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.
First refractory gold ore is ground as finely as possible usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry which is mixed with surfactants to increase the golds hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.
Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment for the upgrading of low sulfide and refractory ores for further treatment. Flotation is considered to be the most costeffective method for concentrating gold. Flotation process maximizes the enrichment of gold

In Brazil the application of flotation for goldbearing ores started in the 1980s (Araujo and Peres 1995). There are three important Brazilian plants using flotation to process gold ores (Monte et al. 2002). At the São Bento plant gold and pyrite are floated into a bulk concentrate for further processing by pressure and bacterial leaching (the latter is currently on care and maintenance).
For vein gold ore with high arsenic and sulfur or high carbon argillaceous the gold sulfide concentrate can be obtained by the froth flotation and then the flotation concentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly sophisticated gold extraction method with low toxicity.
FLOTATION OF LOWSULPHIDECONTAINING GOLD ORES The beneficiation of this ore type usually involves a combination of gravity concentra tion cyanidation and flotation. For an ore with coarse gold gold is often recovered by gravity and flotation followed by cyanidation of the reground flotation
