 · Later cyanide leaching has been operated in various modes heap leaching, CIP (carbon in pulp), CIL (carbon in leach), and RIP/RIL (resin in pulp/leach) (Marsden and House, 2006). The environmental hazards and toxicity of cyanide have increased the interest in a new cyanidefree gold process (Aylmore, 2005).

 · Activated carbon also consumes cyanide, so its effect has to be accounted for in the case of carboninleach (CIL) or carboninpulp (CIP) plant flowsheets. Since cyanide is an expensive reagent, often a major component of plant operating costs, it is important that the scaleup of cyanide consumption from laboratory to plant be representative. The traditional method of reporting cyanide ...
