| titleOfInvention | Method for removing arsenic from ilmenite smoke dust and recycling valuable metals |
| abstract | The invention discloses a method for removing arsenic from ilmenite dust and recovering valuable metals. Leaching ilmenite dust by using strong alkali to obtain leaching solution containing arsenate and zincate and leaching slag containing iron; adding benzyl chloride into the leaching solution to convert arsenate into benzyl arsonate, adding a particle carrier to adsorb the benzyl arsonate, and then carrying out gas floating to separate the benzyl arsonate; neutralizing the flotation residual liquid to separate out a zinc hydroxide product; adding water into the iron-containing leaching slag, stirring and mixing, and then adding a flocculating agent and a collecting agent for flotation to obtain iron ore concentrate. The method not only can achieve the aim of removing arsenic well, but also can recover iron and zinc products, and can realize the resource comprehensive utilization of the arsenic-containing ilmenite smoke dust; the method is simple, rapid, efficient and low in cost, and meets the requirement of industrial production. |
