This paper deals with concentration of hematitic-limonitic iron ores. The ore sample obtained from Karakuz (Turkey) contain:. about 40-46 I Fe.
The results demonstrate that blending of the high-grade hematitic Roy Hill WHIMS concentrate into the fines product can maintain overall sinter quality and positively influence granulation …
The paper describes the development of a process for producing salable iron and manganese pellet concentrates from low-grade manganiferous iron ores of the Cuyuna range by a two …
Bench-scale and continuous testing were performed to adapt the anionic process for flotation of calcium activated silica to the fine-grained hematitic-goethitic jaspers from the Marquette …
Roasting of hematitic ore has been tested in boosting of magnetic concentration of hematitic iron ore. Coke rate, roasting time, and temperature were analyzed at several levels …
T-he procedure for pelletizing non-magnetic, eg., hematitic, concentrates and similar finely divided nonmagnetic oxidic compounds of iron is substantially the same as the above identified …
