INFLUENCE OF LEAD NITRATE ON CYANIDE LEACHING

2013-11-22  NaCN and 0.1 kg/Mg of lead nitrate. 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

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

Effect of Lead Nitrate on Gold Leach Kinetics

T3DB: Lead nitrate

Lead nitrate is a nitrate of lead produced synthetically by dissolving metallic lead or lead(II) oxide in nitric acid. It is an oxidizing agent and is used to make other lead compounds. It is also used as a heat stabiliser in nylon and polyesters, as a coating for photothermographic paper, and in rodenticides.

Lead processing Chemical compounds Britannica

2020-12-8  Lead processing Lead processing Chemical compounds: There are hundreds of organic and inorganic lead compounds, including oxides, carbonates, sulfates, chromates, silicates, and acetates. Most of these are manufactured from high-purity corroding lead. Litharge, or lead monoxide (PbO), is one of the most important of all metal compounds. Containing roughly 93 percent lead and 7 percent

Using lead nitrate in the zinc system can activate the zinc. It must be used in low dosages to prevent blinding off the surface of the zinc and preventing precipitation of precious metals. An excessive use of lead nitrate can form a lead hydroxide gel and blind the filters. Zinc must be added at a constant rate.

Third, when leaching after a pre-leach in which lead nitrate is added, the leach process proceeds far more quickly. Without any lead nitrate in the pre-leach, extraction is still continuing at 14 hours; with lead nitrate in the pre-leach at or above 50 g/t the cyanidation leach is more or less complete in 6 hours.
