ZEOLITE DIVISION HIGHLIGHTS
“Zeolite” refers to a group of minerals that are basically hydrated calcium potassium sodium aluminosilicates in which the water is held in cavities in the lattice. The lattices are negatively charged and they loosely hold cations such as calcium, sodium, ammonium, and potassium and also water. The zeolites are also referred to as “molecular sieves”, because the channel ways within the crystalline structure are extremely small and they can be used to separate large molecules from smaller molecules.
BEAR RIVER ZEOLITE CO., INC. (BRZ™)
Bear River Zeolite Company is a wholly owned subsidiary of United States Antimony Corporation. The BRZ™ deposit is located in southeast Idaho, and it is convenient to two railroad lines and major interstate highways.
The deposit is a very thick sedimentary deposit of zeolitized volcanic ash that includes an 800 foot mountain. Zeolite can be sampled over a vertical extent of 800 feet and on more than 700 acres. Despite the apparent huge size of the deposit, the Company claims no reserves.
Mining is performed by stripping a small amount of overburden, drilling and blasting, loading on rock trucks, and hauling to the mill
Crushing to produce coarser products is performed with a jaw crusher, cone crusher, hammer mill, VSI, and numerous screens. Finer products are produced with a Raymond roller mill. Blending, a variety of packaging, and warehousing are available to customers. .
