  • The leaching and adsorption behaviour of gold ores Minerva Access

    There are many nonidealities in gold processing which are becoming increasingly important as simple freemilling oxide ores are depleted. During cyanidation and adsorption onto activated carbon, these effects include competing metalcyanide complexes, pregrobbing and the mineralogy of the ore. This thesis considers
