摘　　要：对广西某锰银浮选精矿进行了工艺矿物学的研究,查明了锰银浮选精矿的工艺矿物学性质。该锰银精矿的主要金属矿物为硬锰矿、软锰矿、黄铁矿、褐铁矿、少量毒砂、赤铁矿和闪锌矿;脉石矿物主要为石英、方解石及粘土矿物等。精矿的粒级分布:0.152～0.088mm粒级的颗粒占10.21%,0.088～0.074mm的颗粒占11.45%;<0.074mm的颗粒最多,占60.95%。主要载银矿物有硬锰矿、软锰矿、褐铁矿、方铅矿、黄铁矿和闪锌矿。主要含银矿物是自然银、辉银矿、角银矿。The process mineralogy of manganese-silver concentrate in Guangxi province was studied in this paper, and the occurrence state of silver in the concentrate was found out. Main metallic minerals in the manganese-silver concentrate were psilomelane, pyrolusite, pyrite, limonite, and a few arsenopyrite, hematite and sphalerite. Main gangue minerals were quartz, calcite and clay minerals. The grain size distribution of the concentrate was 0.152-0.088mm accounting for 10.21%; 0.088- 0.074mm for 11.45%; 〈 0.074mm for 60.95%. The main silver-bearing minerals were psilomelane, pyrolusite, limonite, galena, pyrite and sphalerite. Main silver minerals were nature silver, argentite and chaorargyfite.
