For an agitated leach plant processing 2 g/mt gold ore, it requires a production rate of at least 5,000 mt/d of ore. Even in those cases, while the Carbon Converter has a payback of about one year, but it does not significantly move the economic needle since it increases gold production only 1% to 1.5%."
