Inquartation and Parting Refining Process Ganoksin

Inquartation and PartingPirotechnia Aure8 Refining EquipmentRefining TrialThe technique mirrors part of the Fire Assay process used in the analysis (assay) of gold.Inquartation involves initially diluting the gold in the refinable material to about 25% (literally ‘quartering’ the gold) by melting with the appropriate addition of copper or silver, granulating the melt so as to generate a high surface area and then treating with nitric acid. The acid will dissolve the silver and base metals, leaving behind the gold. The aci在ganoksin上查看更多信息

Gold Inquartation Process Mineral ProcessingMetallurgy

The bead of silver and gold obtained by cupellation is squeezed between pliers, or flattened by a hammer on a clean anvil, to loosen the bone ash adhering to its lower surface, and is then cleaned by a brush of wires or stiff bristles. It is then weighed, the silver removed by solution in nitric acid, and the weight of the residual gold taken, when the difference between the two weighings

Processing, smelting and refining gold World Gold Council

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it

Silver processing Britannica

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
