摘要/Abstract

摘要：

电化学作为一门重要的自然学科在许多方面有着十分广泛的应用。湿法冶金是一门年青的冶金技术,其生产工艺机理的认识仍很不明确。在黄金湿法冶炼工艺流程的磨矿、选矿、预处理、浸出等单元中,电化学都有着广泛的应用和重大的指导意义。利用电化学理论来探讨黄金湿法冶炼中包括磨矿、浮选、预处理、氰化浸出、电解沉积、矿浆电解、贵金属回收、废水处理等生产工艺的机理,阐明了黄金湿法冶炼中各工艺流程的本质,有助于把黄金湿法冶炼工艺的研究推向深入。在解释机理和阐述本质的基础上,简要论述了电化学技术在黄金湿法冶炼中的应用。

关键词: 电化学, 湿法冶金, 应用, 机理

Abstract:

As an important nature subject, electrochemistry is widely used in many fields. Hydrometallurgy is a new metallurgical technique which has a not clear mechanism of production technology. Electrochemistry has a wide use and important significance in the process flows of gold hydrometallurgy including grinding, mineral processing, pretreatment, et al. The paper used electrochemical theory to discuss the mechanism in the production technology of gold hydrometallurgy including grinding, mineral processing, pretreatment, cyanide leaching, electrodeposition, slurry electrolysis, noble metal recovery, wastewater treatment, et al. and explained the principle of the process flows in gold hydrometallurgy. Gold hydrometallurgy could be studied profoundly for these. Basing on explaining mechanism and representing principle, the application of electrochemical technique in the hydrometallurgy was also briefly introduced.

Key words: electrochemistry, hydrometallurgy, application, mechanism
