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.

The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes ores in which the valuable minerals are those of the base metals the precious metals being incidental constituents and ores in which the gold and silver are of primary importance the basemetal minerals if present being of little or no value. The first class
The gold concentrate yield is 6.81% the taste is 33.8g/t and the recovery rate is 88.19%. Therefore in order to improve the recovery rate of gold flotation it is necessary to conduct a beneficiation test to find the best grinding fineness the ratio of the capture agent the amount of the capture agent the amount of foaming agent and the flotation time.

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore even when a proportion of the gold is free. Gold does float readily however and the free gold can be selectively floated away
Laboratory flotation tests on a flotationplant tailing sample using NaHS and silver ions recovered 3045% of the unfloated gold and NaHS provided the best results. Application of this information at plant scale resulted in a 7% increase in gold recovery at the Los Pelambres Mine in Chile ( Chryssoulis 2001 ).
