对于含有多种金属矿物以及银呈不同形式存在的矿石,由于物理和物理-化学性质上的差异,使含银矿石的选矿问题变得复杂化。 通常,浮选这种矿石是按回收主要金属(有色金属)确定条件。显然,这样选择流程不能保证很好地回收银。 研究结果表明: (1) 矿石氧化较深,2/3的铅矿物呈氧化物形式:铅矾(34％),白铅矿(6.8％),铅铁矾(25.2％)。但是锌矿物氧化程度较低,矿石中90％的锌是闪锌矿;
For ores that contain many metallic minerals and different forms of silver, the beneficiation of silver-bearing ores is compounded by the physical and physical-chemical differences. Generally, flotation of such ores is based on the recovery of the major metals (non-ferrous metals). Obviously, such a selection process can not guarantee good recycling of silver. The results show that: (1) Ore is deeply oxidized. Two thirds of the lead minerals are in the form of oxides: lead alum (34%), white lead ore (6.8%) and lead iron alum (25.2%). However, the degree of oxidation of zinc minerals is low, 90% of the zinc in the ore is sphalerite;
