Abstract	To gain the efficient and optimized application of agents MTH and ETH belonging to dithiazinanes to float gold from complex ores the investigation was undertaken on complexing conditions in water environment and at pyrite surface with manually attached gold (FeS$_{2}$Au) prior to flotation tests. The microscopic and spectral analysis of (FeS$_{2}$Au) surface after contact with MTH and ETH show the presence of organic S- and N-containing compounds. It is found that selective gold recovery from a gold-bearing material in flotation with MTH and ETH is conditioned by a number of factors that accelerate formation of poorly soluble compounds at the surface of gold particles. The analysis includes the contact time, optimal medium alkalinity, formation of an oxidized film at Au0 particle surface, introduction of modifying agents as additional ligands as well as mechano-chemical acceleration of the complexing. Mechano-chemical treatment with feeding a low soluble agent into a mill before flotation of copper-sulfide gold-bearing ore enabled to higher gold recovery into rough and intermediate flotation concentrates by 15.9 and 4% respectively. In this case Au content in tailings was lowered by 0.15 g/t as compared to flotation experiments with butyl xanthate and its combinations with ETH.
