卡林型金矿通常具有品位低、规模大、埋藏浅等特点,矿石中多含有砷、硫、锑及有机碳等有害杂质,属难处理金矿资源,也是中国重点开发的金矿类型。简要介绍了其资源量及分布特点,同时分析了其难选难浸的主要原因;评述了卡林型金矿几种主要预处理技术的优缺点及适用性,主要包括焙烧法、浮选-焙烧法、生物氧化法、热压氧化法及其他预处理方法。

Carlin-type gold deposit,commonly possessing the qualities of low grade,large scale and shallow buri-al,belongs to the refractory gold ore resources,in most cases containing hazardous impurities like As,S,Sb and organic carbon.It also is one of the important gold types in our country.The reserves,distribution status and characteristics of the resources were briefly introduced in this paper.The refractory reasons of carlin-type gold deposits were analyzed.A few of pretreatment techniques of carlin-type gold deposits were reviewed in their advantages and disadvantages and applicability,including roasting process,flotation-roasting process,biological oxidation process,hot-pressure oxidation process and so on.
