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.

Trutherm manufactures 1200 Degree Celsius (1200°C) Gold Refining Furnace 840 × 890 × 840 MM Chamber for buyers who search by exact machine type, chamber size and 1200°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
This configuration is suitable when the sample load must fit a 840 × 890 × 840 MM chamber with usable chamber volume of 628 litre, approximate power load of 39.2 kW, rectangular - tall chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
