Minetal Processing Research Of Andalute Ores From XIXIA Mine In HENAN Province

The andalute is the kyanite race high aluminum minerals, has underthe high temperature stable volume, the expansion rate low, anti-chemistry corrosiveness strong, the mechanical strength and resistsheat the impact ability strongly and so on a series of fine characteristics, therefore, in domain application and so on metallurgy profession, fire-proof material, light quality high strength alloy,metal textile fiber, spaceship is wide spread.According to the incomplete statistics, our country has verified the andalute ore reserves approximately is 560 million tons, the ore according to the average personal status 12% idea, then the andalute mineral reserves approximately is 67 million tons. The andalute ore deposit mainly distributes Henan Xixia, theXinjiang Korla and Baicheng, Liaoning places such as Shiuyan -Fengcheng, Shaanxi Mei Xian." Henan Xixia andalute Ore Dressing Craft Research"belongs to "the Henan Province 2004 year prospectings power, the mining power working cost and the cost minerals investigation(scientific research) the project", the project work goal duty is: Henan Xixia andalute ore is a raw material, after the dressing processing craft research, the generating up scale large grain andalute aggregate and the thin size fire-proof material, the reasonable development uses our province Xixia County andalute highquality mineral resource.This experimental study work mainly divides into three parts: First part: Craft mineralogy research. Through the application opticalglass analysis, the thin slice analysis, the heavy mine analysis, the phase analysis, the X- beam diffraction analysis, the infrared wavescanning analysis, the electricity mirror power spectrum analysis and so on the many kinds of methods, verified the ore material composition, the structure, the foreign inclusion, the mineral tax have saved the condition, mount the characteristic and influence mineral depuration each kind of factor.Second part: Phase analysis method research. In view of the Henan Xixia andalute Ore, through in the ignition temperature, the ignition time, dissolves aspect the and so on ore temperature, solventtype, disturbance mineral separation, method accuracy and accuracy experimental study, has discovered this mining area andalute phaseanalysis correction factor, thus studied the suitable phase analysis method.Third part: Dressing craft research. The experiment separately uses"the selectivity brokenly, the friction throws the tail, the heavymedium dressing" and so on, applies the magnetism heavily,floats and the union dressing craft processing different sizes andalute ore, according to the "first throws the tail, the partition concentrates" principle, finally had determined reasonable dressing technical process, namely"selective broken - friction -heavy medium - strong magnetic separation - flotation process" the union flow, separately obtains "-3.0+1.0mm", "-1.0+0.5mm" and "-0.5mm"three ranks andalute concentrates. Its classification target following table -1 shows:...
