after dissolving and digesting lime with water to make lime milk, it is sent to a chloride tower, and the solution is reacted with chlorine to generate calcium chlorate, etc. the reaction solution contains calcium chlorate> 50g/L and calcium hypochlorite <25g/L. alkali sulfide is added to remove free chlorine, filtered, the filtrate is refined, the solution is evaporated and concentrated, cooled and crystallized, centrifuged, dried and crushed to obtain calcium chlorate.
