对银离子催化细菌浸出黄铜矿进行了研究。在银离子存在下 ,矿粒越细 ,浸出率就越高 ;浸出溶液pH值在 1.5～ 2时浸出率较高 ;银离子浓度在 10mg/L时浸出效果最好。在实验范围内 ,不论银离子初始值大小如何 ,银离子在加入浸出体系后主要是以硫化银形式存在 ,以离子形式存在于溶液中只占很小一部分。 The leaching of chalcopyrite from silver ions catalyzed by bacteria was studied. In the presence of silver ions, the finer the mineral particles, the higher the leaching rate; the leaching solution has a higher leaching rate at pH 1.5 to 2; the leaching effect is best at a silver ion concentration of 10 mg / L. In the experimental range, regardless of the initial silver ion size, the silver ions mainly exist in the form of silver sulfide after they are added to the leaching system, and only a very small part of the ions exist in the solution.
