(微)生物过程与贵金属工业

Microbfological process and precious metal industry

本文对(微)生物法提取、回收贵金属这一新方法从浸出剂、预处理、回收净化、动植物富集金等八个方面进行了系统地阐述。并探讨了菌类在动植物溶金、移金和富金中的初步机理。同时提请各界注意生物—植物—冶金之间的内在联系,渴望在边缘学科有所突破和发展。

This Paper covers systematically the eight aspects of the way of extraction or recovery of precious metals by biological processes.ie.lixiviant pretreat-ment recovering and cleaning,amimal/plant-concentrating gold,etc.In addition,the tentative mechnism of bacteria's approach to dissolve,transport and concentrate gold by animals and vegetables is diseussed. Moreover, every attention is required to pay on the internal relationship between organism and metallurgy.The authors expect some greater breakthrough and development to be made in this frontier.
