Step #6 – Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done.
