Pretreatment Process on Refractory Gold Ores with As

Chemical treatment is another branch of ore pretreatment and has the advantages roasting process doesn't have. Those are no difficult secondary leaching issues caused by under-burning and over-burning, well-adapted and selecting different reagents according to different ores. The process of chemical treatment is as show in Fig. 3.

The History of Ore Treatment Processes in Broken Hill

Treatment processes aimed mainly at the recovery of silver, lead being regarded as a by-product, and its recovery, except in so far as it affected silver recovery, was of minor importance. The first ore mined was carted to Terowie and thence railed to Melbourne, being smelted by the Intercolonial Smelting and Refining Co., of Spotswood.
