slag is very important. This work focuses on investigating wetting and interfacial permeability of molten iron and prereduced ilmenite pellet systems, so as to clarify the separation process of iron... of 1553 K. It was seen clearly that the contact angle of molten iron with prereduced ilmenites is time-independent, indicating the wetting is a nonreactive process. 3.4 Interfacial permeability of molten......
