This furnace is part of a system used to purify gold, separating it from other metals and impurities. Operating at temperatures around 1100°C, it facilitates chemical reactions like chlorination or the Miller process. The working principle involves melting the impure gold with specific fluxes or bubbling chlorine gas through the melt, causing impurities to form a slag or fume off. Its purpose is to produce high-purity (99.9%+) gold from scrap, ore, or doré. It is central to precious metal refineries and recycling operations.
