The Dicalite Burney deposit is one of the premier commercial fresh-water deposits in the world. Its ore reserves are substantial to meet the projected market demands for the future.
Diatomaceous earth, also known as diatomite and DE, is the naturally occurring fossilized remains of diatoms—single-celled aquatic algae.
Dicalite Europe, based at the port of Ghent in Belgium is located in the center of Europe and produces milled, expanded perlite filter aids and fillers. In fact, The Dicalite Management Group, Dicalite Europe division, is the largest producer of perlite filter aids and functional fillers in Europe. Visit Dicalite Europe
Perlite is an essential filtration aid in many industries because of its low density, availability, performance, cost, and limited environmental footprint.
Dicalite’s natural Diatomaceous Earth is mined and processed at our facility in Basalt, NV. Dicalite’s Basalt mine is one our oldest serving mines, dating back to 1926. Currently the Basalt diatomite plant is the fourth oldest continually operated mine in the state of Nevada.
Our natural diatomaceous earth meets the National Organic Program standards and is dried, sized, and sold without further processing.
According to the 2017 USGS Mineral Commodity Summary, there are only two companies mining and operating Vermiculite domestically. Specialty Vermiculite Corporation (SPV) is one of those companies. SPV produces vermiculite concentrate in Enoree, South Carolina.
Vermiculite’s water-wicking, lightweight, and thermal-resistant properties make it ideal for many uses in horticulture, construction, and more.
Socorro Perlite production was the original source of New Mexico perlite, beginning production in 1949. The perlite dome that Dicaperl has developed at Socorro is one of the premier deposits in the world. The various ore products that are sold at Socorro are the result of controlled crushing and sizing to specified grades. The coarser grades of perlite ore are typically used as horticultural additives. The medium sizes are typically expanded into aggregate and building products. And the finest sizes are most typically used in the filtration market.
Perlite is one of nature’s most versatile and efficient minerals. It is formed by molten rock—volcanic glass—processes that trap water into the perlite matrix over geologic time periods. When perlite ore is heated rapidly, the volcanic glass softens, causing the entrapped water molecules to turn to steam and expand the particles, much like popcorn, and it grows up to 20 times its size. These expanded perlite particles are lightweight and insulated glass bubbles that can hold water and air.
