A Tof-SIMS analysis of the effect of lead nitrate on rare ...

2021-1-15 the ﬂotation behaviour of each rare earth bearing mineral is not clear. Furthermore, its particular role as an activator of these phases or any other REE phase is not clearly understood. Based on a literature review, lead nitrate works as an activator in the ﬂo-tation of pyrite and sphalerite, with an activation process often

A Tof-SIMS analysis of the effect of lead nitrate on rare ...

2015-1-1 Based on a literature review, lead nitrate works as an activator in the flotation of pyrite and sphalerite, with an activation process often described by at least two somewhat conflicting mechanisms. Finkelstein (1997) suggested that lead activation of sphalerite occurred through the exchange of Pb(II) with Zn(II), similar to Cu activation of ...
