Roasting of Gold Ore in the Circulating Fluidized-Bed .

1/1/2016· The ore contains on average 1.1% sulfide sulfur, 1.1% organic carbon and 2.9% carbonate carbon. The relatively high carbon content affects the gold recovery through preg-robbing during leaching. After roasting in the CFB, the carbon content is reduced to such low levels that the gold recovery increases by approximately 20%.
