Ore dressing test mainly includes preparation before test, test process and test result.
Ore dressing test is an important technical basis for the construction and production of ore dressing plant.By determining the properties of raw ore, we could master the properties and types of ore and determine the recoverable valuable elements. According to the test results, the beneficiation process is formulated to ensure the ore recovery rate and provide technical support for design and production.
The 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.
Special and innovative test schemes are customized based on different ore properties. Up to 29 schemes have been designed for gold mine processing.
The clients should provide about 50kg representative samples, some special samples about 200~1000kg. The simple test needs 30 working days, and the detailed test about half a year.
Sign the test contract with clients before the mineral dressing test, and make sure dressing process to test
Chemical Lab of Mineral Dressing Research Institute analyzes the material components (ore structure, mineral and types of ore) and chemical properties (elements, the particle size screening, density, ore relative grindability) of crude ore, and gets some data for the subsequent beneficiation test.
After the working of Chemical Lab, Mineral Dressing Research Room takes the mineral beneficiation test which tests the optimum conditions of dressing process. Testers take the exploratory testing at first relying on rich experience, and then the detailed testing including grinding fitness, reagent dosage, open and closed circuit test, etc. After obtaining the final products，testers should analyze them to get the recovery rate, and then take sedimentation test of concentrate and tailings as references of equipment selection.
