本文基于对国内外几种载金活性炭解吸方法的分析,提出了研究解吸工艺的方向。通过对解吸机理的探讨,解吸剂和洗脱剂的选择,金银在解吸过程中的行为的研究,最终提出了一个无氰解吸新工艺。该试验已进行了全流程试验和逐级放大试验,都取得较满意的技术经济指标。本文重点阐述了解吸机理及其工艺。 Based on the analysis of several gold-supported activated carbon desorption methods at home and abroad, this paper proposed the direction of desorption process. Through the study of desorption mechanism, the choice of desorbent and eluent, the behavior of gold and silver during desorption, a new technology of non-cyanide desorption was finally proposed. The test has been carried out the whole process of test and step by step amplification test, have achieved more satisfactory technical and economic indicators. This article focuses on the desorption mechanism and its process.
