锡矿主要伴生硫化矿的基本性质及浮选行为

Proporty and Floatation Behaviour of the Main Associated Sulphides in the Tin Ores

通过对大厂的脆硫锑铅矿、铁闪锌矿、黄铁矿及主要脉石纯矿物的基本性质测定和浮选ＰＨ值、抑制剂、捕收剂等的研究，得出脆硫锑铅矿－铁闪锌矿与黄铁矿的最佳分离条件：矿浆ｐＨ＝１０．６时或ＮａＣＮ浓度４．４５×１Ｏ￣（－２）毫克分子／升时，混合捕收剂为丁基钠黄药：乙硫氮＝１：１。

AbstractThe proporties of the jarnesonite.mar-matite pyrite and main gangue minerals from Dachang mine were investigated. Thestudy on PH value.depressor.aid collectorsof the flotation for these sulfides shows thebest conditions of separating the jamesoniteand marmatit from pyrite are:PH=10.6、NaCN conC.4.45×10￣(-2)mmol/l、[Bx￣-]:[SN-9]=1:1.
