calcium chloride sintering of iron ore

Calcium ferrite formation characteristic during iron ore .

Abstract. It is generally known that the large formation amount of calcium ferrite is favorable for the iron ore sintering. The effects of sintering temperature and O 2 content of inlet gas on the calcium ferrite formation characteristic of typical iron ores, including hematite, limonite, specularite and magnetite, were investigated. And the effect of O 2 content on the microstructure of the .

Calcium chloride - Wikipedia

Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl 2.It is a white coloured crystalline solid at room temperature, highly soluble in water.. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl 2 (H 2 O) x, where x = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and dust control.
