辉钼矿与方铅矿的连生关系及其对选矿指标的影响

INTERLOCKING RELATION OF MOLYBDENITE AND GALENA AND ITS EFFECT ON SEPARATION TARGET

辉钼矿多呈板状、鳞片状、叶片状单晶及其集合体状,除了与非金属矿物共伴生外,常与金属硫化物黄铁矿、黄铜矿、方铅矿等共伴生,因此,在辉钼矿的选矿过程中,辉钼矿与其他共伴生矿物的嵌布特征是影响选矿指标的关键。辉钼矿与方铅矿多呈包含关系,用机械浮选,很难使得钼精矿中的杂质元素铅含量符合标准。

Molybdenite mainly occurs as plate -like, scalelike , lamellar single crystalline and aggregate shape. Be- sides non -metallic minerals , molybdenite associates with metal sulfides such as galena, pyrite, chalcopyrite and so on. Therefore, in the process of molybdenite flotation, the dissemination characteristic of molybdenite and other associated mineral is the key to affect mineral processing indexes. Molybdenite and galena are usually in inclusion relation, so it is difficult to guarantee that the lead content which is impurity element in molybdenum concentrate accords with the standard by mechanical flotation.
