The Socorro plant produces crude perlite ore. 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 soil substrates. The medium sizes are typically expanded into aggregate and building products. The finest sizes are most typically used in chemical and industrial filtration as well as lightweight fillers. Furthermore, perlite as an amorphous aluminosilicate, falls in the category of natural pozzolans and when finely ground presents excellent pozzolanic properties that fulfill the ASTM C618-19 specifications. Natural Pozzolans are used as Supplementary Cementitious Materials (SCM) in ready-mix concrete applications, oil well cementing, cement boards production. The dome-shaped perlitic deposit at Socorro where Dicaperl is mining and processing its ore is considered world-class. In the United States, it is surpassed in size only by the No Agua perlite deposit in northern New Mexico, where Dicaperl owns a companion mine. Socorro perlite is shipped all over the United States, Canada, Mexico, and overseas.
