Liu, Guang-yi published the artcileReverse flotation separation of diaspore and kaolinite in the presence of cationic polyacrylamide polymers, HPLC of Formula: 2016-56-0, the publication is Transactions of Nonferrous Metals Society of China (2003), 13(5), 1231-1234, database is CAplus.
Based on the crystal structure and surface properties of diaspore and kaolinite, an effective diaspore depressant, CPAM (cationic polyacrylamide) was identified based on single mineral tests, separation of synthetic mixed minerals, zeta potential, and adsorption measurements. The reverse flotation separation of diaspore and kaolinite can be carried out using dodecylamine acetate as collector and CPAM depressant at pH 5.5-8.5. The diaspore particles show large amount of active aluminum atoms that can bond with -C(O)NH2 groups in CPAM and the -CH2N+(CH3)3 groups in CPAM orient toward the outer surfaces of diaspore and prevent a majority of dodecylamine cations from adsorbing on diaspore, enhancing hydrophilicity of diaspore, and depressing floatability of diaspore particles. As for kaolinite, CPAM polymers have little effect on floatability.
