Some important properties of feldspar is the alumina and alkali content. Thus they have many applications in the paint, glass, and ceramic industries.
Desalination requires a lot of contaminants to be removed for it to be a viable process. Anthracite and process expanded clay can provide effective, long-term filtration solutions.
Using anthracite and garnet as solvent extraction filter media enhances the solvent extraction-electrowinning process for extracting metals from their ores.
