Does Dolomite Produce Magnesium Sulfate
Potassium Magnesium Sulfate: Langbeinite
Therefore, it's unsuitable for dissolving and applying through irrigation systems unless its finely ground. It has a neutral pH, and does not contribute to soil acidity or alkalinity. 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.

Magnesium Carbonate Production Process from Dolomite
Because the production cost of dolomite carbonization is low and the process is easy to control, this method is widely used in China to produce light magnesium carbonate. The production process is to crush the dolomite ore and then calcinate it at about 1000°C.

Dolomite and Dolomitization | SpringerLink
The crystal structure of dolomite is similar to calcite with Mg ions substituting for Ca in every other layer. To accommodate this substitution, due to differences in bond lengths between Ca–CO 3 and Mg–CO 3 (238 pm versus 208 pm, respectively), CO 3 in the Mg layer is uniformly rotated about the threefold axis relative to calcite (Reeder and Wenk, 1983).
