摘要
利用电化学方法测定金在几种不同浓度和不同配比含硫试剂中的极化曲线,研究金在改性石硫合剂(ML)溶液中的溶解过程。结果表明,S2 O32 - 浓度在0 3～0 5mol/L时,溶金效果较好,加入SO32 - 有助于体系的稳定。NH3·H2 O、SO32 - 和S2 - x等有利于消除金表面的钝化。
The polarization curves of gold in sulfur bearing gold leaching solution with various compositions and concentrations are determined by electro-chemistry method, and the process of gold solving in MLSSS is investigated. It is indicated by the results that the leaching result is better in MLSSS at 0.3～0.5mol/L of the S 2O 3 2- content, and the addition of NH 3·H 2O, SO 3 2- and S x 2- is favorite to the deactivation elimination of the gold surface so the gold leaching result is improved.
