US5074910A - Process for recovering precious

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° and 600° C. while stirring. The process converts precious metals in the elemental and sulfide forms into

EXTRACTING METALS FROM SULFIDE ORES

EXTRACTING METALS FROM SULFIDE ORES. Many important metals are present in nature combined with sulfur as metal sulfides; these include cadmium, cobalt, copper, lead, molybdenum, nickel, silver, and zinc. In addition, gold and platinum group metals are associated with sulfidic base metal ores. The extraction of metals from their ores has been an

Recovery of Gold in Pyritic Sulfide Ores - Mine

Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently
