The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon (typically 1000-4000 g/t). At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and cyanide solutions to form a high value electrolyte solution.

Typical specifiions for this autoclave feeding are pressures of more than 40 bar, high solids concentrations, low pH-values and operating temperatures up to 230 °C.

Utilization of walnut shell as a feedstock for preparing …

Abstract The present work attempts to convert walnut shell into a high surface area activated carbon by microwave heating and chemical activation. Different activation agents such as KOH, NaOH, K 2 CO 3 and Na 2 CO 3 were utilized to identify a suitable activation agent. The result indied that KOH was the most suitable activation agent among those agents, with the highest porosity and
