pump, slough floating agent, then flow into lower floor's desliming bucket, add clear water, washed ore is rinsed well, squeeze in washed ore storehouse;
Between the composition of described floating agent and each composition by weight ratio:
Mixed amine 25-30%
Petroleum sodium sulfonate 5-7%
Aliphatic acid 25-30%
Diesel oil 30-35%.
The reagent regulating PH in step (1) is 5%H
2sO
4or NaOH solution.
In described step (2), quartz sand raw material flotation medicament addition per ton is 2kg.
In described step (3), raw material terpenic oil addition per ton is 0.102kg.Use the floating agent of this concentration and terpenic oil obviously can promote the effect of flotation.
A kind of floating agent, between its composition and each composition by weight ratio:
Mixed amine 25-30%
Petroleum sodium sulfonate 5-7%
Aliphatic acid 25-30%
Diesel oil 30-35%.
The theoretical foundation of various floatation process is substantially identical, and namely ore particle is because of the hydrophobic property of its own face or hydrophobic (close gas or oil) characteristic of obtaining after floating agent effect, can assemble at liquid-gas or water-oily interface.Most widely used is at present froth flotation method.Ore makes various mineral disaggregation become monomer particle through broken with grinding, and makes granular size meet floatation process requirement.Add various floating agent to the ore pulp after ore grinding and stir mediation, making and mineral grain effect, to expand the intergranular floatability difference of different minerals.The ore pulp mixed up sends into flotation cell, stirs inflation.Ore particle in ore pulp and bubble contact, collision, the ore particle that floatability is good optionally adheres to bubble and is carried to rise becomes the mineralized froth layer of airwater mist cooling composition, overflows through mechanical scraping or from mineral slurry level, then dewaters, is dried to concentrate product.The mineral grain such as floaty gangue, does not discharge as product from failing bottom flotation cell with ore pulp.Another by useless mineral grain emersion, valuable mineral particle is stayed in ore pulp, is called reverse flotation, as emersion quartz etc. from iron ore.
Usual foam flotation is suitable for the ore particle sorting 0.5mm to 5 μm, and concrete grain limit is depending on mineral.Special method for floating need be adopted when selected granularity is less than 5 μm.If flocculation-flotation makes the valuable mineral of particulate flocculate into larger particles with flocculant, float again after deviating from the thin mud of gangue and remove coarse grain gangue.Carrier flotation makes carrier with the ore particle that granularity is suitable for flotation, makes fine mineral particle adhere to carrier surface and sorting of thereupon floating.Also useful oils makes the reunion of thin ore particle carry out oil aggregation flotation and the emulsion floatation of flotation; And utilize high-temperature chemical reaction to make Gold in Ores belong to the segregation flotation etc. of Mineral Transformation for flotation again after metal.During with metal ion in froth flotation recycle-water solution, first chemically precipitate or spent ion exchange resin adsorbs, and then flotation sediment or resin particle.The material of process in molecule, ion and colloid size, adopts offscum to be separated.Be characterized in the hydrophobicity utilizing some material, slowly stir and inflate on a small quantity, make into offscum and be gathered on the water surface and scrape.As reclaimed grease, protein, paper pulp and chemical products etc. from water.Ion flotation be can occur to precipitate with ion or complexing surfactant effect under, make reaction product enter offscum, complete sorting.
The quartz sand flotation method that the present invention relates to is easy to realize, simple to operate, the flotation of quartz sand fast and effeciently can be realized by method for floating of the present invention and floating agent, and then improve the output capacity of high-quality quartz sand, and greatly reduce the production cost of high-quality quartz sand, also reduce the labour intensity of operating personnel.
Accompanying drawing explanation
Fig. 1 is production technological process of the present invention.
