Extraction of lithium from alkali leaching solution of rare earth molten salt electrolytic residue by gas-liquid reaction crystallization method was studied. The effects of temperature, carbon dioxide flow rate, pH, aeration time and stirring speed on the carbonation rate were investigated. The results show that the carbonization rate is about 83% under the optimized conditions of temperature of 90 ℃, CO2 inflow rate of 1 000 mL/min, ventilation time of 20 min and stirring speed of 450 r/min. The carbonization rate increases first and then decreases with the increase of CO2 inflow rate and ventilation time. The product is lithium carbonate with no impurities and high crystallinity. This method overcomes the problems of local supersaturation and uneven crystal size caused by traditional precipitation method, and provides a new technical path for the resource treatment of complex alkaline lithium-containing wastewater. And it can promote the rare earth smelting industry to the direction of green, recycling, high value development.

研究了采用气液反应结晶法从稀土熔盐电解渣碱浸液中提取锂元素。考察了温度、CO2通入流量、pH、通气时间及搅拌转速等因素对碳化率的影响。结果表明:在温度90 ℃、CO2通入流量1 000 mL/min、通气时间20 min、搅拌转速450 r/min优化条件下,碳化率约为83%;碳化率随CO2通入流量增大和通气时间延长呈先升后降趋势;反应所得产物为无杂质、高结晶度的碳酸锂。该法克服了传统沉淀法易产生局部过饱和、晶体粒度不均等问题,可为复杂碱性含锂废水资源化处理提供一种全新的技术路径,推动稀土冶炼行业向绿色、循环、高值化的方向发展。

研究了采用气液反应结晶法从稀土熔盐电解渣碱浸液中提取锂元素。考察了温度、CO2通入流量、pH、通气时间及搅拌转速等因素对碳化率的影响。结果表明:在温度90 ℃、CO2通入流量1 000 mL/min、通气时间20 min、搅拌转速450 r/min优化条件下,碳化率约为83%;碳化率随CO2通入流量增大和通气时间延长呈先升后降趋势;反应所得产物为无杂质、高结晶度的碳酸锂。该法克服了传统沉淀法易产生局部过饱和、晶体粒度不均等问题,可为复杂碱性含锂废水资源化处理提供一种全新的技术路径,推动稀土冶炼行业向绿色、循环、高值化的方向发展。

Extraction of lithium from alkali leaching solution of rare earth molten salt electrolytic residue by gas-liquid reaction crystallization method was studied. The effects of temperature, carbon dioxide flow rate, pH, aeration time and stirring speed on the carbonation rate were investigated. The results show that the carbonization rate is about 83% under the optimized conditions of temperature of 90 ℃, CO2 inflow rate of 1 000 mL/min, ventilation time of 20 min and stirring speed of 450 r/min. The carbonization rate increases first and then decreases with the increase of CO2 inflow rate and ventilation time. The product is lithium carbonate with no impurities and high crystallinity. This method overcomes the problems of local supersaturation and uneven crystal size caused by traditional precipitation method, and provides a new technical path for the resource treatment of complex alkaline lithium-containing wastewater. And it can promote the rare earth smelting industry to the direction of green, recycling, high value development.
