In this study, we performed various extraction condition experiments such as types and concentrations of extractants, amounts of extraction sources, pretreatment processes, to optimize the calcium ion extraction for precipitated calcium carbonate (PCC) production. CaO was used as a calcium extraction source, The extraction amount of calcium ions and the particle size of CaO were determined by ICP and SEM results. As a result, 100% calcium ion was extracted when 2 M hydrochloric acid was used as an extractant, and the optimum amount of the extraction source was 6 g. On the other hand, it was confirmed that the reaction time, reaction temperature, particle milling and heat treatment process had no significant effect on the calcium ion extraction amount.
