Worldwide Occurrence of Magnesite and Brucite

Magnesite deposits are natural occurrences of concentrations of magnesium carbonate with purity levels of about 90-95%, and they typically have 

TABLE 2.2 Worldwide Reserves of Magnesite (Million Tonnes) 

In addition to those deposits listed in Table 2.2, magnesite is also found in Spain, Pakistan, and the Sudan. Deposits with reported reserves of less than one million tonnes occur in Mexico, Iran, the Philippines, Australia, Egypt, and the Republic of South Africa. Small deposits have also been found in Cuba, Norway, Sweden, Poland, Scotland, France, Italy, Kenya, and Tanzania. The dominant producers of magnesite are North Korea, China, Slovakia, Turkey, Russia, Austria, and India, which together account for 75% of world output.
