Abstract
The models of sulfide minerals (covellite, bornite, chalcopyrite and pyrite) are developed. The molecular models of thionocarbamates containing electron-accepting (O-butyl-N-ethylcarbamothioate (BETC)) and electron-donating (O-butyl-N-benzoylcarbamothioate (BBTC)) radicals bonded to nitrogen atoms are built. The interaction reactions between thionocarbamates and sulfide minerals by bidentate bond are reviewed to form a complex such as MeSN or bidentate complex with coordinated CuSNH and retained hydrogen/nitrogen bond. The paper offers a forecast of O-butyl-N-benzoylcarbamothioate (BBTC) and O-butyl-N-ethylcarbamothioate (BETC) activity estimation (PEC) in reactions with copper minerals and pyrite and shows that it is more energy-efficient to form a complex with coordinated CuSNH.
