摘要
评述了硫化镍试金预富集贵金属 ,然后采用中子活化法、感耦等离子体质谱法、原子吸收光谱法以及感耦等离子体原子发射光谱法测定痕量、超痕量贵金属的现状 ;并对硫化镍试金富集贵金属的机理进行了探讨 ,晶体结构及贵金属硫化物和硅酸盐渣相化合物的热力学数据表明 ,在硫化镍相和渣相分离时 ,贵金属趋向于进入硫化镍相。引用文献5
This article reviewed current determining situation of trace,ultra trace precious metals.Precious metals are collected at first by nickel sulfide fire assay,then determined by neutron activation analysis,inductively coupled plasma-mass spectrometry,atomic absorption spectrometry,atomic emission spectrometry methods.The mechanisms for nickel sulfide fire assay collecting precious metals were discussed.According to crystal structure and thermodynamics data of precious metals sulfide and compounds in silicate phase,precious metals tend to be in nickel sulfide phase when nickel sulfide phase is separated from silicate phase.54 articles were referred.
