Abstract

Abstract:

In recent years，with the development of electric vehicles，the demand for lithium products has been rising，and the quality of battery-grade lithium carbonate as an important basic lithium salt for the preparation of lithium battery cathode materials has been closely followed by various enterprises.In the preparation of lithium carbonate by ore roasting acid immersion and salt lake brine evaporation and concentration，the impurity calcium ions were difficult to remove due to their close properties to lithium ions，which seriously affects the purity of the product and reduces the safety performance of the battery，so it is necessary to conduct in-depth research on the calcium removal process.Based on the existing problems，the basic principles，applicable environment and research progress of deep calcium removal were expounded around the chemical precipitation method，the network method，the hydrogenation decomposition method，the ion exchange method and the electrolysis method.By combining with the process conditions and actual achievements in the preparation of lithium carbonate，and focusing on the application scenarios of different calcium removal methods adopted by current major lithium resource development and production enterprises，the advantages and disadvantages of each method were analyzed and summarized.By combining with cutting-edge development，the improvement means of the existing calcium removal process were discussed，in order to provide a reference for the actual production and research of lithium carbonate，deep calcium removal process.

Key words: lithium carbonate, deep calcium removal, calcium removal methods, research progress
