  • Activated Carbon movement study in gold CIL or CIP circuit

    In carboninpulp (CIP) or carboninleach (CIL) systems it is necessary to obtain a sample from the agitated mix of carbon and pulp Wetted carbon will settle (sp gr 135) in water Thus a complex situation involving pulp rheology (sp gr, viscosity, and % solids), carbon particle parameters (size, density, and shape), and agitation dynamics determines the suspension ofIn my first gold mine we noted that the solution plus solids gold leaving the leach circuit was 2/3rds of what was entering This soon resulted in suggestions of massive theft by us, the mill crew The first time that we had to drain a tank I went to the bottom with a camera, a sample bag, and a measuring tape The settled solids formed a hemisphere for a tank bottom and gradedHow do I account for gold in circuit GIC HydrometallurgyIf Degussa's cyanidation technique is applied to a conventional gold plant and the leaching time can be reduced from 2448 hours using compressed air to 1836 hours using H2O2, the overall gold output may be increased by 210 percent absolute This also results from the faster extraction kinetics using H2O2, since the retention time of the pulp in the plant is characterizedHydrogen Peroxide in CIL Gold Leaching Circuit
