Method for purifying albite in spodumene acidified slag
The invention belongs to the technical field of albite purification, and discloses a method for purifying albite in spodumene acidified slag, which comprises the following steps: mixing spodumene acidified slag with water to obtain ore pulp; sequentially carrying out magnetic separation, acid pickling and filtering on the ore pulp to obtain filter residues; and calcining the filter residues to obtain albite. According to the method, the spodumene acidified slag is directly used as the raw material to prepare the albite, so that the production cost is low, not only can resources be recycled, but also color impurities influencing the whiteness of the albite can be effectively removed, and the prepared albite is relatively low in water content and meets the industrial standard of the feldspar for domestic ceramics.
本发明属于钠长石提纯技术领域，本发明公开了一种锂辉石酸化渣中钠长石的提纯方法，该方法步骤为：锂辉石酸化渣与水混合后制得矿浆；对矿浆顺次进行磁选、酸洗和过滤，得到滤渣；将滤渣进行煅烧后得到钠长石。本发明直接以锂辉石酸化渣为原料制备钠长石，生产成本低，不仅能实现资源的回收利用，还能有效去除影响钠长石白度的颜色杂质，且所制得的钠长石含水量较低，满足日用陶瓷用长石的行业标准。
