Recycling of materials: magnesium
Recycling of materials became increasingly important during the last decades of the twentieth century, and continues to have a significant influence on chemical industries.
A large fraction of the total Mg consumed is in the form of Al/Mg alloys (see Figure 1.1), and recycling of Al cans necessarily means recovery of Mg. The graph below shows the variation in total consumption of primary Mg in the US from 1960 to 2000, and the increasing trend towards recovering the metal.
