  • A critical review on destruction of thiocyanate in mining

    Thiocyanate is produced during coking of coal and gold mining. Thiocyanate is toxic to several aquatic organisms. Toxicity of thiocyanate necessitates robust destruction techniques. Several bacterial species metabolize thiocyanate. Thiocyanate degrading bacteria can be exploited for effluent treatment.

  • Effect of arsenic on nitrification of simulated mining water

    Arsenic co occurs with ammonium especially in gold mining where gold is associated with arseno sulfidic minerals such as arsenopyrite ( Dave et al., 2008 ). The use of nitrogenous blasting agents, cyanide and ammonia as lixiviant for copper and nickel recovery are among the main sources of ammonium in mining effluents ( EPA, 2003 ).

    The toxicity of cyanide to aquatic life is probably caused by hydrogen cyanide that has ionized, dissociated or photochemically decomposed from compounds containing cyanide. Toxic effects of the cyanide ion itself on aquatic organisms are not believed to be significant, nor are the effects of photolysis of ferro and ferricyanides.
