Hello Masters.
I am here for a review of best refine process used for copper.

A nonferrous metal powder with
Cu 94%, tin 4%, lead 3%

Is any process where can i get refine all metal with chemicals composition?
 
Tin/lead has very low MP compared to copper. Therefore heating will liquefy them and leave most copper solid, easy to separate
