Refractory gold ores have poor gold recoveries with direct cyanide leaching Typically the refractoriness is due to encapsulation of the gold particles inside the host mineral To liberate gold for leaching the host mineral must be broken by mechanical or chemical means
Alternative lixiviants include bromides acid and alkaline chlorides and thiosulfate The lower sensitivity to base metals As Pb Cu Sb Zn or impurities render possible the use of this process on many refractory gold ores Thiourea leaching has been tried on different materials and ores with success
Process Introduction Refractory Gold Ore Processing is an efficient method to process refractory gold directly using conventional cyanidation methods the recovery rate of gold is low So pre treatment of refractory gold ore is added to the processing line which increased improve enterprise production benefit
They said it had a lot of silver and copper but no gold A geologist said that the fire assay may not have extracted the gold from the ore because of the various gold silver copper sulfur refractory compounds within due to a limited process that was used This type of ore requires more extensive process steps to reduce the gold
