Process of flotation of acture ore is the following: firstly, adding Na_2CO_3, ZnSO_4, CSU-1 to the pulp while grinding, and thus in this condition of low Eh, marmatite is inhibited; Secondly, adding CSU-1 to the pulp out of grinding machine, then amesonite and iron sulfur mineral can be flotated using diethyldithiocarbamate as collector; High quality lead and antimony concentrate can be got by adding CSU-1 and calcareousness; Lastly, marmatite is flotated by adding calcareousness, CuSO_4, xanthe, and D-250 to get zinc concentrate.

小型试验研究表明，首先在脱硫粗选作业只加入适量的Na_2CO_3、ZnSOO_4、和CSU-1至磨矿机，利用磨矿机的研磨和磨机中的低电位环境，使铁闪锌矿受到抑制，而最容易浮的脆硫锑铅矿和黄铁矿、磁黄铁矿等硫化矿物则依然具有可浮性；在磨机出来的矿浆中分别加入CSU-1进一步抑制易浮的铁闪锌矿，然后加入乙硫氮将脆硫锑铅矿和硫化铁矿快速浮净，加入石灰和CSU-1，浮选分离出高质量的铅锑精矿；接着添加石灰、CuSO_4、黄药及2~#油选别铁闪锌矿。

Cu~2+ can activate marmatite . Eh of pulp has great effect on the buoyancy of them. New inhibition regeants named CSU-1 can inhibitmarmatite buoyancy. In high pH value and low Eh, use lot of calcareousness, marmatite can separated from pyrrhppite easily in their concentrate mixture.

The results show that jamesonite and pyrrhotite have good floatability in the pH range of 2-10 and marmatite has good floatability in the acid and it is difficult to separate these minerals. In the pH range of 6-8, the separation of jamesonite and pyrrhotite, marmatite is possible when using mercaptoacetic acid and mercaptoethanol as depressants. In case of the presence of Cu2+ ion, however, it is difficult to separate the three minerals. Infrared spectrum demonstrates that there are a number of function groups such as —SH,—COOH,—OH in the molecular structure of depressant.

结果表明：用丁黄药作捕收剂，脆硫锑铅矿和磁黄铁矿在pH 2~10范围内都有良好的可浮性，铁闪锌矿在酸性条件下可浮性好，三者分离困难；在pH 6~8之间，采用巯基乙酸和巯基乙醇作抑制剂，脆硫锑铅矿与磁黄铁矿和铁闪锌矿的分离是可能的；但铜离子存在时， 3种矿物之间的选择性分离是难以实现的。

Two original experimental methods have been developed: 1 A procedure of mineralogical analysis of zinc sulphide concentrates which permits to reliably determine the proportion Fe/Zn of marmatite in each concentrate and the proportion of marmatite in...

在此基础上，实验研究了精矿中的铁对精矿的半导体性质的影响规律，应用半导体电化学原理讨论了精矿铁含量对精矿的直接浸出的影响机理。

在开路电位条件下，铁闪锌矿表面存在双乙硫氮和乙硫氮金属盐，但不能有效地附着在电极表面。

The experimental results proved the intermediate product of H2S in the leaching of marmatite. The results also showed that oxygen, element sulfur disperser as well as chloride ions could accelerate the electrochemical oxidation of marmatite in sulfuric acid. The electrochemical oxidation of sphalerite was retarded but that of marmatite was promoted with the increase of acidity.

结果表明：在铁闪锌矿浸出过程中有H2S中间产物生成；通氧、元素硫分散剂以及氯离子引入浸出体系均能明显促进铁闪锌矿的电化学氧化；随硫酸浓度升高，铁闪锌矿的电化学氧化不断加强而闪锌矿的电化学氧化受抑。

Under initial pH value of 1.6, Fe(superscript 3+) concentration of 8.58 g/L and temperature of 70℃, after eight hours stirring leaching with the Fe(superscript 3+) solution made by biochemical oxidation, the leaching rate of marmatite was above 90% when pulp density was 3%, the leaching rate marmatite was up to 95.18% when pulp density was 1%.

菌生Fe(上标 3+)浸矿剂对铁闪锌矿的浸出表明，在初始pH=1.5、Fe(上标 3+)浓度为8g/L、温度为70℃的条件下浸出8h，当矿浆浓度小于3%时，浸出率可达90%以上，其中矿装浓度为1%时的浸出率高达95.18%。
