production of magnesium sulfate from dolomite

Preparation of high purity magnesium oxide from dolomite

Magnesium oxide is then separated physically from the calcined dolomite by sieving or air separation. Magnesium bearing carbonate ores contain varying amounts of silica, iron oxide, alumina and calcium silicates, carbonates and oxides. In chemical beneficiation methods, magnesium is dissolved as salt, the insoluble impurities are removed by ...

Potassium Magnesium Sulfate: Langbeinite | Mosaic Crop

This differs from other common Mg sources such as dolomite, which will increase soil pH, and from elemental S or ammonium sulfate, which will lower the soil pH. Growers frequently choose langbeinite in situations where a fertilizer free of chloride is desirable, such as with crops sensitive to it (like some vegetables and certain tree crops).

Under such conditions, using dolomite to raise the pH to 6.0–6.5 furnishes Mg at the same time. Soil application of Mg sulfate or oxide can successfully correct Mg deficiency when soil pH is raised. Soil salinity, fertilizers high in potassium salts, and manures have induced or aggravated Mg deficiency. Magnesium deficiency can also be attributed
