Method for preparing superfine slag powder from titanium extraction tailings
The invention discloses a method for preparing superfine slag powder from titanium extraction tailings, and relates to the technical field of mining treatment, the method for preparing the superfine slag powder from the titanium extraction tailings comprises the following steps: step S10, dechlorinating the titanium extraction tailings to obtain dechlorinated titanium extraction tailings; s20, the titanium extraction tailings obtained after dechlorination are subjected to drying treatment, and dried titanium extraction tailings are obtained; s30, a chlorine fixing agent is added into the dried titanium extraction tailings according to the proportion for mixed grinding treatment, and superfine slag powder is obtained; wherein the specific surface area of the superfine slag powder is greater than or equal to 400m < 2 >/kg. The method has the characteristics of simple raw material process and full utilization of solid waste resources. The chlorine fixation technology is effectively adopted, chlorine in the titanium extraction tailings does not need to be removed to 0.06% or below, and the cost is low.
本发明公开了一种利用提钛尾渣制备矿渣微粉的方法，涉及矿山开采处理技术领域，该利用提钛尾渣制备矿渣微粉的方法，包括如下步骤：步骤S10、对提钛尾渣进行脱氯，以获得脱氯后的提钛尾渣；步骤S20、对脱氯后的提钛尾渣进行干燥处理，以获得干燥提钛尾渣；步骤S30、按比例将固氯剂加入至干燥提钛尾渣进行混磨处理，以得到矿渣微粉；其中所述矿渣微粉比表面积大于等于400m2/kg。本本发明原料工艺简单，充分利用了固废资源特点。有效采用固氯技术，不必将提钛尾渣中氯脱除到0.06％以下，成本低廉。
