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.
This configuration is suitable when the sample load must fit a 278 x 388 x 595 MM chamber with usable chamber volume of 64.2 litre, approximate power load of 15.5 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.

Trutherm manufactures 1100 Degree Celsius (°C) Gold Refining Furnace 278 x 388 x 595 MM Chamber for buyers who search by exact machine type, chamber size and 1100°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.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
