摘要/Abstract

摘要：

介绍了难浸金精粉箱式静态生物氧化的基本方法流程,试验样品采用该方法处理187d 后,金的浸出率由37.04 %提高到93.01 % ,基本达到槽式搅拌氧化93. 68 %的水平。经济分析认为小型金矿山采用箱式静态生物氧化处理难浸金精粉,投资、成本分别为槽式氧化的1P3 和1P2 ,具有很强的实用性。

Abstract:

The basic principles of the bio-oxidation of refractory gold-bearing concent rate in oxidation-box in static state are int roduced. Through 187 days’bio-oxidation , the test-samples, the gold leaching rate came f rom 37.04 %(before bio-oxidation) to 93.01 %(after bio-oxidation),and this result got a same level as the tank bio-oxidation (93.68 %). The economic analysis shows that a small scale gold mine take this technics to process the ref ratory gold2bearing concent rate,the cost and capital will only be 1P3 and 1P2 respectively of a same scale tank bio2oxidation plant,and the favorable practicability are forecasted to this technics.

Key words: refratory gold2bearing concent rate, oxidation2box, static state, bio-oxidation
