Only 10 operations in 5 states.... Once again, Plenty room for our gear.
Domestic Production and Use: In 2016, 10 operations in five States produced pumice and pumicite. Estimated
production1 was 310,000 tons with an estimated processed value of about $10.2 million, f.o.b. plant. Pumice and
pumicite were mined in Oregon, Idaho, California, New Mexico, and Kansas, in descending order of production. About 50% of mined pumice was used in the production of construction building block and 20% was used for horticultural purposes. The remainder was consumed in abrasives, concrete admixtures and aggregates, and other uses, including absorbent, filtration, laundry stone washing, and road use.
