Impurity removal method for potassium feldspar powder
The invention relates to the technical field of potassium feldspar, in particular to an impurity removal method for potassium feldspar powder, which comprises the following steps of: S1, ball milling:crushing raw ore, putting the ore into a ball mill for ball milling, and adding deionized water before ball milling to obtain ball-milled slurry; S2, magnetic separation: performing high-gradient magnetic separation on the ball-milled slurry to obtain magnetic separation slurry; S3, centrifugal separation: carrying out ultrasonic treatment on the magnetic separation slurry for 15-30 minutes, andcarrying out centrifugal separation after the ultrasonic treatment is finished; S4, freeze-drying treatment: carrying out freeze-drying treatment on the collected filter cake; and S5, hydrothermal treatment: putting the freeze-dried powder into a sulfuric acid solution, and then pouring the mixed solution into a hydrothermal reaction kettle. The potassium feldspar impurity removal method providedby the invention has the advantages that the impurity removal steps are simple, the pollution of the adopted raw materials to the environment is small, the cost of the raw materials is relatively low,the method is suitable for popularization and application, and the potassium feldspar obtained by the method has the characteristics of high whiteness and low iron content.
本发明涉及钾长石技术领域，尤其涉及一种钾长石粉末的除杂方法，包括以下步骤：S1、球磨：将原矿石进行破碎处理，再将矿料投入球磨机中进行球磨，球磨前加入去离子水，得到球磨浆料；S2、磁选：将所述球磨浆料进行高梯度磁选，得到磁选浆液；S3、离心分离：将磁选浆液先经过超声处理15‑30min，超声处理完毕后，进行离心分离；S4、冻干处理：将收集的滤饼进行冻干处理；S5、水热处理：将冻干处理后的粉末放置到硫酸溶液中，然后将混合液倒入到水热反应釜中。本发明提出的钾长石除杂方法，除杂步骤简单，采用的原材料对环境污染小，且原材料的成本相对较低，适合推广使用，并且，经过本方法得到的钾长石具有白度高、含铁量低的特点。
