摘要:
采用化学分析、偏光显微镜及扫描电子显微镜等检测手段，对山东某金矿红布矿区原矿、马塘矿区原矿和选矿厂混合原矿进行了工艺矿物学研究。结果表明：混合原矿金品位为2.52 g/t、银品位为2.29 g/t；金属矿物主要为黄铁矿，脉石矿物主要为石英、长石；载金矿物主要为黄铁矿和少量黄铜矿。红布矿区原矿中金矿物种类为含银自然金，平均粒度为18.58 μm，金矿物嵌布状态主要为包裹金。马塘矿区原矿中金矿物种类为自然金，平均粒度为9.48 μm，金矿物嵌布状态主要为包裹金。根据工艺矿物学研究结果，推荐红布矿区和马塘矿区原矿配矿比例为3∶1，为选矿工艺优化提供了矿物学依据。

Abstract:
Chemical analysis,polarizing microscope and scanning electron microscopy and other detection techniques are used to carry out process mineralogy study on the raw ores of Hongbu and Matang mining area and the mixed raw ores of the concentrator in a gold mine from Shandong.The results show that the gold grade of the mixed raw ores is 2.52 g/t,and the silver grade is 2.29 g/t;the metal minerals are mainly pyrite,and the gangue minerals are mainly quartz and feldspar;the gold-bearing minerals are mainly pyrite and a small amount of chalcopyrite.The type of gold minerals in the raw ores of Hongbu mining area is silver-bearing native gold,with an average particle size of 18.58 μm.The occurrence of gold is mainly wrapped gold.The type of gold minerals in the raw ores of Matang mining area is native gold,with an average particle size of 9.48 μm,and the occurrence of gold is mainly wrapped gold.Based on the results of the process mineralogy study,it is recommended to use the raw ore blending ratio of Hongbu mining area and Matang mining area 3∶1,in order to provide process mineralogy basis for the optimization of ore-dressing processes.
