Abstract


Thesis topics from the 973 sub-topics \Cation collectors involved include : straight-chain aliphatic amines , quaternary ammonium Gemini cationic collector , and a new silicone cationic collector agent . Anionic collector involved mainly of oleic acid, hydroxamic acid TBBA, alkyl dicarboxylic acids the DSA and alkyl aryl . The main contents and results are as follows : ( 1 ) through the single mineral flotation experiment , the type of ionic groups , the length of the hydrocarbon structural factors on the ability of the pharmaceutical collectors . The results show that : the straight-chain aliphatic amines and new organic silicon collector flotation of smithsonite better than conventional quaternary ammonium Gemini cationic collector . The aliphatic amines collector strongest dodecylamine collecting capacity . New silicone cationic collector TAS101 the the collecting capacity smithsonite dodecylamine quite selectively better . ( 2 ) through the single mineral flotation experiment , examine of of traditional anionic collector oleic new anionic collector DSA and TBBA smithsonite collector performance . Significantly better than DSA in a broad pH range of smithsonite flotation effect of oleic acid and TBBA collecting capacity order : DSA gt ; oleic gt ; TBBA . The ore grade of about 9.70% zinc oxide ore flotation experiments , get a good open-circuit indicators concentrate grade of 36.28% , the recovery rate was 55.45% . (3) through the flotation solution chemical analysis , mineral Zeta- potential measurement and infrared spectroscopy , a means to explore the mechanism of silicone the cationic collector TAS101 and oleic acid on smithsonite . The results indicate that the role of the silicone the cationic collector TAS101 and smithsonite electrostatic adsorption and the amine salt chemical adsorption , oleic smithsonite role chemisorption .
