Method for recovering lepidolite
The invention discloses a lepidolite recycling method which comprises the following steps: S1, adding sodium sulfate, calcium carbonate and calcium sulfate into lepidolite, and uniformly mixing; s2, roasting the material obtained by mixing in the step S1, wherein the center temperature of the material in the roasting process is 1250-1300 DEG C; s3, carrying out wet leaching on the hot sintered ore sintered in the step S2; and S4, drying the leaching residues obtained in the step S3, and using the dried leaching residues as raw materials for cement production. According to the present invention, the existing lepidolite roasting ingredients are changed, the ingredients mixed with the lepidolite are changed, the sodium-potassium insoluble hard rock generated in the traditional lepidolite roasting process can be converted into the calcium-based aluminosilicate through the pyrogenic roasting, the calcium-based aluminosilicate can be used as the ingredient to be supplied to the cement plant as the raw material, and the potassium element is completely converted into the soluble salt from the mica.
本发明公开了一种锂云母的回收方法，包括以下步骤：S1.为向锂云母中添加硫酸钠、碳酸钙、硫酸钙,混合均匀；S2.将S1中混合得到的物料进行焙烧，焙烧过程中物料中心温度为1250‑1300℃；S3.对S2中烧结后的热烧结矿进行湿法浸出；S4.S3中浸出渣干燥后，作为水泥生产的原料。本发明通过对现有锂云母焙烧配料进行改变，通过改变混入锂云母的配料成分，通过火法焙烧就能将传统锂云母焙烧过程产生的钠钾不溶性硬岩转化为钙基硅铝酸盐，并可作配料供给水泥厂当原料，钾元素从云母中全部转化为可溶性盐。
