  • Process For Recovering Precious Metals From Sulfide Ores

    Feb 28 1990 The present invention is a process to recover precious metals from sulfide ores. It involves chlorinating a mixture of an ore concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300.degree. and 600.degree. C. while stirring. The process converts precious metals in the elemental and sulfide
