SECTION 5: PRODUCTION METHODS

Method 1: Electrolytic Method (Most Common)

• Process: Magnesium chloride (MgCl₂) → Electrolysis → Pure magnesium → Casting

• Reaction: MgCl₂ (molten) → Mg + Cl₂ (electrolysis)

• Description: Magnesium chloride is obtained from seawater or brines; Electrolyzed in molten state to produce pure magnesium; Most common industrial production method; Produces high-purity magnesium (99.9%+)

Method 2: Pidgeon Process (Thermal Reduction)

• Reaction: 2MgO + Si → 2Mg + SiO₂ (at high temperature under vacuum)

• Description: Dolomite (CaMg(CO₃)₂) is calcined to MgO; Reduced with ferrosilicon under vacuum at high temperature; Produces magnesium vapor which is condensed; Common in China

Method 3: Magnetherm Process

• Reaction: MgO + C + Cl₂ → MgCl₂ + CO (at high temperature)

• Description: Magnesium oxide is chlorinated to produce magnesium chloride; Electrolyzed to produce magnesium

Method 4: Recycling (Scrap Melting)

• Process: Magnesium scrap → Sorting → Melting → Refining → Alloy → Casting

• Description: Magnesium scrap is collected, sorted, and melted; Purified by refining; Composition adjusted; Sustainable production

SECTION 20: CRITICAL WARNINGS AND BEST PRACTICES

CRITICAL WARNINGS:

• Flammable solid (H228). Burns with bright white flame. Keep away from heat and ignition sources.

• Reacts with water releasing flammable gas (H261). Contact with water produces hydrogen gas (explosive). DO NOT USE WATER for firefighting.

• May cause respiratory irritation (H335). Avoid inhalation of dust/fumes.

• Highly reactive. Reacts with acids vigorously; Reacts with halogens.

• Metal fume fever: Inhalation of high concentrations of magnesium fumes may cause fever, chills, and nausea.

• Incompatibilities: Keep away from water, moisture, acids, oxidizing agents, and halogens.

• Hygiene Requirement: Wash hands thoroughly after handling.

BEST PRACTICE RECOMMENDATIONS:

• Automotive Applications: Use magnesium alloys for lightweight components; Reduces vehicle weight by up to 30%; Improves fuel efficiency and reduces emissions; Excellent vibration damping for improved ride comfort.

• Aerospace Applications: Use for high-strength, lightweight components; Critical for weight reduction in aircraft and spacecraft; High strength-to-weight ratio; Good machinability for complex geometries.

• Chemical Applications: Use as reducing agent and Grignard reagent; Essential for organic synthesis; Titanium and uranium production; Chemical reactions.

• Casting and Machining: Easy to cast and machine; Suitable for die casting, sand casting, and permanent mold casting; Good dimensional stability.

• Handling: Use in well-ventilated areas; Avoid dust generation; Wear protective gloves, safety goggles, and appropriate respiratory protection; Keep away from heat and ignition sources.

• Personal Protective Equipment: Safety goggles, protective clothing, protective gloves (nitrile, neoprene), NIOSH-approved dust mask (if dust).

• Hygiene: Wash hands thoroughly after handling; Do not eat, drink, or smoke when using.

• Storage: Store in cool, dry, well-ventilated area; Protect from moisture; Keep away from acids and oxidizing agents; Store away from heat sources.

• Spill Response: Avoid dust generation; Vacuum or sweep; Place in closed containers; Do not allow to enter drains or waterways; Keep away from water.

• Disposal: Dispose of in accordance with local, regional, and national regulations; Magnesium is recyclable; Recycle where possible.

SPECIAL NOTE ON MAGNESIUM FIRE:

Magnesium fires require special attention:

• Characteristic: Burns with extremely bright white flame; Very high temperature (can reach 3,000°C)

• Extinguishing: DO NOT USE WATER (reacts violently, produces hydrogen gas); Use Class D dry powder extinguisher; Use dry sand or graphite powder

• Precaution: Do not attempt to extinguish with CO₂ or foam (ineffective)

• Safety: Evacuate area; Use full PPE with SCBA
