A classifier equipment with overflow end spiral completely submerged below the liquid surface.
Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
Cupellation separation of gold or silver from impurities by melting the impure metal in a cupel (a flat porous dish made of a refractory or hightemperatureresistant material) and then directing a blast of hot air on it in a special furnace. The impurities including lead copper tin and other unwanted metals are oxidized and partly vaporized and partly absorbed into the pores of the cupel.
Boiling with concentrated sulfuric acid to separate silver and gold is called affination. Both these processes are used on a commercial scale for separating silver and gold. History. Silver was discovered after gold and copper about 4000 bce when it was used in jewelry and as a medium of exchange
My answer is to getting the gold free of copper and it works for any alloy. 1. Raise the surface area/volume. Beat it until it is as thin as possible or crush it and do your best to make dust/tiny fragments. 2. Put the whole of the sample into a...

Gold occurs principally as a native metal usually alloyed to a greater or lesser extent with silver (as electrum) or sometimes with mercury (as an amalgam).Native gold can occur as sizeable nuggets as fine grains or flakes in alluvial deposits or as grains or microscopic particles (known as color) embedded in rock minerals.. Ores in which gold occurs in chemical composition with other
