  • Optimising cyanideoxygen ratios in gold cip/cil circuits

    A method has been developed to optimise the cyanideoxygen ratio in gold CIP/CIL circuits. A gold (96%)/ silver (4%) alloy disc electrode is placed in the leaching pulp and its corrosion potential measured against a reference electrode.

  • The carbon in pulp process unitn.it

    Gold is washed (eluted) from the loaded carbon with a solution of cyanide and caustic soda, and then recovered by electrolysis or by precipitation with zinc dust. This method makes it unnecessary to filter the pulp and subsequently treat large volumes of dilute gold bearing solution.

  • CA1322658C Sulfide treatment to inhibit mercury

    Case 185 ABSTRACT In this invention sulfide compounds are added to mercury and precious metal containing carbonaceous ore slurries prior to the slurry being processed by a carbon in pulp system. The sulfide compound inhibits the mercury from being adsorbed onto the activated carbon by reacting with the mercury to form mercuric sulfide and by inhibiting the dissolution of mercury from the ore.
