Study on Gold Leaching from Waste Printed Circuit Board by Iodide Process 碘化法从废弃印刷线路板中提取金的研究
Thermodynamic Analysis for Gold Leaching with Iodide 碘化物浸金过程的热力学分析
It showed from experiments that the best approach to the treatment of fine grained disseminated gold ore was hot press oxidation of flotation concentrate of pyrite followed by cyanide leaching. formed is reacted with excess of iodide in an acidic medium to give free iodine ( I?) 试验结果表明:对含金黄铁矿精矿进行压热氧化&氰化浸出,是处理该微细粒浸染型金矿石较有效的方法。
Research of Cementing Gold out from Iodide Leaching Liquor and Recovering of Iodide Liquor 碘化浸金时从浸出液中提金及碘再生方法研究
The thermodynamic criterion and the equilibrium constant criterion of the gold leaching with iodide were proposed. The leaching system of gold with iodine-iodide was thermodynamically analyzed. 通过推导碘化物浸金过程的热力学判据,提出碘化物浸金的平衡常数判据,对碘-碘化物浸金体系进行了热力学分析。
