ABSTRACT In the evaluation of ore bodies for precious metal content, rock and drill core samples are analyzed for the precious metal of interest. The analyses are most commonly carried out by a technique of smelting called fire assaying. There are drawbacks in this procedure which arises mainly from quantity of sample material used for the analysis or fire assay step. In the Total Gold CGL technique (also referred to as Casmyn CGL technique), the statistical error, associated with sub- sampling the rock and drill core samples is removed by taking the entire sample for processing and analysis. The CGL technique consists of grinding the sample in an inert grinding medium and simultaneously dissolving the precious metal present by a lixiviant which is pH controlled. The apparatus consists of a jar mill lined with a hard ceramic- like material and a ceramic ball charge. The lixiviant is essentially a sodium cyanide solution which is pH controlled. The precious metal content is evaluated by analysis of the two phases of a homogeneous slurry: The total gold content of the sample is computed from a metallurgical balance.
