FIRE ASSAY CRUCIBLES / ASHES ASSAY CRUCIBLES

We supply high quality , multi-use Fire Assay Crucibles, Ashes Assay Crucibles and Scoriiers for the analysis of Precious Metals (Gold, Silver, and Platinum Group Metals) using the Fire Assay / Cupellation method (“Sgma”). Platinum group metals include: ruthenium, rhodium, palladium, osmium, iridium, and platinum.

The process to analyse the above metals is the fire assay method. It consists of melting a sample along with other assay fluxes under high temperature, and reducing conditions. It is possible to Fire Assay the following materials:

● Ores coming from Gold mines, and Geological Labs. This ores consists of samples of drill cores, trenches or grabbing.

● Mineral concentrates and electrolytic slimes. Copper smelters are the most common processors of mineral concentrates.

● Scraps & Residues (ashes) from sweeps, filings, lemel or catalysts . Precious metal refineries recycle these materals.

PROPERTIES OF OUR FIRE ASSAY CRUCIBLES AND ASHES ASSAY CRUCIBLES

Our universal fire assay crucibles and ashes assay crucibles material of construction is fireclay mixed with other refractory materials. They withstand temperatures up to 1300`C.

This composition and their design give them an excellent resistance against flux attack, erosion, cracking and thermal shock. They can therefore work under harsh conditions, and have a longer life. Furthermore, they have a high resistance to thermal shock, and produce a faster fusion, and constant melting speed .

Another important feature of our fire assay crucibles, is that they are very stable because of their wide base. This is particularly relevant for furnaces that have an irregular ground due to flux attack and erosion.

Last but not least, their dense body also minimizes absorption losses.

FIRE ASSAY CRUCIBLES

Our Universal Fire Assay Crucibles most common use is to melt auriferous ores and concentrates.

Their design allows nesting, and we therefore obtain an optimal space utilization in the warehouse, and minimal transport costs to any location.

The capacity of these crucibles ranges from 1 to 2-¼ assay-tons and suit most Assayers’ jobs. :
