The invention discloses an anti-corrosion technique for a normal-pressure reaction kettle for producing polyaluminium chloride, relates to an anti-corrosion technique, in particular to an anti-corrosion technique for a normal-pressure reaction kettle for producing polyaluminium chloride, and aims to provide an anti-corrosion technique for a normal-pressure reaction kettle for producing polyaluminium chloride with high anti-corrosion performance and long service life. The invention adopts a technical proposal that the normal-pressure reaction kettle for producing the polyaluminium chloride by the anti-corrosion technique comprises a kettle body and industrial acid-resistant magnetic plates, wherein the kettle body is made of bauxite, kaolin or calcium aluminate or mixture thereof, an adhesive for adhering the industrial acid-resistant magnetic plates is slurry of acid-resistant cement and calcium chloride or sodium silicofluoride and water, and the calcium chloride or the sodium silicofluoride accounts for 5 to 30 percent of the acid-resistant cement. The anti-corrosion technique is used for the normal-pressure reaction kettle for producing the polyaluminium chloride.

Quartz sand tailing mud recycling method
The invention discloses a quartz sand tailing mud recycling method which comprises the following steps: removing metal impurities in clay mud through water washing, removing magnetic metal impurities and strong magnetic ores in the quartz sand tailing mud through magnetic separation, breaking fluid inclusion and quartz crystal lattices through low-temperature crushing, exposing aluminum impurities in the fluid inclusion and the quartz crystal lattices, and removing the aluminum impurities through acid pickling. And for impurities such as aluminum and the like which are not removed in the feldspar, performing flotation on the feldspar by adopting a cation collecting agent through a flotation method, activating the feldspar and inhibiting the quartz by adopting sodium silicofluoride, and finally obtaining high-purity and high-yield quartz. The method can be applied to production of high-end products such as monocrystalline silicon, polycrystalline silicon, quartz glass, optical fibers, solar cells, integrated circuit substrates and aerospace materials.
