Abstract
The analytical reagent dithiopyrilmethane (DTM) is investigated in combination with potassium butyl xanthate (PBX) in gold recovery from low-sulphide arsenical gold ore. Thanks to two heterocycling rings in the structure, DTM attaches to nonferrous and noble metals. Adsorption of DTM at arsenopyrite and gold is determined using the electron and laser microscopy, as well as by IR and IV spectroscopy. In flotation of arsenopyrite with nano gold, the PBX–DTM combination increases both the yield of pure arsenopyrite and arsenopyrite with nano gold. The DTM–PBX flotation of Olimpiada ore has improved the quality of the concentrate in terms of the gold content by 3 times at the simultaneous increase of gold recovery and proportional decrease of gold loss with tailings. These results prove advisability of using DTM in integrated gold recovery from arsenical gold ore.
