Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

    Why the Extraction of Copper from Chalcopyrite is so

    About 3/4 th of Copper (Cu) produced in the world has come from Chalcopyrite (CuFeS 2), but it is the lowest standard ore of Copper. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.get price

    Extraction of Copper from Chalcopyrite Concentrates
