摘　　要：采用经典的金的化学物相分析方法,对青海省五龙沟金矿矿石中金的物相进行了分析;以活性炭吸附—沉淀灰化、溶解后,通过选用最佳仪器工作条件,采用Z-2000原子吸收光谱法直接测定各物相中的金。实验结果表明,青海省五龙沟金矿矿石中的金主要是以铅锌铜硫化矿包裹金的赋存形式存在。该实验结果有助于阐明青海省五龙沟金矿矿床成因,为地质勘探、矿床评价和选冶工艺确定,以及有效地综合利用金矿资源提供依据。Commonly used phase analysis method of gold is employed to carry out the phase analysis of gold in gold ores from Wulonggou Gold Mine in Qinghai. With activated carbon adsorbing gold after precipitation ashing and dissolution, and in optimal equipment parameters, the Z -2000 atomic absorption spectrometry was used to determine gold in each phase directly. The experiment results show that the gold in Wulonggou Gold Deposit mainly takes the form of inclusions by lead, zinc and copper sulfide minerals. The conclusion is helpful in elucidating the genesis of Wulonggou Gold Deposit, and provides grounds for exploration, deposit evaluation and the determination of metallurgi- cal processes, and efficient comprehensive utilization of gold resources.
