The Production Process Of Magnesium Metal

Magnesium mining

Magnesia is the raw material for magnesium ingots, and its main components are magnesium and oxides. The mining of magnesium ore requires the use of mining technology, including open-pit mining and underground mining. During the mining process, special attention needs to be paid to safety measures and environmental protection requirements.

 Oxidation

The magnesium in magnesia ore is converted to magnesium oxide (MgO) through an oxidation reaction, which is an important step in the production of magnesium ingots. During the oxidation process, magnesia ore needs to undergo high-temperature calcination to reduce magnesium to magnesium oxide.

 Restoration

Reduction is the process of reducing magnesium oxide to magnesium metal (Mg). This step requires a high-temperature and high-pressure reduction reaction, usually by electrolysis or silane method.

 Purification

The quality of magnesium ingots depends on the degree of purification. At present, the electrowinning method is mainly used for purification, in which magnesium ingots are electrogenerated in a specific electrolyte, and impurities and impurities are removed through repeated purification steps, so that the magnesium ingots produced are more pure.

1. Magnesia quality. The less impurities in the magnesia, the higher the yield and quality of the ingots.

2. Oxidation process. The control of oxidation conditions is very important for the subsequent reduction and purification processes.

3. Restore conditions. The reduction reaction requires the control of factors such as reaction temperature, pressure, and the type and amount of reducing agent.

4. Purification steps. The steps and conditions of purification determine factors such as the purity and quality of the resulting magnesium ingots.
