Rare Earth Silicon And Magnesium Production Process
How Cerium and Lanthanum as Coproducts Promote Stable Rare Earth …
The largest outputs of rare earth mining are the low-value byproducts cerium and lanthanum, which burden rare earth supply chains because they must be separated from more desirable rare earths used in magnet production. Promoting demand for cerium and lanthanum can potentially diversify the economics of rare earth mining and improve supply chain stability …

The role and significance of Magnesium in modern day
The REE (rare earth elements) improve high thermal strength, corrosion and creep resistance in magnesium. The freezing range of magnesium alloys is also reduced by rare earth elements [30]. The anti-corrosion property of Mg alloys (magnesium alloys) is reduced if the silicon is added along with iron.
