The chemistry of the Hispanic-American amalgamation process

Journal of the Chemical Society, Dalton Transactions, 1999
The chemistry of the Hispanic-American amalgamation or patio process for the extraction of silver has been studied through a laboratory model in which a suspension of silver sulfide in concentrated sodium chloride solution reacts with copper(II) chloride before being treated with mercury. Approximately 90% of the silver was extracted and separated as a
