腊梅斯貝克(Rammelsberg)富矿的銅品位一般是1—2％,平均約1.3％,鉛为7—8％,鋅为16—18％。該区矿石皆为硫化矿物,其中在选矿技术上有意义的矿物仅为閃鋅矿、方鉛矿、黄銅矿和黄鉄矿。此外,黝銅矿也占有一定的地位,因为有少量銅存在于这种矿物中。处理象腊梅斯貝克这样的复杂矿石是极为困难的。世界上只有少数矿床具有类似的矿石。关于北美、南美和非洲复杂矿石的选別方法,麦奎斯頓(McQuiston)已有过报导。他指出,有些企业已改用了适合特殊矿石类型的选矿方法。
Copper grades in the Rammelsberg bauxite are generally 1-2%, with an average of about 1.3%, lead of 7-8% and zinc of 16-18%. The ores in the area are all sulphide minerals, of which only the sphalerite, galena, chalcopyrite and cassiterite are the minerals of interest in mineral processing technology. In addition, tetrahedrite also occupies a certain position, because a small amount of copper is present in this mineral. It is extremely difficult to process complex ores such as Rhemesbeck. Only a few of the world's deposits have similar ores. McQuiston has reported on the selection of complex ores in North and South America and Africa. He pointed out that some companies have switched to beneficiation methods suitable for special ore types.
