Mg Recycle

Laser refining of magnesium

Applied Physics Letter 2006 Announcement

The most poplar method for magnesium production today is the Pidgeon method. However, this method uses 10 kg of coal to produce 1 kg of magnesium. This does not allow magnesium to be an alternative energy source to coal. Professor Emeritus of Tokyo Institute of Technology Yabe proposed to convert natural energy into a laser for refining, achieving the same purity with much higher efficiency. Here's why the laser method is so good.

​Experiment to regenerate magnesium by laser

Some people may think that using a laser for refining is too expensive. Actually, it is not expensive even at present. The price of semiconductor lasers will drop dramatically if they are mass-produced, so equipment costs will drop even more in the future.
