Research And Application Process On Multi Impurities K-feldspar

There are abundant feldspar mineral resources in Qingyuan and Tieling County Liaoning Province, However, the category of ores are complex, variety and high levels of impurities. In this thesis, take those ores as the research object. The purpose is to explore an effective and reasonable separation process, develop and utilize this part of mineral resources and provide practical ways.Mineralogical studies indicate that the main impurities in the ore are biotite, phlogopite, tourmaline, iron impurities. Determine the main route for flotation impurity, removal drop silicon, potassium mention under neutral conditions, Feldspar sorting the best under the grind size-0.074mm accounted for 50% to 60%.?8 cm cyclone-0.045mm fine mud removal. Through a single mineral impurities flotation tests, Screened paraffin oxide soap, xanthate, hydroxamic acids and oils sodium impurity better flotation reagents. Flotation reagents that have better impurity effect such as paraffin oxide soap, xanthate, hydroxamic acids and sodium oleate.Synthesis 4 kinds of amino esters cationic collector of N-dodecyl-?-alanine methyl ester, N-octyl-?-alanine methyl ester, N-dodecyl-?-amino-propionic acid methyl ester and N-methyl-oct-alkyl-?-amino-methyl-propionic acid methyl ester. Compared with other reagents, increase the carbon chain and branched groups, enhance the ability of quartz collectors mine.Establish SPSS model and simulate, and predict the unknown mineral optimal reagent system at the desired objectives. Research is supported by experimental procedure for different types of ore, which depending on the preparation of a flotation reagent flow structure for industrial production, and get good result by field trial.
