Mineral processing can involve four general types of unit operation: 1) Comminution – particle size reduction; 2) Sizing – separation of particle sizes by screening or classification; 3) Concentration by taking advantage of physical and surface chemical properties; and 4) Dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics

2010722· Haven''t done anything chemical yet to them. I sat down, make some research on common copper and gold thickness on PCBs, played with data on Excel and find that Molality-wise there''s way too much copper against gold in most configuration of copper/gold thickness. I find that seperating copper from gold using HNO3 is quite costly.
