简介本讲座为碳浆法回收金提供了广阔的远景.所研究的专题包括历史、流程图和工艺的说明、与常规工艺相比较、理论、操作实践、以及将来的趋向.其中表达的观点根据技术参考文献及现场经验和作者本人的意见.历史实际上,活性碳能从溶液中吸附贵金属的特性,是莱扎斯基于1847年第一次发表的.这一报道当时引起人们相当大的兴趣.从1848年到1917年间发表的大约46篇技术论文可以证实这一点.首先在冶金系统使用木炭在氯化之后用来提取金.金先被
INTRODUCTION This lecture provides a broad perspective on the recovery of carbon slurry, covering topics such as history, flowcharts and processes, theoretical, operational practices, and future trends compared to conventional processes, where the views expressed are based on Technical references and field experience and the author’s own opinion History In fact, the ability of activated carbons to adsorb precious metals from solutions was first published by Lazarsky in 1847. This report was of considerable interest at the time This was corroborated by some 46 technical papers published between 1848 and 1917. First, charcoal was used in the metallurgical system to extract gold after chlorination
