·The Tavener process of melting the gold precipitate in a reverberatory furnace with litharge thus forming a lead bullion which was afterward cupelled in the usual way He deals with the zinc shorts by the same method but recommends that the two products be partially dried and separately fluxed For the precipitate he uses the following mixtures
Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product [1] It is a form of extractive metallurgy that is used to obtain many metals such as iron copper silver tin lead and uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal
·These smelting processes could be divided into two kinds namely indirect smelting and direct smelting In the indirect smelting process the calcine of refractory gold ores are added in the copper or lead smelting processes during which gold can be enriched into copper matte or crude lead Then gold is extracted from the anode slimes
