Abstract:Aiming at the problem of hydrogen sulfide exceeding the standard in the mineral processing operation of one Copper Mine in Anhui province , the prevention and contral scheme of “source contral and end treatment” was put forward. The paper mainly studies the causes of the occurrence of hydrogen sulfide, analyzes the mechanism of hydrogen sulfide generation, and proposes different prevention and control measures for different hydrogen sulfide generation points. The hydrogen sulfide prevention and control scheme has the characteristics of strong operability and high efficiency, and has certain reference and guiding significance for the prevention and control of hydrogen sulfide gas in related non-ferrous metal mines.
