Calcium Magnesium Oxide or Dolime is a product based on Dolomite stone, which is similar to Limestone or Dolomitic Limestone, but contains a fix ratio of Mg and Ca in the form of CaMg(CO3)2 , has a dense structure, non-crystalline and is available various colors mostly in white and grey,

Dolime is calcined at temperatures somewhat lower than limestone. During the calcination Carbon Dioxide (CO2) gas is released and first MgO and later CaO are formed. Dolime contains MgO minimum 32% and up to 38%, and CaO minimum 55% up to 62%.

Dolime finds it use in the steel idustry, acting as a flux agent alongside with quicklime. The CaO content of the Dolime will act similarly to quicklime, but the MgO part’s use us to saturate the EAF bath with Magnesium, so that the dissolution of the Mg from the refractory wall of the EAF is minimized, resulting in a greatly prolonged ( 5x up to 10x ) refractory lifetime, reduced downtime, and overall very significant operational cost savings for the steel plant.

We deliver Dolime in Lumps at medium-sized 10-65 mm and briquettes in uniform 40mm sizing, either in jumbo bags weight customized to client requirements of bulk.
