magnetic roasting of iron ore

Suspended Magnetic Roasting Study of Fine Grained Suspension roasting furnace was used as the reactor of magnetic roasting of fine grained siderite and the N2 was used as the conveying gas The results show that the siderite ore be roasted at the conditions of gas velocity is 1 7m/s and the roasted time is 12 35s according to magnetic separation can obtained iron concentrate grade is -magnetic roasting of iron ore-,Magnetite Ore Magnetite Iron Ore Iron Ore Mining ProcessMagnetite ore is a ferromagnetic material with the chemical formula Fe3O4 and is one of several types of iron oxide It is a ubiquitous mineral in many parts of the world including Australia the USA Canada South Africa Mozambique and many other countries across most of the world s continents ……
