东坪金矿工艺矿物学研究

摘要

Combined with the actual situation of concentrator in Dongping gold mine, the process mineralogy of the undressed gold ore with Au grade of 3. 62 g/t (0 ~ 16 mm) is studied. By using mineral automatic analyzer (MLA) and other comprehensive methods, the characteristics such as types of gold minerals, distribution characteristics, embedment conditions, occurrence status and etc. are investigated, which provides corresponding basic data in time for the dressing production, and provides scientific basis for improving gold recycle rate as well.%结合东坪金矿选矿厂的实际情况,对其提供的金品位在3.62 g/t的原矿矿石(0～16 mm)进行了工艺矿物学研究,通过使用矿物自动分析仪(MLA),运用综合手段查明了矿石中的金矿物的种类、分布特征、嵌布状态及赋存状态等特征,及时为选矿生产提供了相应的基础数据,为提高金的回收利用率提供科学依据.
