Problems solved by technology

There are mainly impurities such as non-metallic ore potassium, albite, aluminum, mica, etc., and metal ore hematite, limonite, siderite and pyrite. It is effectively removed; hematite, limonite, siderite and pyrite are not effectively and precisely removed; the non-metallic mineral impurities that are difficult to dissolve in acid are not effectively and precisely removed; the entire production process has a great impact on product quality stability Poor control, unstable product quality
The resulting SiO 2 The content is 99.9%, which is difficult to meet the application requirements of high-tech products

Embodiment 1

[0034] 100kg of vein quartz raw ore is laser crushed to separate the associated minerals from the quartz, meet the requirements of roasting particle size, and make the quartz particles break down into countless tiny holes; then the quartz particles are crushed into quartz sand, of which The diameter is 0.2~0.5cm. Then the above-mentioned quartz sand after electromagnetic roasting is placed in water to cool rapidly, so that the inclusions, bubbles, and water lines inside the minerals are quenched and burst, and the hardness of the minerals is reduced while water quenching, and then crushed to obtain a particle size of 200 -500 mesh quartz sand. Then the above-mentioned quartz powder rotates and slides along the surface of the chute, and uses gravity and centrifugal force to separate materials with different specific gravity, and then undergoes two magnetic separations with different magnetic field strengths. The first magnetic field strength is 2000 Gauss, and the action time i...

Embodiment 2

[0036] 100kg of vein quartz raw ore is laser crushed to separate the associated minerals from the quartz, meet the requirements of roasting particle size, and make the quartz particles break down into countless tiny holes; then the quartz particles are crushed into quartz sand, of which The diameter is 0.1~0.4cm. Then put the electromagnetically roasted quartz sand in water to cool quickly, so that the inclusions, bubbles, and water lines inside the minerals are quenched and burst, and the hardness of the minerals is reduced while water quenching, and then crushed to obtain a particle size of 500- 700 mesh quartz sand. Then the above-mentioned quartz powder rotates and slides along the surface of the chute, and uses gravity and centrifugal force to separate materials with different specific gravity, and then undergoes two magnetic separations with different magnetic field strengths. The first magnetic field strength is 2000 Gauss, and the action time is 20 minutes; the second ...

Finally, the obtained quartz tube, quartz plate or quartz rod has an SiO2 content up to 99.990-99.99990% and an impurity content of less than 10ppm.

Description

technical field [0001] The invention relates to a preparation method of a quartz tube, a quartz plate or a quartz rod, and belongs to the technical field of preparation methods of inorganic substances. Background technique [0002] Quartz, a term in geology, generally refers to low-temperature quartz (α-quartz), which is the most widely distributed mineral in the quartz group of minerals. Quartz in a broad sense also includes high-temperature quartz (β-quartz), coesite, and the like. Its main component is SiO 2 , colorless and transparent, often contains a small amount of impurity components, and turns into translucent or opaque crystals with a hard texture. Quartz is a mineral resource with very stable physical and chemical properties. The crystal belongs to the oxide mineral of the trigonal crystal system. Quartz block, also known as silica, is mainly the raw material for the production of quartz sand (also known as silica sand), as well as the raw material for quartz r...
