| description | The invention discloses a method for preparing battery-grade lithium chloride through spodumene pressure leaching. Spodumene is used as a raw material; the method comprises the following preparation steps: carrying out pressure leaching reaction on beta spodumene subjected to high-temperature calcination transformation, a CaCl2 solution and a small amount of Ca (OH) 2 solution at high temperatureand high pressure; carrying out flash evaporation and filter pressing to obtain a LiCl crude solution, removing calcium by Na2CO3, filtering to obtain a LiCl solution, carrying out acidification steamstripping, evaporation concentration, cooling sodium precipitation, sodium removal by an ion adsorbent, evaporation crystallization, separation and drying to finally obtain battery-grade lithium chloride; the method has the advantages of simple process, simple and effective sodium removal method, low impurity content, low energy consumption, low cost and stable product quality.
