铜合金

Sulfide ores with BaSO4 as the main gangue , two kinds of slags , speiss and As-Cu alloy have been identified.

还原熔炼中添加了砷矿物，冶炼的品是砷铜合金，还原熔炼生的砷冰铜（黄渣）等副品中的铜通过返料操作冰铜熔炼工序得以回收。

It is concluded that the new Mn-Cu alloy is feasible to be used as absorber in the high-speed rotary fusee-testing machine by the experiment.

通过实验测试得出新型锰铜合金适合作为高速旋减振部件的结论。
