Solved Lead can displace silver from solution, and silver
Science. Chemistry. Chemistry questions and answers. Lead can displace silver from solution, and silver occurs in trace amounts in some ores of lead: Pb (s) + 2 Ag+ (aq) → Pb2+ (aq) + 2 Ag (s) As a consequence, silver is a valuable byproduct in the industrial extraction of lead from its ores. Calculate K and AG at 298.15 K for this reaction.
Common Silver Extraction Methods
The common gold-silver ore extraction process has the following types: 1. Flotation + Flotation concentrate cyanidation. The sulfide ore containing gold, silver and quartz veins is subjected to flotation process to obtain a small amount of concentrate, which is then sent to cyanidation process.
Silver
Although silver was a principal product at several mines, silver was primarily obtained as a byproduct from lead-zinc mines, copper mines, and gold mines, in descending order of production. The polymetallic ore deposits from which silver was recovered account for more than two-thirds of U.S. and world resources of silver.
