摘要
勉略宁地区为南秦岭重要的内生多金属矿集区,位于该区的陕西宁强某金矿矿石属于硅化千枚岩型,通过对矿石的化学组成、矿物组成、结构构造,重要矿物的粒度、形态及嵌布关系等工艺矿物学研究,确定该矿床矿石矿物组成简单,主要为黄铁矿;脉石矿物以石英为主,次为钠长石、绢云母等;自然金形态多样,属于中粗粒型金矿石,且多分布在矿物粒间。这一研究结果为选矿工艺研究方案的选择提供了理论依据。
The Mianluening region is an important endogenic multi metals resources area in the southern Qinling region, Shaanxi Province. The gold ore located in the Ningqiang country area belongs to the silicified phyllite type ore. Through the mineralogi cal studies on the characteristics of the gold orein cluding chemical compositions,mineral compositions, ore texture and structure, gran ularity of key minerals, physical forms and embedding features of minerals etc. , it is concluded that the mineral composition is simple, mainly the pyrite mineral; quartz is the main gangue mineral, minors are albite and sericite etc. The forms of native gold varies, the gold ore belonging to the medium coarse grain native gold ore. The native gold mainly distributes among the mineral grains. This study can provide a technological basis for the selection of the processing technology.
