<p><P>PROBLEM TO BE SOLVED: To provide a method by which lead removal can be attained while dispensing with expensive special equipment, without decreasing alloy components even in the case of a tin-containing copper alloy. <P>SOLUTION: In the method for removing lead from a copper alloy, the copper alloy is melted and a tin-blocking agent is added to the resultant molten copper alloy to undergo mixing to inhibit tin in the copper alloy from being combined with a deleading agent. Subsequently, the deleading agent is added to undergo mixing, and the deleading agent is combined only with lead in the copper alloy and the resultant lead compound is floated and separated. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
