Flotation activity of amino alcohols and their derivatives

Results are presented from experimental studies conducted to find derivatives of amino alcohols that can efficiently replace oxal T-80 in the flotation of complex ores: derivatives of 1-, 2-aminoethanol, 1-, 2-, and 1-, 3-aminopropanes, and 3-, 4-substituted amino alcohols of the pyridine and piperidine series.
