Sulphide Minerals • Are sometimes roasted –Heated in air without melting to transform sulphides to oxides –Gives off H 2S and SO 2 –Then oxides processed like Fe • Process of roasting and smelting together creates a matte –Sulfidesare melted into a matte and air is blown through. S is converted to sulfurdioxide and Fe to
crystalline structure of sulfide minerals such as pyrite and arsenopyrite. For cyanide to leach gold, the cyanide solution must come into direct contact with gold molecules. With many sulfide ores, the ore cannot practically be ground down fine enough to expose the gold particles. The objective of

viable, to process mineral resources very much depends on the type of ore which is mined as well as of the physical conditions linked to the location of the mine site. Heap leaching is a tried and tested mining technique enabling the processing of different kinds of ores which could not otherwise be exploited under viable economic conditions.

for the treatment of complex Sulphide ores involve Sulphide oxidation to form water soluble sulphates or oxides. The sulphur oxidation processes include roasting, pressure oxidation, chemical oxidation and bioleaching. The processes that are traditionally used are complex and expensive.
CARBON ADSORPTION RECOVERY. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution. The CIL process is frequently used when native carbon is present in the gold ore. This native carbon will adsorb the leached gold and prevent its recovery.
