  • Pyrometallurgical Recovery of Gold From Refractory Gold

    The problem concerning effective processing of gold ledge ores extremely refractory to loosening has been considered. [1]. Among gold ledge ores in Central Kazakhstan ores from the Sayak4 goldarseniccobalt deposit discovered in 1950s have not been processed until the present as they are extremely refractory to loosening and beneficiation.

    on a refractory gold concentrate. lime roasting of refractory precious metal ores. This study used hydrated lime to react with arsenic and sulfur under typical roasting conditions. The results showed more than 99.9% of the arsenic and 98% of the sulfur were retained in the calcine when roasting. Lime Roasting The problem with lime roasting for industrial application is that the arsenic
