The European Magneseti / Magnesai Industry
Magnesia production no matter which type has a calcination step that requires heating the magnesia up minimum 1 000°C. In addition electricity consumption is also present in mining and processing of the raw magnesia. Magnesia produc- tion therefore is very energy and electricity intensive. Jan 01 2013 · Magnesia (magnesium oxide MgO) is mainly produced from the calcination of magnesite in a process similar to the production of lime from limestone. A smaller proportion of the world s MgO production comes from seawater and brine sources.
