吸附法提锂快洗除镁工艺技术研究

Abstract

Abstract: The adsorption method to extract lithium from saline lake brine and fast leaching for magnesium removal technolo- gy were studied.Results showed taking NaCl solution with mass concentration of 187 g/L as the leaching agent，fast leaching the saturated sorbent at room temperature before washing to remove magnesium ions，controlling the contacting time at 2 min and 2 bed-volume for fast leaching，the brine between the sorbents could be effectively removed to reach good magnesium removing effect.

Key words: adsorption method, lithium extraction, magnesium removal, salt lake brine
