Silicon Metal – AMG Corporate
In aluminum foundries, silicon is an important alloying element. With further purification processes, metallurgical silicon can be converted to high purity silicon, which is the basis for semiconductors or solar cells. Microsilica is used in cement for building materials and as an additive to ceramics and refractory products.

Metallurgical Coal – Ram River Coal Corp.
Metallurgical coal is more scarce and valuable than thermal coal, so in practice metallurgical coal is rarely used to generate electricity. Metallurgical coal is also common-ly referred to as coking coal. Coking coal has physical properties that when heated cause it to soften, liquefy and then resolidify into a harder substance known as coke.
