本文略述了氧化铜矿石硫化浮选的基本原理,着重介绍了铜录山氧化铜矿石硫化浮选的实践经验及存在的问题. 一、氧化铜矿石的可浮性影响氧化铜矿石可浮性的因素较多,主要与铜矿物的种类、含泥量的大小、结合氧化铜的含量及有用矿物与脉石的嵌布特性有关. 在氧化铜矿物中,碳酸盐的铜矿物可浮性较好,如孔雀石,蓝铜矿.而硫酸盐矿物-水胆矾、硅酸盐-硅孔雀石、磷酸盐-假孔雀石、铜的氯化物-氯铜矿等可浮性都比较差.现将几种主要的氧化铜矿物的可浮性列入下表.
In this paper, the basic principle of sulfide flotation of copper oxide ore is briefly described, and the practical experience and existing problems of copper sulfide ore flotation are emphasized.First, the floatability of copper oxide ore affects the copper oxide ore Many factors of stone floatability, mainly associated with the type of copper minerals, the amount of clay content, combined with the content of copper oxide and useful minerals and embedded characteristics of gangue in copper oxide minerals, carbonate Of copper minerals have good floatability, such as malachite and azurite, whereas sulphate minerals - aquazeolite, silicate-chrysocolla, phosphate-malachite, copper chloride- Such as floatability are relatively poor now several main copper oxide flotability included in the table below.
