gold processing

This process involves melting a gold-bearing sample in a clay crucible with a mixture of fluxes (such as silica and borax), lead oxide (called litharge), and a reducing agent (frequently ). The fluxes lower the melting point of the oxidic materials, allowing them to fuse, and the molten litharge is reduced by the to extremely fine
