Metallurgical and Mineral Engineering
�:
CIE is one of the largest designers and researchers for mineral processing in China’s metallurgical system. For the last half century, CIE has taken part in hundreds of beneficiation tests and research projects, and it has won 58 prizes for scientific progress. CIE has designed over 50 large-sized and medium-sized concentration plants for raw material mines and independent mines of large iron and steel enterprises, enjoying the design and EPC capability for beneficiation projects and comprehensive recovery projects of many kinds of ores including vanadium-titanium magnetite, Daye iron ores, magnetite, hematite, limonite, siderite, various kinds of manganese ores and non-metallic ores. At the same time, its beneficiation engineering design level leads the domestic industry especially its unique advantages in comprehensive utilization of vanadium titanomagnetite and ilmenite beneficiation.
