Show HALLOYSITE CLAY: Produced by Filtrol Corporation from the Dragon Consolidated mine, Tintic district, and processed at the company's Salt Lake City plant for use as a catalyst in oil refining in the Salt Lake area and on the Pa cific Coast. Input capacity of the plant is about 60,000-70,000 tons of clay per year. LIME AND LIMESTONE: Most of the crushed and pulverized limestone used in Salt Lake County is imported from Tooele County quarries. Salt Lake County is the state's biggest producer of lime. The largest plant is a part of Kennecott Copper Corporation's Utah Copper Division operations. Crushed limestone from Utah Lime Division of the Flintkote Co., which operates in Tooele County, is hydrated to milk of lime in the Kennecott plant and consumed by the company in the treatment of copper ore. The company also sells small quantities of quicklime to other consumers. Kennecott's output usually accounts for about two-thirds of Utah's lime production. Utah-Idaho Sugar Co. uses about 5,000 tons of limestone from Juab County each year for manufacturing quicklime at its Salt Lake City sugar refinery. The quicklime is used in the sugar refining process. OIL: While Salt Lake City is widely known as an oil refining center, only one refinery actually operates in Salt Lake County . The others are all north of the Davis County line. The American Oil Co.'s plant refines oil piped from the Rangely Field in Colorado and from the Uinta Basin in eastern Utah. This is one of the county's major industries. PERLITE: In the 1950s there were three perlite expanding plants in Salt Lake City. One burned down and one closed for economic reasons. Acme Lite-Wate Products, Inc. is the only firm in the county with expanding fa cilities. It uses perlite from the North Pearl Queen Quarry of Henry Schoo in Beaver County and from Nevada properties. The expanded product goes into the manufacturing of building plaster, concrete aggregates and soil conditioners. Vermiculite Intermountain uses perlite from Beaver County in the making of insulating materials. PHOSPHATE ROCK: Processing of phosphate rock, once chiefly from Wyoming, but with a steadily increasing volume from Utah's deposits, is one of Salt Lake County 's new industries. Stauffer Chemical Co.'s Fertilizer Division is operating a large plant at Garfield, with a production capacity in excess of 200,000 tons per year of treble superphosphates, phosphoric acids, ammoniated phosphates and other products. A large percentage of the ammonia from U. S. $tee\'s nitrogen plant in Utah County and the sulphuric acid produced at Garfield is consumed by Stauffer. Phosphate rock for the operation comes from Rich County (via a W yo ming processing plant) and Uintah County , with most of it being furnished by the Vernal operation of San Francisco Chemical Co. PUMICE: This mineral is imported from central Utah counties, from Idaho and other states for use as a lightweight aggregate by Buehner Block Co., Otto Buehner Concrete Products Co., Prince Block Co. and Rockymountain Refractories. RESINS: Fossil resins processed at Bauer, Tooele County, by Combined Metals Reduction Co. from waste coa l fin es from U. S. Fuel Co.'s Hiawatha , Carbon County mines, are sometimes used in small volume for paint manufacture by Bennetts. SHALE: Expanded shale quarried and processed in Summit County has found a large market in Salt Lake County as a lightweight aggregate for manfacture of concrete bricks, blocks, etc. Some of the major users are Prince Block Co., Utah Concrete Pipe Co. and Buehner Block Co. This mineral has largely replaced pumice for these uses. STONE: Some of the major importers of stone in Salt Lake County are: National Stone Suppliers-Black marble, pink travertine, cream travertine and snuff-colored onyx from a deposit at Pelican Point, Utah County; green onyx, white marble and brown-and-white marble from a quarry five miles west of 68 Nephi, Juab County; black obsidian fr om a p~'operty 25 miles northeas~ of Calleo, in Tooele County; white dolomite and white quartz from a depOSit 16 mlles west of Wendover, in Nevada; pink and cream combination marble from Low, Tooele County; buff jasper and red jasper from a qu arry west of Al~me , Utah County; green marble and yellow marble from Table Top Mounta1O , Tooele County; quartzite in gray, green and brown-and-green from Park Valley deposits in Box Elder County, and sandstone (picture rock) and brown marble from the Vernon area, Tooele County.
