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。

In the traditional Precision casting, the wax pattern needs to be pre-produced by using steel or aluminum mold. Producing mold is usually very difficult, which takes a long time. Particularly when there is some complex surface in the mold, advanced machining center is needed and the production costs will be greatly increased.

在传统铸造工艺中，为了得到蜡模需要预先生产钢制或铝制的模具，而制造模具通常是很困难的，生产周期很长，尤其是当模具上有很复杂的曲面时需要用先进的加工中心才能制造，将大大提高整个工艺的成本。
