tion of gold ore low consumption

  • Silver Supply amp; Demand History JM Bullion

    It is interesting to note that the all time estimated mined Gold Silver ratio is about 8.8. This means that for every 8.8 ounces of silver mined we humans have mined up about 1 ounce of gold (based on the all time estimate of 1.5 billion tonnes of silver and 170,000 tonnes of gold mined).
