100 g/t, while PAX was 71% at the same condition. The
flotation kinetics study showed that the collector 2-OA
displayed faster reaction speed and higher efficiency than
PAX. In the continuous two-stage flotation, the final cop-
per recovery for collector 2-OA was 69% higher than PAX
when only 100 g/t of collector was added in the roughing
stage. The copper grade for collector 2-OA can be improved
by 2 times through cleaning. Generally, the 2-OA collector
showed a superior flotation effect during the various flota-
tion conditions than PAX.
