Specialized Industrial Minerals

GFI is a leader in the creation of optimized raw feed mixes and raw materials for cement kilns. GFI operates a Diatomaceous earth mine delivering thousands of tons of DE to cement plants across US southwest. GFI's DE is used to create Pozzolan cement extenders for Type 1P portland cement. Locally recycled industrial sands and filter cakes are gathered through recycling and beneficial use programs. GFI combines these ingredients together in specific proportions to create raw materials that can be tailored to a cement kiln's individual needs for optimal cement kiln performance.

GFI supplies high quality iron ore and alumina material to the cement and steel manufacturing industries.
