通过由氰化尾渣中硫铁矿难浮选的机理着手，研发出新型药剂 GS-01。通过采用实验室自制药剂 GS-01，当 pH 值为6.8、矿浆浓度为30%、GS-01用量为3000 g/t、丁基黄药用量为300 g/t，2#油用量为80 g/t 时，通过一粗二精二扫的浮选工艺流程，可达到精矿中硫品位为48.36%，回收率为93.77%的最终指标。GS-01由组分 A、B 组成，通过浮选试验、红外光谱测试、沉降试验等分析得到：加入药剂后可以使硫铁矿与微细粒脉石矿物分散开来，暴露出更多的硫铁矿表面，进而通过氧化溶液中简单氰化物和络合亚铁氰络合物起到脱氰作用。

A main valuable component in the residue of cyanide is pyrite, which is an important source to produce sulfuric acid. While the low concentration of pyrite in the residue of cyanide makes it difficult to produce sulfuric acid directly. To fully utilize the valuable component in cyanide tailings, the pyrite in it has to be enriched. However, it is difficult to recycle pyrite from cyanide tailings by flotation, due to the remained cyanide and the micrograined gangue. Based on our knowledge about the reason for the difficulties to recycle pyrite from the residue of cyanide, a new recipe agent named GS-01 was synthesized. With the use of GS-01, we can get a sulfur concentrate with 48.36 % S grade and 93.77 % S recovery using a flotation process consisting of one roughing, two cleaning and two scavenging, where the density of the pulp is 30 % and pH of the pulp is 7, the addition of GS-01 is 3000 g/t, the addition of xanthate is 300 g/t and the addition of 2#oil is 80 g/t. GS-01 consists of two parts , A and B. The mechanism for the successful recovery of pyrite by GS-01 was studied by infrared spectrum testing and sedimentation test analysis. The results indicated that part A can disperse the fine slime to expose more fresh surface of pyrite. Part B can destroy the cyanide of pulp by oxidating the simple cyanide and forming complexion formation with ferrocyanide.
