Pyrometallurgical Processing of Secondary Lead Material: …

Known lead ore reserves are approximately 85 million tons ... Thermal refining of soft and hard lead represent 90% of the world's lead refining capacity. Removal of copper nickel, arsenic, antimony and tin from the bullion is achieved by temperature control and addition of various reagents such as caustic, sulfur or air to …

Gold processing

Gold processing - Refining, Smelting, Purifying: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present …
