Description
Technical field
The invention belongs to the deep process technology of quartz sand, particularly relate to the production method of a kind of glass sand.
Background technology
Quartz sand, also known as silica sand, is a kind of common nonmetallic ore raw material, and its application is quite varied.The quartz sand purification by mineral of China and deep processing development utilize ratio is later, and be mainly used in building industry, glass manufacture, ceramic industry and foundary industry, of these fields what is common is that quartz sand demand is big, feed quality requirements is low.For the high grade quartz sand in some places of production of China, substantially without purification by mineral or the most purified, industrial sand demand can be met.
At present, external the most advanced with the quartz sand purification by mineral technology of the U.S., feature is that industrialization yield is big, equipment is specialized and production automation degree is high, and its product has evolved to the 6th generation (impurity total mass fraction is less than 8 × 10-6, and transparency is optical grade).High-purity and the ultra-pure quartz sand made through purification by mineral is widely used to the high-tech areas such as Aero-Space, atomic energy technology, laser, fiber optic communications, military project.Along with the progress of science and technology, the demand of high-tech silicon also will roll up, and the increasingly exhausted of mineral crystal resource makes people have to turn to sight on the high-purity and ultra-pure quartz sand of succedaneum of mineral crystal.Therefore, actively seek and promote the progress of quartz sand purification by mineral technology, realize purity quartzite, the industrialized production low-costly and in high volume of high-purity and ultra-pure quartz sand, to making up the deficiency of mineral crystal resource, meet high-tech silicon demand and have important practical significance.Two patent documentations relevant to present subject matter are found through retrieval, but all there is complex process in the production method in these patent documentations, the problem that production cost is high, number it is the high purity quartz sand manufacturing method of CN 102887516 A as disclosed therein, although the quartz sand purity produced is high, but a word used in place name firing technique of twice, higher to process specifications, general enterprises is difficult to accomplish.
Summary of the invention
It is an object of the invention to provide the production method of a kind of glass sand, by quartz sand polish, controlling within 10ppm by quartz sand product total impurities, purity reaches more than 99.99%.
It is an object of the invention to be achieved through the following technical solutions, the production method of a kind of glass sand, its processing step is:
1, magnetic separation: by the quartz sand particle that smashing fineness is 80 100 mesh, uses dry-type magnetic extractor to carry out primary election, mainly removes garnet, bloodstone, limonite, ilmenite and intergrowth granule thereof, and suitable magnetic field intensity should be 10000Oe.
2, flotation: use H2SO4Adjusting agent, pH=2.5～3, petroleum sodium sulfonate makees collecting agent. and foaming agent made by orange alcohol oil, mainly removes the Muscovitum in quartz and Fe2。
3, classification, desliming: the present invention uses and adds the method that dispersant effective powerful is cleaned, to improve scrub effect.The purpose adding dispersant is to increase impure mineral and the electric repulsion on quartz particles surface, strengthening the separating effect that impure mineral is mutual with quartz particles, employing styrene acrylic is as dispersant, when dispersant dosage is 400-500g/t, when the scouring time is 15 25 minutes, its best results.Employing adds dispersant effective powerful and cleans technological process, obtains-0.6+0.1mm by graded desliming, the Fe in product203Less than 0.1% is dropped to, Sio from the 0.25% of raw ore2Content, also greater than 99%, has obtained good scouring refining effect, and washed ore productivity is also up to more than 73%.
4, acid leaching, washing: use the hot acid leaching method of two acidleach two washings, remove and separate the thin film ferrum of silica sand particle surface and the association iron mineral in quartz sand or iron-bearing mineral etc..Acidleach flow process is: mixed acid I leaching-washing-mixed acid II soaks-washs；
5, be dried: after two acidleach two washings, at 100-120 DEG C, be dried l5～20rain, just final glass sand.After tested, Sio2 content reaches 99.99%, and Fe content is≤2.35ppm.
The described hot acid leaching method using two acidleach two to wash in step 4 acid leaching, washing is:
1. the proportioning of mixed acid I is HCI:H2SO4=0.5:1, acidleach concentration is: quartz: mixed acid: water=100:35:40；Acidleach temperature is 38-42 DEG C, and leaching time is 6-10 hour；Washing after acidleach I, all uses tap water (washing 3 times).2. mixed acid II is HC1, H2SO4、HN03, HF, HF concentration be 8 10%, acidleach concentration is: quartz: mixed acid: water: 100:60:50；Acidleach temperature is 45～50 DEG C, and leaching time is 4-6 hour；Washing after acidleach II, first washs with tap water. when cleaning mixture is close to neutrality, then it is washed with deionized 3 times.
The invention has the beneficial effects as follows:
By magnetic separation, remove garnet, bloodstone, limonite, ilmenite and intergrowth granule thereof；The Muscovitum in quartz and Fe is removed by flotation2；Clean by adding dispersant, increase impure mineral and the electric repulsion on quartz particles surface, strengthen the separating effect that impure mineral is mutual with quartz particles；Particularly wash through two acidleach two, with acid, the dissolution of ferrum and other harmful element separated the thin film ferrum of silica sand particle surface and the association iron mineral in quartz sand or iron-bearing mineral.In a word, through above-mentioned strict processing step, highly purified quartz sand is produced.Whole production technology is reasonable, and production cost is low.
