抗得弄舍金多金属矿床位于东昆仑成矿带的东南段，金矿体赋存于下二叠统马尔争组火山岩与石炭系浩特洛洼组灰岩的层间断裂破碎带中。控矿构造为以压性-压扭性为主的NWW、NW向断裂。矿石类型主要为重晶石型金铅锌矿，金属矿物主要有黄铁矿、闪锌矿、方铅矿、黄铜矿、黝铜矿和斑铜矿等，矿石中有益组分为Pb、Zn、Ag、Cu和Ba。金矿物主要为银金矿，含少量自然金。赋存状态以粒间金为主，其次为包裹金，裂隙金相对较少。粒度以细粒明金为主，其次是微粒金，与脉石关系密切，解离较难，单纯浮选很难有效回收矿石中的金，应采用氰化与浮选相结合的方法回收金。

Kangdenongshe gold-polymetallic deposit locates at the southeast section of the East Kunlun metallogenic belt,whose gold orebody occurs in the interlayer fracture zone between the lower Permian series of Ma’erzheng Group volcanic and the carboniferous system of Hao’teluowa Group limestone.The ore-controlling structure features NWW and NW ruptures mainly caused by compression-compression and twists.The major ore types are barite-type gold,lead,and zinc ore,while the metallic minerals mainly include pyrite,sphalerite,galena, chalcopyrite,tetrahedrite,bornite,etc.The beneficial components in the ore are Pb,Zn,Ag,Cu,and Ba.The gold minerals are mainly electrum and a small portion of native gold.The occurrence status is mainly inter-granular gold,followed by inclusion gold,and then a little fracture gold.The gold granularity is mainly fine granule visible gold and particle gold which has a close relation with the gangue and is hardly to conduct cleavage.Pure flotation cannot effectively recycle the gold from the ore,so the combination of cyaniding and floatation is recommended.
