Magnetite Kiln Process

Efficient and green treatment of ultrapure magnetite to ...

2021-1-22  Therefore, it is imperative to develop a clean and efficient process to manufacture PMIP with ultrapure magnetite. Coal-based rotary kiln direct reduction process (CRKDRP) is widely used in the production of the direct reduction iron (DRI), has many advantages such as short reduction time (3–4 h), large output (250,000 tond/Y) and low energy ...

Smelting Reduction Characteristics and Mechanism of ...

2021-1-3  The process is composed of two parts: the pre-reduction process of vanadium–titanium magnetite in the rotary kiln and the slag–iron separation process in the pure oxygen bath smelting furnace. Firstly, a certain proportion of vanadium–titanium magnetite, coal and fluxes is made into carbon-bearing pellet in disk pelletizer with some water.

Rotary Kiln in Magnetic-Reduction Roasting

2020-2-14  Rotary Kiln in Magnetic-Reduction Roasting. Magnetic-reduction roasting is a process in which non-magnetic ore is converted by the action of reducing gases to a state in which subsequent magnetic separation can achieve the best balance between recovery and grade. The principal characteristics of the rotary kiln method of magnetic-reduction ...
