摘要
该矿石中银以多种分散状态与锰、铁矿物共生。不同流程结构的试验表明，“原矿破碎至２ｍｍ后分级磁选”工艺可获得含Ａｇ３０６ｇ／ｔ、Ｍｎ１４．１９％的混含精矿，Ａｇ、Ｍｎ回收率分别为８６．３６％、９３．６２％。
Ag within the ore has several distribution phases associated with manganese minerals and iron minerals.Tests of different flowsheet shown that the bulk concentrate containing 306 g/t Ag and 14.19%Mn can be obtained with recovery of 86.36% and 93.62% respectively by the process of 'run-of-mine ore reduces its size to 2mm then classification and magnetic separation'.
