This procedure virtually eliminates the nugget effect, at least at finer particle size, and provides size-by-size total gold and GRG content. The non-GRG content is calculated based on the difference.

ROM ore is prepared for heap leaching by three stages of crushing – primary jaw crusher, followed by secondary and tertiary cone crushers, to give a product 100% minus 25 mm. The output from the primary crusher is passed over a 25 mm. Conclusions

The goal of refining is to produce gold that is at least 99.5% pure, if not higher. Achieving higher purity levels through refining gives gold several important advantages. For one, higher-purity gold is less prone to ...
