Studied the coordination chemical reaction of Fe、Co、Ni、Cu、Mg、Ca、Al with TC,OTC,CTC and the ternary association of Co-OTC、Ni-CTC with DAN,we found that the formation of new compounds improved significantly the hydrophilic properties of TCs,the TCs are transformed into hydrophobe from hydrophilic matter.

2研究了Fe、Co、Ni、Cu、Mg、Ca、Al与TC、OTC、CTC之间的配位化学反应和Co-OTC、Ni-CTC与DAN之间的三元缔合作用，发现新化合物的形成显著改善了TC、OTC、CTC的亲水性能，使其由亲水物质转变为疏水物质，有利于提高亲水有机溶剂气浮浮选体系对水样中痕量四环素类抗生素的测定灵敏度和分离/富集效率。

In the aqueous solution, Cu precipitates with ammonium thiocyanate and tetradecyl benzyl dimethylammonium chloride .

研究发现，在水溶液中Cu与硫氰酸铵、氯化十四烷基二甲基苄基铵形成不溶于水的三元缔合物，在少量氯化钠存在下此三元缔合物沉淀浮于水相上层并与水分成界面清晰的两相，分相过程中Cu被定量浮选。

The experiments include the flotaion of the different types of the Yinshan ores with different kinds of the flotation reagents and different flowsheets. The authors consider that for the flotaion of the lead and zinc ores, the necessity of using cyanides as depressants depends chiefly on the amounts of pyrite present and its ...

作者认为，对于那些黄铁矿含量少或黄铁矿易被抑制的铅锌矿石，采用优先浮选而不用氰化物作抑制剂是可行的，但对于那些含量大且可浮性好的黄铁矿的矿石，如果完全不用氰化物则要从药方与流程等来考虑。
