南祁连党河南山地区地处南祁连重要成矿带,金铜矿化广布,该矿化与中酸性花岗岩类关系密切.为揭示区域成矿地质背景,查明大地构造的时空演化,并深入研究该地区金铜矿化的成矿规律与控矿因素,对区内主要花岗岩体及其金铜矿化进行了系统的地质地球化学研究.研究表明,区内花岗岩类岩体包括扎子沟岩体、鸡叫沟岩体及贾公台岩体.综合岩相学、岩石化学及微量稀土元素地球化学特征,区内3个岩体均形成于I型活动陆缘环境,为中南祁连造山带加里东期构造岩浆活动的产物.扎子沟岩体与该区金铜矿化不构成物源关系,但其岩浆期后热水溶液可造成火山岩系金、铜组分活化迁移,并在有利构造场所富集成矿,鸡叫沟岩体和贾公台岩体分别是黑刺沟金矿和贾公台金矿的控矿母岩.     

Untersuchung der Anwendungsmöglichkeiten von einigen komplexbildenden Ionenaustauschern zur Kupferabtrennung aus natürlichen Wässern und Abwässern

Application of Some Complexing Ion Exchangers for Copper Recovery from Natural Water and Wastewater The rational use of water resources is one of the urgent environmental control problems. These problems can be solved by the treatment of sewage. Removal of different non‐ferrous heavy metal ions from wastewater is of great importance. Besides, the selective complexing ion exchangers are of interest because of their good sorption properties. The present paper is devoted to the study of some complexing resins for copper recovery from natural water and sewage. The following carboxylic resins were studied: the cation exchangers KB‐2T, KB‐4 and the amphoteric ion exchangers ANKB 35, AMF‐2T, and AMF‐2S (manufacturer – “TOKEM” company, Kemerovo, Russia). The exchangers investigated differed from each other both by their functional groups and by their matrix physical structures. The copper recovery from CuCl₂‐, CuSO₄‐, and Cu(NO₃)₂‐solutions was studied in batch‐experiments (in presence of NaCl, Na₂SO₄, and NaNO₃). The initial copper concentration in the solutions was 0.0002...0.008 mol/L; pH values were 1.0...5.0. After equilibrium (24 h) the resins were separated from the solution. The copper concentration in the solutions after the sorption was determined by the photometrical method with pyridylazoresorcin (λ = 500 nm). On the basis of the experimental data distribution ratio, the separation factors, equilibrium constants, and stability constants of copper complexes in the exchanger phase were calculated. It was found out in this work that the amphoteric ion exchanger AMF‐2T of macroreticular structure is the most effective for the copper sorption from sewage.
