Abstract: In this paper, the application of amine reagents in the flotation of phosphate rock, bauxite, iron ore, magnesite and lead-zinc oxide ore is summarized, and its electrical changes and adsorption properties of amine reagents and mineral surface are reviewed, and the amine collectors with different carbon chain lengths, different types and different substituent sites are compared.The practical application and mechanism of amine collectors were analyzed and summarized, and the development direction of amine collectors in the future was also prospected.
