The results indicate that both the precipitates produced by Leptospirillum ferriphium strain DY and Acidirhiobacillus ferrooxidans strain GF are composed of jarosite and ammonium jarosite. However, the content of jarosite in the precipitates synthesized by strain GF is 5.53% higher than that synthesized by strain DY, but the content of ammonium jarosite in the precipitates synthesized by strain DY is 15.24% higher than that synthesized by strain GF.

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。

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。
