Determination of Surface Gold Preg-Robbed on Carbonaceous Matter From Autoclave Pressure Oxidation (Ac Pox)/Carbon in Leach (Cil) Stream Products - Surface Science Western

Request for analysis: A refractory sulphide ore containing carbonaceous matter has been processed in an AC POX/CIL test plant. The gold recovery after cyanidation leaching is low. The CIL residue was analysed for possible losses due to preg-robbing of gold from the cyanide solution onto carbonaceous material present in the sample. Objectives: Methodology: Results of the study: Separate carbonaceous particles from the CIL residue sample were selected under the optical stereoscope and mounted on..
