Abstract
The authors discuss application of nitrogen-oxygen-sulfur heterocyclic agents as collectors and frothers in flotation of sulfide minerals. Efficient collectors are the compounds which contain nitrogen heteroatom and sulfur atom in pendent group: they can generate complex compounds, including chelate, with copper, antimony and other metals in sulfide ore. Compounds containing sulfur heteroatom can modify sulfide surface, which favors attachment of collectors later on.
