Jul 13 2016 Where a high sulphide recovery is demanded flotation methods are now in general use but in the days before flotation was known a large part of the worlds gold was recovered by concentrating the goldbearing sulphides on tables and smelting or regrinding and amalgamating the product Though the modern trend is away from the use of tables because flotation is so much more a higher content of organic carbon which results in difficulty in the recovery of gold In this study the flotation gold concentrate before and after pressure oxidation POX was analyzed The analysis of the EhpH diagram revealed that pyritearsenopyrite would be dissolved in higher oxidation potential
