摘要： 对广西某锰银矿进行了工艺矿物学的研究,查明了锰银原矿石矿矿物成分.金属矿物主要为硬锰矿、软锰矿、黄铁矿、赤铁矿和少量毒砂、黄铜矿、闪锌矿.矿石的主要结构是隐晶质结构、胶状结构、显微鳞片结构及砂质结构.主要的构造是脉状构造、胶状构造、浸染状构造.精矿中银品位是3 923 g.t-1,锰的赋存状态是独立的锰矿物,锰矿物是硬锰矿和软锰矿.精矿中硬锰矿在0.152~0.088 mm粒级范围内占17%,0.088~0.074 mm粒级范围内占38%;>0.074 mm粒级范围占40%;软锰矿在0.152~0.088 mm粒级范围内占18%,0.088~0.074 mm粒级范围内占35%;>0.074 m...

Abstract: The technological mineralogy of a manganese-silver deposit in Guangxi is studied. Identifying its mineral composition, the metallic minerals are revealed consisting of psilomelane, pyrolusite, pyrite and hematite with a few of arsenopyrite, chalcopyrite and sphalerite. The textures of the manganese-silver ore include aphanitic, colloform, micro-squama and arenaceous textures, and its structures are mainly the vein, colloform and dissemiinated structures. The silver grade of manganese-silver concentration is 3923 g·t-1. The occurrence state of manganese in the deposit is the self-contained manganese mineral including psilomelane and pyrolusite. In the concentration the grain size distribution of psilomelane is 17% in the range 0.152-0.088 mm, 38% in 0.088-0.074 mm and 40% >0.074 mm, while that of pyrolusite is 18% in 0.152-0.088 mm, 35% in 0.088-0.074 mm and 37% >0.074 mm.
