Magnesium Oxide Calcination Process Magnesium metal refining mature method is Pidgeon magnesium, Pidgeon magnesium metal smelting is the most representative, the most widely used silicon thermal reduction process.
Magnesium is weighed and then heated in a crucible. It reacts with oxygen to produce the oxide. It can be shown that there has been an increase in mass. The results can be used to find the formula of magnesium oxide and two methods are described for doing .
Desulphurisation. Additionally, the wet process, in contrast to the other, allows to obtain as a reaction product gypsum (product for resale), If the method uses a neutralizing reagent based on lime, while the product of the other installations (dry and semidry) are waste to landfills.
Magnesium hydroxide precipitates, while calcium hydroxide remains in solution. Magnesium hydroxide is filtered off and on heating readily forms the pure the oxide. Conversion to magnesium chloride is achieved by heating the oxide, mixed with carbon, in a stream of chlorine at a high temperature in an electric furnace (Figure 1).
An improved magnesium oxide (MgO) flue gas desulfurization process and its comparative economics are described. Innovations made include the use of a spray dryer, a cyclic hotwater reheater, and a coalfired fluidizedbed reactor for regeneration of the MgO absorbent.

A new simultaneous desulfurization and deoxidation process of molten steel with magnesium vapor produced in situ by aluminothermic reduction of magnesium oxide is proposed. The pellets composed of MgO and Al are charged into an immersion tube and the magnesium vapor produced in situ by aluminothermic reduction of magnesium oxide is injected directly into molten steel to react with the .
desulfurization reagent. However, the cost of extracting the alkali from the ash in high pressure and temperature stainless steel plant is likely to make these materials expensive reagents. Minerals (potassium, calcium, sodium and magnesium) appear in the unburned biomass in the form of salts are converted into their oxides during the burning process.
This process produces a sorbent for use in desulfurization of coal gas. A zinc titanate compound and a metal oxide are mixed by milling the compounds in an aqueous medium, the resulting mixture is dried and then calcined, crushed, sleved and formed into pellets for use in a movingbed reactor.
The production of Zinc oxide desulfurization process is zinc sulfate (ZnSO 4) which is the raw material for zinc smelting. So the zinc oxide wet flue gas desulfurization (WFGD) process is very suitable for the nonferrous metal smelting industry.

Magnesium oxide flue gas desulfurization (FGD) is a regenerable process. The sulfur dioxide (SO2) in the flue gas is absorbed by a magnesiumbased slurry, and the resulting magnesium sulfite (MgSO3) is calcined to regenerate magnesium oxide (MgO), which is recycled back to the power plant for reuse in the scrubbing section.
High pure magnesium oxide refers to the content of MgO reached more than 98%. And the active magnesium oxide refers to the ability to participate in physical or chemical process, the different activity mainly depends on the size of the magnesium oxide crystallite, incomplete structural and other factors. The applications of pure magnesium oxide.
