WIPO Patent Application WO/2018/170767

A1

An ore pellet, a preparation method therefor, and preparation equipment. The mass percent content of components in the ore pellet are: TFe 62.1%-65.82%, FeO 0.2%-0.58%, SiO2 1.9%-6.13%, CaO 0.19%-3.23%, MgO 0.18%-0.52%, and Al2O3 0.58%-2.66%. The preparation method comprises: a sintered ore powder is finely milled to produce a finely milled sintered powder; a pelletized powder and/or a boron-containing pelletized powder and the finely milled sintered powder are blended to produce a fine ore powder; a binding agent is added to the fine ore powder to produce an intermediate mixture; and the intermediate mixture sequentially undergoes pelletizing and roasting to produce the ore pellet. The preparation equipment comprises a miller, a container, a pelletizer, and a roasting system. The sintered ore powder of poorer quality and higher environmental costs is utilized in the preparation to produce the ore pellet of better quality and lower environmental costs, thus creating a simple and favorable approach for the green development of the metallurgical industry.
