It was determined through a large amount of beneficiation test to adopt chloridizing roasting-cyanide leaching as the principle beneficiation flowsheet for a certain silver-manganese concentration ore. The test results indicate that we can get the leaching rates of silver is up to 88.54% ,firing temperature was 750℃, firing time was 30 minutes and sodium cyanide was 6kg/t and lixiviating time was one hour.%通过对某银锰精矿的选矿试验研究,确定中温氯化焙烧-氰化浸出作为选矿原则流程.试验结果表明,在氯化焙烧采用中温750℃、焙烧时间30min以及氰化钠用量6kg/t、浸出时间1h的条件下,银的浸出率可达88.54%.
