本发明涉及铁矿石氧化铁的制造方法。 根据一个实施方案，本发明提供一种铁矿石氧化铁的制造方法，该方法包括在由含镍和钴的矿石制造镍 - 铁化合物的过程中从作为滤液生成的氯化铁水溶液中制备氧化铁 通过干湿法精制技术。 该方法包括以下步骤：制备氯化铁水溶液; 用选择性吸附镍和钴的离子交换树脂处理氯化铁水溶液以减少残留在氯化铁水溶液中的镍和钴; 加热并蒸发除去镍和钴的氯化铁水溶液以沉淀氯化铁晶体; 并煅烧沉淀的氯化铁晶体得到氧化铁。

The method for producing iron oxide for the iron ore is disclosed. One embodiment of the present invention, nickel and from a cobalt-containing ore gun, nickel by hydrometallurgical techniques - in the iron oxide preparation method for producing the iron oxide from ferric chloride solution generated in the filtrate in the process of manufacturing the iron compound, iron chloride the method comprising: preparing an aqueous solution; Comprising: in order to reduce the nickel and cobalt remaining in the aqueous solution of iron chloride, an ion exchange process using an ion exchange resin to selectively adsorb the nickel and cobalt; Comprising: by heating and evaporation, precipitated with iron chloride crystals nickel and iron chloride solution of the cobalt is reduced by the ion exchange treatment; And it provides a method of manufacturing the iron oxide ore, comprising the step of obtaining the iron oxide by calcining the precipitated iron chloride crystals.
