河北铜矿矿石产于铜铁共生的接触交代矿床。含铜矿石按其可选性大致可分为两类:第一类为滑石、阳起石、透辉石、磁铁矿含铜矿石。金属矿物以黄铜矿、磁铁矿为主。嵌布粒度较粗,易于选别,称为易选矿石。第二类为蛇纹石、磁铁矿含铜矿石,金属矿物嵌布粒度较细,可选性差,称为难选矿石。生产实践证明,当入选矿石中难选矿石比例增加时,铜的浮选回收率随之下降。已查明,主要是墨铜矿及其与蛇纹石的连生
Hebei copper ore produced in copper and iron symbiotic contact with the deposit. Copper ore can be divided into two categories according to its optional nature: The first category is talc, actinolite, diopside, magnetite copper ore. Metallic minerals to chalcopyrite, magnetite-based. Embedded coarse grain size, easy sorting, known as easy to choose ore. The second category is serpentine, magnetite copper ore, metal minerals embedded fine grain size, poor selectivity, known as refractory ore. Production practice shows that when the proportion of refractory ore in the selected ore increases, the flotation recovery of copper decreases. It has been ascertained that it is mainly associated with the Mexican copper ore and its associated with serpentine
