<p><P>PROBLEM TO BE SOLVED: To provide a chlorine leaching method for metal sulfides that can leach metal components out of nickel-mixed sulfides at a high leaching rate by efficiently promoting a chlorine leaching reaction without requiring additional costs for facilities or an increase in workload. <P>SOLUTION: The chlorine leaching method for metal sulfides performs chlorine leaching in a sulfide solution formed of metal sulfide as a raw material and including copper ion. The chlorine concentration of the sulfide solution is adjusted between 270 g/L and 350 g/L for the chlorine leaching. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
