During this process, sodiurtt hydroxide is converted to sodiunt oarhonate. Caioium oxide, aiso known as duiekiirtie, is then added to eonvert the sediurtt earhenate hack to sodium hyfdroxide in order to use it again. in the process, eaieium oarhortate in the torrn ot time mud is ehtained. Lime mud is ntainiy eaieiuin earhonate mixed with water testning a siudge. "the iime mud is then oaioined to retrieve oaioitirn oxide in a time reoovery oyeie. Betore eaieination, the time mud is preterahiy dried to an extent suitahie ter handiing in connection with and in the oaioinatiort process. For exarnpie, the input materiai suoh as iime or iirne mud rnay he puiverized into a povvdei' in connection with the drying. Simiiar processes are as rnentiened appiieahie in other industries.

Gaioination ot oaioitirn oarhonate begins to ooeur at ahout ätit) degrees Ceisius, and rtormaiiy oaioination takes piece at ternperatures in the range QÜG-i titt) degrees Ceisitis, wherehy eaieitirtt oxide and earhon dioxide is formed.
