宜春锂云母矿源充足、价廉、开发前景好.食盐压煮法新工艺具有流程短,锂、钾回收率高,渣量少,所用化工材料NaCl价廉,供应有保障,能耗低,生产成本低等优点.主产品碳酸锂、副产品氯化钾质量均达到国标要求,产出的钠盐,锂母液、洗渣液均可返回利用,流程封闭,三废排放达标. Yichun lepidolite is rich in mineral resources, low cost and good development prospect. The new technology of salt pressure cooker has the advantages of short process, high recovery rate of lithium and potassium, small amount of slag, low cost of chemical materials used, low cost of supply, low energy consumption, Low cost, etc. The main products of lithium carbonate, by-product potassium chloride quality meet the national standard requirements, the output of sodium salt, lithium mother liquor, washing liquid can be returned to use, the process closed, three waste discharge standards.
