Embodiment 1

[0015] 50 g of NiPAM and 80 g of DMAPMA were dissolved in 200 grams of deionized water, mixed uniform, stir up to 80 ° C, slowly added aqueous potassium sulfate solution containing 1 gram of the initiator and containing 0.5 grams promoter monohanolamine. Aqueous solution, insulation reaction for 2 hours. In the reaction, in order to eliminate the effects of illumination and oxygen on polymerization, the entire device is wrapped with an aluminum foil paper, and nitrogen protection is performed on the reaction system. After the end of the reaction, the temperature was lowered to normal temperature, and the obtained copolymer was transferred to the dialysis bag, the dialysis temperature was 30 ° C, and the continuous dialysis time was 8 hours. Finally, the polymer solution was diluted to 500 ml to 500 mL as a catch agent.

Abstract

The invention provides a cationic temperature-sensitive collector, which is used for Li 2 The flotation of ore with O content of 1.2‑1.8% mainly comes from the flotation of cave mining lepidolite ore. The cationic temperature-sensitive collector uses two monomers, N-isopropylacrylamide (NIPAM) and N-[3-dimethylaminopropyl]methacrylamide (DMAPMA), through free radical polymerization. The method is prepared by copolymerization, and the molar ratio of the two monomers is 1:5-8:1. The as-prepared cationic temperature-sensitive collector, for Li 2 The flotation of ore with O content of 1.2-1.8% is mainly derived from the flotation of cave-mined lepidolite ore, which has a better flotation effect.

Description

Technical field [0001] The present invention belongs to the field of mineralization engineering, and is specifically related to the preparation method of fine particulate lithium mica flotation. Background technique [0002] Jiangxi Yichun Tuan Rys Mine is the world's largest companion lithium mercury deposit, rich in lithium mica, 铷,, is one of the major lithium resources developed by China, which can open the lithium oxide content of 1.1 million tons, accounting for China's 31%, 11% of the world. With the continuous mining of lithium mica resources, Li2O content is less and less, and the mine is less and less, and the kind of mine is derived from the surface process, easy to flot it to Li. 2 The O content is 3.0% or more. More and more is a mine, Li, lithium mica characteristics, Li 2 The O content is 1.2-1.8%, which is derived from the cave process. This mine is buried in the depths of millions and ten meters, which is extremely difficult to float. The reason is that the lithi...
