含硫微细浸染型金矿石是我国重要的黄金资源，这种金矿石中细粒金或次显微金呈包裹或浸染状存在于黄铁矿、砷黄铁矿等硫化物中，细磨亦难分离。这些矿物的包裹，阻止了金粒与浸金剂有效接触，妨碍了金的浸出，采用常规氰化法直接氰化，金提取率低于40%，属于极难处理金矿。这类金矿在我国分布较广。采用选矿方法富集载金硫化矿，通过化学预处理后再用氰化法浸金，是目前处理该种矿物常用且有效的方法。因此，选矿回收载金矿物是处理该种矿石的重要环节，是提高金的总回收率的重要保证。
矿石中金主要以微细粒金嵌布于以黄铁矿为主的硫化矿物中，由于黄铁矿具有较好的可浮性，可通过浮选法回收黄铁矿来富集金。针对矿石中硅酸盐含量高的特点，进行了详细的探讨试验，提出采用Na2CO3为pH调整剂、Na2SiO3为脉石的抑制剂、CuSO为硫化矿活化剂，丁铵黑药和丁黄药为捕收剂的常规的浮选工艺流程，开展了小型浮选试验浮选，也为该矿的开发提供依据
Sulfur fine disseminated gold ore is an important gold resource in our country, this kind of gold ore fines or sub micro Jin Cheng inclusions or disseminated in pyrite, pyrite and other sulfides, fine grinding is difficult to separate. The inclusions of these minerals prevent the gold particles from effective contact with the gold leaching agent, which hinders the gold leaching, and the gold extraction rate is less than 40%, which is very difficult to treat. This kind of gold deposit is widely distributed in china. The mineral processing method is used to enrich the gold bearing sulphide ore, and then it is used to treat this kind of mineral. Therefore, the mineral processing of gold bearing minerals is an important part of the treatment of the ore, is an important guarantee to improve the total recovery rate of gold.

Gold is mainly distributed in micro fine grained gold in pyrite dominated sulfide minerals, due to the good flotation of pyrite, can be recovered by flotation of pyrite to enrich gold. According to the characteristics of high silicate content of the ore, the careful study of the test, the Na2CO3 was used for pH adjustment agent, sodium silicate gangue inhibitor and CuSO sulfide ores activator, ammonium butyl aerofloat and butyl xanthate as collecting agent to a conventional flotation flowsheet and small type flotation flotation test was carried out, the basis is provided for the development of the mine
