Activation mechanism of lead ion in the flotation of stibnite
The flotation of stibnite with Pb 2+ as an activator was examined with micro-flotation tests, inductively coupled plasma mass spectrometry (ICP-MS) experiments and density functional theory (DFT) calculations. It was found that at a pH of 6.5, the addition of Pb(NO 3) 2 notably improved the flotation efficiency of stibnite with butyl xanthate (BX).
