Environmental remarks 44% of the world production of magnesium comes from the US. Another 30% of the world production is won in the CIS. There are two types of technology for the refinery of magnesium: the Pidgeon process (smelting under vacuum) and the (electr.) Magnetherm process. The average energy requirement of the winning and refinery process is high. The world reycling percentage is 21%. The data is the world average for 1993.
