METHOD FOR MANUFACTURING HIGH PURITY Li2CO3 IMPROVED RECOVERY YIELD

摘要

The present invention includes in the process for producing the lithium carbonate in more detail relates to a recovery method is improved high purity lithium carbonate production, the removal of magnesium ion; Removing sulfate ions (SO ₄^2-); Forced evaporation using a forced evaporation step to concentrate the lithium ions; A post-processing step to remove trace impurities remaining after evaporation step to force; And sodium carbonate using the (Na ₂ CO ₃₎ provides a recovery rate of the improved high purity lithium carbonate production process including a carbonation step of carbonation to the lithium ion. ;
