I. Summary of results: The present invention provides an improved method for digestion and carbonization in the production of high-purity basic magnesium carbonate and high-purity magnesium oxide from dolomite, and improves the yield of basic magnesium carbonate produced by dolomization and the increase of the yield of magnesium oxide Extraction rate, while solving the dolomite carbonization method is difficult to completely separate the calcium and magnesium technical problems. The invention has the advantages of simple process and easy control, high extraction rate of magnesium oxide and high product purity.
