The present Invention provides a method for leaching Gold from a Gold ore containing pyrite.It provides a method for leaching Gold comprises a pretreatment Stage 1 includes: a step of preparing the Gold ore containing pyrite and a step of Heating the Ore under an Inert atmosphere to personnel Working for pyrolyzing and pyrite in the Sulphide ore Iron (ii) and elemental Sulfur; a Step 3 of solid-liquid Separation,That is in contact with the Gold ore leaching of pretreated with a solution of Iron containing one or more selected from sulfuric acid, hydrochloric acid and an aqueous solution of Fe3 + salt to Leach the component content in Iron Ore andThe resulting solution is then subjected to a solid-liquid Separation to obtain a solution of Iron and a Post leaching residue leaching Step 4: a, which is in contact with the rcsiduo from Step 3 with a Solution containing Halide ions iixiviacion Gold,Copper and Iron ions inoes while supplying an oxidizing Agent to Leach Gold Component content in The residue and a step 5: regeneration of the leaching solution of Iron. To remove the Iron precipitates and component of post Iron leaching Solution obtained in the Step 3 as a form of oxihidroxido Iron.
