摘要
为了更有效地的回收矿石中的有价成分,采用光谱分析、多元素化学分析、岩矿鉴定及物相分析等方法对栗木钽铌钨锡矿矿石的工艺矿物学特征进行了系统研究.结果表明:矿石的矿物主要由石英、钾长石、钠长石及云母组成,四者的含量合计约占矿石的95%;矿石的有价金属元素有钽、铌、钨、锡、铷,分别存在于钽铌(铁)锰矿、黑钨矿、白钨矿、锡石、黝锡矿、云母与钾长石中.根据工艺矿物学研究结果,矿石中可以综合回收的金属矿物包括钽、铌、钨、锡矿物,非金属矿物包括石英、云母以及长石;影响目的矿物回收的工艺矿物学因素主要包括矿石的结构、后期蚀变、矿物自身的脆性以及表面特性的相似性等.
To recovery valuable minerals in the ore, the process mineralogical characteristics of tantalum- niobium-tungsten-tin ore in Limu mine were studied by spectral analysis, multiple-element chemical analysis, mineral examination, chemical phase analysis and other testing methods. The results indicate that the main components are quartz, potash feldspar, sodium feldspar and mica, which account for about 95% of total amount. The valuable metals in the ore are tantalum, niobium, tungsten, tin and rubidium, which are contained in tantalum niobium (iron) ore, wolframite, scheelite, cassiterite, stannite, mica and potassium feldspar separately. Research results of process mineralogy show that the metallic minerals containing tantalum, niobium, tungsten, tin and nonmetallic minerals such as quartz, mica and feldspar are comprehensively recoverable minerals in the ore; the main process mineralogical factors impacting the recovery of objective minerals include ore texture, paulopost alteration, brittleness of the mineral itself and similarity of surface properties etc.
