Superfine slag powder and preparation method thereof
The invention relates to the technical field of comprehensive utilization of resources, and discloses superfine slag powder and a preparation method thereof. The method comprises the following steps:(1) mixing titanium extraction tailings hot slag with water, and then carrying out dehydration treatment to obtain crude dechlorinated tailings; (2) mixing the crude dechlorinated tailings obtained inthe step (1) with a slurry containing Fe < 3 + >, and then roasting to obtain deep dechlorinated slag; (3) mixing the deep dechlorinated slag obtained in the step (2) with an excitant and a reinforcing agent, and then grinding until the specific surface area is greater than or equal to 400m < 2 >/kg; according to the method, the Fe < 3 + > slurry is adopted for dechlorinating, the technological process is improved, the dechlorinating effect of the titanium extraction tailings is improved, superfine slag powder meeting the national standard requirement can be produced, meanwhile, the production cost is reduced, efficient comprehensive utilization of titanium extraction tailing resources is achieved, ferric chloride and other resources are recycled, and the requirements of the current circular economy policy are met.
本发明涉及资源综合利用技术领域，公开了一种矿渣微粉及其制备方法。该法包括以下步骤：(1)将提钛尾渣热渣和水进行混合，然后进行脱水处理，得到粗脱氯尾渣；(2)将步骤(1)所得粗脱氯尾渣与含有Fe3+的桨体混合，然后进行焙烧，得到深脱氯渣；(3)将步骤(2)所得深脱氯渣与激发剂和增强剂混合，然后磨细至比表面积大于或等于400m2/kg；此方法采用Fe3+的桨体脱氯，并且改进工艺流程，提高了提钛尾渣的脱氯效果，既能生产出符合国家标准要求的矿渣微粉，同时降低生产成本，并且实现提钛尾渣资源的高效综合利用，回收氯化铁等资源，符合当前循环经济政策要求。
