<p><P>PROBLEM TO BE SOLVED: To provide a method which can attain lead treatment where all can be performed by a wet process. <P>SOLUTION: Disclosed is a method for leaching lead where lead sulfate in a lead-containing material is made into lead carbonate with sodium carbonate, and thereafter, the slurry concentration of the lead carbonate is controlled to 100 to 250 g/L, and the pH of a sulphamic acid solution is controlled to≤3.0, thus Pb can be leached by≥80%. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
