METHOD FOR CONCENTRATING AND RECOVERING NOBLE METALS
One aspect of the present invention provides a method for concentrating and recovering noble metals through a boron compound including, crushing a copper-containing material and preparing a mixture by mixing the same with a gold concentrate (step 1); oxidizing and roasting the prepared mixture by heat-treating (step 2); melting the oxidized and roasted mixture, and adding a boron compound in to a slag that is generated (step 3); and separating and recovering the slag and crude metal obtained in said step 3 (step 4).
