Processing Gold Ore by Flotation

Tests made on ore containing $9 gold, 3.5% copper, and 45% insoluble, showed that after crushing to pass 60 mesh and treating by direct flotation, an extraction of 82% of the gold and 96% of the copper could be obtained, with a concentrate containing only 21% insoluble. No doubt with finer crushing even better recoveries would be had. These results leave tables and vanners far behind. It was
