Effect of lead nitrate on cyanidation of gold ores ...

2000-10-1  In gold production practice, abundant sulphides sometimes exist in the mineral pulp. When lead nitrate is added to the pulp, lead sulphide is formed. This does not mean that the lead salt looses its efficacy, but it can continue to affect the cyanidation process. The curve in Figure 3 has a comparable corrosion potential and a similar corrosion ...

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 ...

A further increase of lead nitrate to 0.3 kg/Mg resulted in the decrease of Au and Ag leach recovery by comparing with the test of 0.2 kg/Mg lead nitrate, indicating the formation of Pb(OH) 2 passive layer on gold. Besides, NaCN consumption increased from 0.24 kg/Mg without lead nitrate to 0.27
