Dolomite is recommended to correct calcium and magnesium deficiencies. Depending upon magnesium levels, dolomitic lime can often cause more harm and trouble, however, than its initial cost. Excess magnesium is often associated with soil stickiness, crusting, compaction, reduced aeration, and releasing nitrogen from the soil pound for pound.

Portland cement is one of the most . important products made from limestone. It is essential in many construction appli-cations. The United States is not self-suf-ficient in cement and must import it from


Limestone and Dolomite are closely related sedimentary carbonate rocks. They both comprise calcite minerals. When subjected to heat and pressure, both limestone and Dolomite begin to recrystallize as the temperature rises. Limestone and Dolomite incorporate basic chemistry. Thus, they can be easily separated or crushed into the desired size.


Extracting the dolomite is covered by a government mining agreement with DMC and processing it by a mineral product sharing agreement between the government and PMSC: both contracts good for 25 years. The hauling is covered by an MGB-Central Visayas permit to PMSC, in this case, the shipment of crushed dolomite from Alcoy to Manila.
