摘　　要：为查明某贫硫化物碳酸盐型微细粒难处理金矿石工艺特性,对其进行了工艺矿物学研究,包括矿石矿物组成、主要矿物嵌布特征、嵌布粒度、金矿物工艺特征等。结果表明:矿石平均金品位15.17 g/t、硫0.65%、有机碳0.47%,有机碳吸附金占40.10%,金为唯一有价元素;矿石中有机碳含量高,而硫化物含量低,金矿物粒度微细并与脉石关系密切,脉石矿物泥化严重等均会影响金的回收。研究结果对该类型矿石的开发具有一定的指导意义。To find out the process mineralogy of one carbonate micro-fine refractory gold ore with low sulfide content,the paper carried out process mineralogy study on it,including mineral composition,embedding characteristics,embedding grain size,mineralogical characteristics of gold minerals. The results show that the average gold grade is15. 17 g / t,sulfur grade 0. 65 % and organic carbon grade 0. 47 %,40. 10 % gold is adsorbed by organic carbon,and gold is the only valuable element; the organic carbon content is high in the ore,but the sulfur content is low; severe argillization of gangue minerals and the fact that the grain size of gold minerals is micro-fine and closely related with gangues will both affect gold recovery. The results have certain guiding significance for the exploitation of the same type ores.
