Magnesium recycling

The comminution of magnesium in the laboratory requires careful planning and strict safety precautions. Due to the high reactivity and fire hazard of fine magnesium dust, the following should be observed:

• Crushing methods are chosen that allow safe handling (e.g. mills in an inert gas environment or cryogenic crushing),
• appropriate safety and dust control systems are implemented,
• all processes are continuously monitored and possible sources of danger (such as sparking, static charge) are consistently minimized.

These measures can significantly reduce the risk, ensuring safe and efficient comminution of magnesium.

• Inert gas atmosphere: To prevent oxidation, it is recommended to carry out the crushing process in an inert gas atmosphere (e.g. argon or nitrogen).
• Explosion-proof devices: The use of equipment specifically designed for handling fine, reactive metal powders minimizes the risk of sparking and static electricity.
• Protective clothing and equipment: Personal protective equipment (PPE) such as safety goggles, anti-static clothing, flame-resistant gloves and, if necessary, a respirator should always be worn.
• Extraction and ventilation systems: Effective extraction and controlled ventilation of the work area are essential to remove released dust and any gases that may be produced.
