FIELD: mineral dressing. SUBSTANCE: collector- foamer designed for floatation of copper and complex ores contains still residues from rectification of 2-methyl-5-ethylpyridine, 0.5-50%; 2-methyl-5-vinylpyridine, 0.2-50% along with bottom fraction from butyric aldehyde production, 5-99%. Still residues of rectification chiefly contain nonpolymerized pyridine bases. EFFECT: enhanced floatation activity due to increased both collecting and foaming properties.
