通过硫化物矿物对银离子的吸附实验研究表明,在50℃时,硫化物矿物对溶液中银离子的等温饱和吸附量大小顺序是:方铅矿>黄铜矿>辉锑矿>闪锌矿;当温度超过70℃时,这个顺序变为:辉锑矿>方铅矿>黄铜矿>闪锌矿。这与天然多金属矿床中硫化物矿物银的含量顺序是一致的。实验证明,硫化物具有把溶液中的银富集到固体(矿物中)达106量级以上的能力。这些结果极好地解释了多金属矿床中银在普通硫化物中含量大小的顺序及锑和银在矿床和矿物上密切共生的关系。
The experimental study on the sorption of silver ions by sulphide minerals showed that the isothermal saturation adsorption capacity of sulphide minerals to silver ions in solution at 50 ℃ is: galena> chalcopyrite> stibnite> sphalerite ; When the temperature exceeds 70 ℃, the order becomes: stibnite> galena> chalcopyrite> sphalerite. This is consistent with the order of sulfide mineral silver in natural polymetallic deposits. Experiments have shown that sulfides have the ability to enrich silver in solution to solids (in minerals) by more than 106 orders of magnitude. These results provide excellent explanations of the order of silver content in common sulphides in polymetallic deposits and the close symbiosis of Sb and Ag on deposits and minerals.
