extraction of silver from ore

Mindat Mineralogy Messageboard

Aug 13, 2008· The cupellation process was used to assay silver as well as extract it Smelt the lead/silver ore Continue to heat with zinc (at about 10 of lead to 1 of scrap zinc) Skim off the zinc (if you let the whole lot cool together, you may be able to liberate the zinc using a hammer

The present is to discuss some of the current silver-treatment plants and also reviews briefly some of the older practices in important silver-mining areas since closed down The greater part of the world’s production of silver is derived from the refining of the base metals, particularly lead ores, and complex ores of lead, copper, antimony, and zinc.

Milling Technology in the Nineteenth Century

This was particularly useful for silver ore, often in the form of silver chloride, which required both salt and heat to alter the material before adding mercury for amalgamation and extraction Early Comstock miners constructed arrastras in 1859, but these proved generally inadequate for the extensive Comstock ore.
