product. The magnesium oxide used in the tanning industry contains an average of 0.5% Fe 2 O 3, which is a fairy low and inert component in the tanning process (compared to CaO), but even at low concentrations (0.2%) the Fe 2 O 3 is sufficient to turn the MgO a beige / brown color. Magnesium oxide from water origin usually contains no Fe oxides
At present, the research on the production process of fused magnesia mainly focuses on the following aspects: energy consumption, grade rate of fused magnesia, waste heat recovery and utilization rate, failure rate of the smelting process, power supply quality, management of the production process.
Magnesium is the eighth most abundant element, and equals about two per cent of the earth's crust and typically 0.12% of seawater. Both MgCO 3 and Mg(OH) 2 are converted to MgO by calcination. The thermal treatment of the calcination process affects the surface area and pore size and hence the reactivity of magnesium oxide formed.
