Micro-flotation tests were employed to assess the influence of CuSO 4 and Pb(NO 3) 2 on the flotation of stibnite. Without any activator, the recovery was only 63.27% with 110-5 mol/dm3 of BX (Fig. 2). Adding CuSO 4 or Pb(NO 3) 2 into the slurry favored the flotation of stibnite. With 510-5 mol/dm3 of CuSO 4, the recovery reached about 75%.

This is a tricky separation since both stibnite and arsenopyrite require activation to float successfully. So after activation, both minerals will tend to float. Presumably the significantly greater abundance of stibnite would consume most of the activator but no doubt there would be enough remaining to float any unoxidisedarsenopyrite.
