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.
Discovered in 1886 it produced 25 percent of the worlds gold by 1899 and 40 percent by 1985. The discovery of the Witwatersrand deposit coincided with the discovery of the cyanidation process which made it possible to recover gold values that had escaped both gravity concentration and amalgamation.
The final stage of gold production refining involves removing impurities that remain after the smelting process. Refining companies receive doré bars as well as scrap gold and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal which separates the pure gold from other precious and less precious metals.

The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction. Thus the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination and the residue may then be treated by smelting to recover the balance. Generally scrap with a gold content of less than 0.1 percent unless readily recoverable by
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.

Gold parting is the separating of gold from silver. Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver gold and silver alloy is called electrum.
