Copper silver ore refining process

Aug 02, 2021

Mar 27, 2020 Silver is found embedded in several different minerals, namely copper, zinc and lead, and the refining process varies depending on the source. Silver derived from copper and its derivatives, including copper sulfide, requires different handling and refining techniques than silver minerals taken from zinc deposits and lead sources. These metals have different

This mixture was spread in a one to two foot layer in an outdoor patio. After weeks of mixing and sun exposure, the native silver in the ore would bind with the mercury to form an amalgam. After that, pure silver could be extracted
