Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the ...

This equipment is for the primary concentration of classified alluvial ore and milled hard-rock ore. It is known for its high-volume, zero-loss fine gold recovery. Our machine is adaptable to any mine operations, replacing sluices and jigs. It runs on turbid water, which is perfect for recycle and settling ponds. Two Models:
Gold and silver are obtained from a variety of ores. Most people think of nuggets and such, but the truth is that very little comes from nuggets - nearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even microscopic particles.
gold ore cupellation equipment html Optimisation of fire assay analyticalOptimisation of In practice, cupellation is the most efficient method in terms of cost, accuracy, precision and robustness when the composition of the alloy is not too complex.
Cupellation is a refining process to removing all non-precious metals to detect exactly precious metal, like gold and silver. The ores or alloyed metals are treated under very high temperatures and have controlled operations. System includes all needs: Polypropylene Hood and Working Chamber; All Glass Equipment for Tests; Cupellation Furnace
The proper temperature for cupellation of gold ores is the same as for silver ores. The lowest temperature at which good soft lead uncovers is about 675°—that is, a dull red heat—and a good temperature for the air in the muffle is 700°, which need not be reduced throughout the operation. Litharge freezes at about 640°.
