Emphasizing on Sample Representativeness for Complex Tests of Multiple Mining Points

Generally, the ore properties of different ore occurrences are different, so the ore supply of many mines is completed by multiple ore occurrences. Based on different ore properties, Xinhai has formulated the representative sampling method.

Providing Accurate Tests for More Than 70 Kinds of Ores

Xinhai chemical laboratory has such a complete set of modern advanced equipment as crusher, fine grinder, roaster, dryer, spectrometer, atomic fluorescence spectrometer, atomic absorption spectrophotometer, infrared ore analyzer and detector, etc. The mineral processing research institute has a sample crushing room and can conduct rock ore identification, Bond grinding work index test, intelligent laser particle size detection and so on. Optimal mineral processing technology will be provided after various mineral processing tests including gravity concentration, magnetic separation, flotation, cyanide leaching and adsorption, bacterial oxidation, acid leaching and wet mineral processing, special mineral processing, dump leaching, tailings thickening and dry tailings stacking.

Conducting Mineral Processing Test with Innovative Thought

Special and innovative test schemes are customized based on different ore properties. Up to 29 schemes have been designed for gold mine processing.
