Fire Assay Fusion Furnace

The fire assay process is a fundamental and time-honored technique in the mining and metallurgical industries, used to accurately determine the concentration of precious metals such as gold, silver, and platinum group elements (PGEs) in various ore samples and metallurgical products.

DECENT Fire Assay Fusion Furnace is essential for laboratories conducting precious metal analysis. It melts crushed ore samples mixed with fluxes in refractory clay crucibles. The industrial-sized furnaces have spacious chambers that can hold multiple crucibles simultaneously, enhancing laboratory efficiency and reducing manual operations. DECENT fusion furnaces are equipped with an advanced automatic temperature control system that ensures uniform and stable high temperatures, reaching up to 1200°C. This precise thermal management is crucial for the reliability of the fire assay process and the accuracy of analytical results.
