铂族元素钌、铑、钯、锇、铱、铂等属于周期系的第八族稀有元素。其化学与物理性质彼此相似,故在自然界中常共生,并与砷、硫、锑等形成化合物。它们的原生矿物主要富集在与超基性岩、基性岩有关的铜镍矿床、铬铁矿床和砂矿内。有的则以单矿物存在,或以类质同象进入硫化镍和硫化铜的晶格中。目前,国内外在地质找矿方面,铂族元素的分析方法有火法试金、离子交换、中子活化、色层分离、原子吸收光谱、化学光谱及试金光谱等方法,分别测定或同时测定铂族六个元素。由于矿石中含铂族元素甚微,故用光谱
The platinum group elements ruthenium, rhodium, palladium, osmium, iridium, platinum and other periodic elements belong to the eighth group. Its chemical and physical properties similar to each other, it is often symbiotic in nature, and with arsenic, sulfur, antimony and other compounds. Their primary minerals are mainly concentrated in Cu-Ni deposits, chromite deposits and sands associated with ultrabasic rocks and basic rocks. Others exist as single minerals, or in a similar way, into the lattice of nickel sulphide and copper sulphide. At present, domestic and international geological prospecting, the analysis methods of platinum group elements include fire test gold, ion exchange, neutron activation, chromatography, atomic absorption spectroscopy, chemical spectroscopy and gold assay, respectively, or simultaneously Determination of six elements platinum group. As the ore contains little platinum group elements, so the spectrum
