This is a low-investment process that cuts hand picking labor in half. With its ability to eject both large and small copper meatballs and other copper bearing material, a ballistic separator typically increases copper pickings from 8 to 14 lbs. per ton. An average melt result for a ballistic separator is 0.16 to 0.17 percent copper.
