concentration of magnesium oxide (MgO). If the MgO concentration is less than one percent, it is considered a product and no further beneficiation is required. If the MgO concentration exceeds one percent, the ore is directed to a patented heavy media separation plant for MgO removal.

in the ore. After the beneficiation processes, magnesite is subjected to calcination. Depending on the calcination temperature, magnesia is designated as reactive magnesia (700 – 1000 oC), dead/hard burned magnesia (1000 - 2200 oC) and fused magnesia (above 2750 oC).
