How silver is made - material, making, history, used ,A Guide to Mercury Applications in Metalurgy - The Balance

Silver was first obtained in sixteenth-century Mexico by a method called the patio process It involved mixing silver ore, salt, copper sulphide, and water The resultant silver chloride was then picked up by adding mercury This inefficient method was superseded by the von Patera process In this process, ore was heated with rock salt .By passing the mercury vapor through a water-cooled condenser, the mercury, which has a high boiling point, is the first to condense into its liquid metal form and collected About 95% of the mercury content of cinnabar ore can be recovered using this process.

Mercury - California Geological SurveyMercury processing - Britannica

It was the main ore of mercury at many California mercury min It is characterized by its bright red color Mercury was recovered by heating the cinnabar and collecting and cooling the mercury vapors that were produced Mercury is present in the environment as a result of both natural processes and human activiti .Mercury deposits are small and irregular, occurring sometimes as disseminated deposits but usually as veinlets This precludes large-scale, highly mechanized mining methods The most common method of ore recovery is underground mining, with conventional drilling and blasting followed by scraping or mechanical loading into ore cars.
