Although each ounce of gold recovered requires the processing of about 100,000 ounces of ore, there is so much gold deposited in rock veins that this method accounts for more than half of the worlds total gold production today. The gold in the veins may be of microscopic particle size, in nuggets or sheets, or in gold compounds.
