Cuppelation Furnace

The objective of the process is oxidizing the base metals from the noble metals such as gold and silver, to provide gold remain apart in order to specify the gold amount in metallic alloy materials and to determine the effect of the parameters such as processing temperature, amount of lead and experiment period on the analysis.

Cupellation (fire assay) is a quantitative analysis technique that is used for determining the amount of precious metals such as gold and silver in ore, concentrate or any other alloy. This process is based on the principle that precious metals do not oxidize or react chemically in high temperatures. By the way since the past, there has been some analysis methods for gold and silver. Some of them can be examined as touchstone, density and parting methods. In spite of lots of methods, the most reliable way is the cupellation process. (That has %0.02 accuracy.)
