  Thermodynamic calculations for the volatilization of arsenic and lead from molten copper at high oxygen level were performed using available thermodynamic data. An experimental setup was built in order to validate the predictions. Three experimental tests confirmed both the moderate volatility for Pb species (Pb+PbO) and the extremely low vapor pressure of As-O species, even at high Cited by: 1. a. A term for metallic lead in the lead industry to distinguish it from lead compounds with color designations, such as white lead, orange lead, and red lead. See also: lead. b. A synonym of galena, esp. a compact variety with a bluish-gray color. Syn: galena; blue lead ore. c.

The Bureau of Mines investigated a hydrometallurgical procedure to recover gold, silver, and byproduct lead from a complex lead-zinc sulfide ore. A ferric chloride (fecl3) preleach, at 40 deg c in 6 h, extracted about 50 pct of the zinc and formed insoluble silver and lead chlorides. LEAD, a metallic chemical element; its symbol is Pb (from the Lat. plumbum), and atomic weight (o=16).This metal was known to the ancients, and is mentioned in the Old Testament. The Romans used it largely, as it is still used, for the making of water pipes, and soldered these with an alloy of lead and tin.

A study of the dissolution of lead from powdered galena ore using acidified hypochlorous acid in excess chloride has been investigated. The effect of acid concentrations ranging from %, in temperatures between °C, speed of agitation in the range of rpm and particle size of.

Finally, volatilization of lead was evaluated in terms of chloride equivalent ratio of RCl (molar ratio of chloride to lead), and almost % of lead was found to be volatilized at RCl=27 in the case of CaCl2 addition to the simulated slag.

In this research, lead was separated from the glass matrix by a chloride volatilization process. Melting of the funnel glass together with CaCl 2 resulted in the volatilization of 80 % of lead at 1, C.

Preliminary experiments were carried out to confirm the influence of chloride on the lead stripping voltammetric oxidation peak.

Data were obtained by square wave voltammetry, as described in the experimental section, using a gold microelectrode in solutions containing % (m/v) HNO 3 and μmol L −1 Pb 2+ in the presence of different chloride concentrations (range of 0–50 mmol L −1).Cited by: 5.
