Common types of iron ore are magnetite, hematite, limonite and siderite. Among them, hematite, as a weak magnetic iron ore, has uneven particle size and high content of fine particles. Hematite ore is an important iron ore resource in my country. In the early 1960s, hematite ore was mainly processed by roasting-magnetic separation …
Preparatory stage: Crushing and grinding the ore blocks with a size of several meters into ore particles with a size of several millimeters.In this process, you need to use many crushing equipment, screening equipment and grinding equipment. If the ore contains a lot of soil impurities, you also need to wash and deslim the ore, and use ore washing …
However, some studies have focused on beneficiation of Indian iron ore fines and slimes using wet high intensity magnetic sep-arator, spirals, flotation, and selective flocculation [ 3, 7, 12, 14, 15,21]. Till date, there is no specific study with detailed charac-terization for beneficiation of Indian iron ore fines having ultra-fine liberation ...
