Overview

At the mouth of Little Cottonwood Canyon, east of the town of Sandy City, in an unincorporated area of Salt Lake County, Utah, in addition to the granite quarries, there were at least three smelters. Today, the area includes the remains of three: the Flagstaff, the Davenport, and the McKay. Remnants of two smelters (Davenport and McKay) are visible in the area of 3500 E. Little Cottonwood Lane (about 9800 South). The Flagstaff smelter was located less than a quarter mile to the north, near 9500 South Wasatch Boulevard, on the north side of Little Cottonwood Creek.

In Big Cottonwood Canyon itself, on the Silver Fork of Big Cottonwood Creek, on August 3, 1871, ground was broken for a new Gerrish-patent smelting furnace. The new smelter was owned by the Chicago Mining Bureau and was the first furnace in Big Cottonwood Canyon. ("The Year Of 1871", Our Pioneer Heritage, Volume 15, 1972, p. 56)

On September 6, 1871, Utah Southern reached Sandy. Two smelters were built at Sandy, near the railroad tracks; one of them was the Saturn Silver Smelter, the largest in the territory, with a capacity of 50 tons per day. (Reeder, pages 116, 117)

The original Wasatch and Jordan Valley Railroad was incorporated October 24, 1872 to build a line from Sandy to the mines located in Little Cottonwood canyon. Construction started in November 1872 over a grade previously started by Utah Southern in summer 1872 and rails were laid five miles to the Davenport smelter and the granite quarries at the mouth of the canyon by April 1873. The line was completed to its terminal at Fairfield Flats at the mouth of Little Cottonwood Canyon by September 1873. Scofield took control of the railroad in June 1875 and completed an eight-mile mule tramway to Alta by September 1875. (Reeder, pp. 170-189)

Davenport Smelter

From "Scorecard" website:

The Davenport and Flagstaff Smelters site is located east of the Town of Sandy City, Salt Lake County, Utah at the mouth of Little Cottonwood Canyon. A number of smelters operated in Little Cottonwood Canyon during the 1870s. Three of these smelters were located at the mouth of the canyon, the Davenport Smelter south of Little Cottonwood Creek, the Flagstaff Smelter on the north bank of Little Cottonwood Creek, and the McKay Smelter located immediately adjacent to the former Davenport Smelter site. The small town of Granite was built near the smelters and during its heyday (1872-1874) consisted of about 50 buildings serving the workmen at the smelters and the teamsters who hauled the ore from the mines. When the smelters closed, the town was abandoned. The Davenport Smelter was a lead and silver smelter located on the south side of Little Cottonwood Creek just west of the mouth of Little Cottonwood Canyon. The smelter was located on the property purchased by the Davenport Mining Company from S. J. Despain on March 7, 1873. Ores smelted at the site were mined primarily from the Davenport and Matilda Mines located in Little Cottonwood Canyon and were hauled by wagon from the mines to the Davenport Smelter. The ores contained more than sixty to seventy ounces of silver per ton and were by volume between 12 and 18 percent lead. The smelter operated from 1872 until 1875.

The Davenport Smelter site was listed on the EPA's "Superfund" list in April 1992 after a study of historic smelters in the Salt Lake Valley conducted by the state of Utah. The smelter site is west of the mouth of Little Cottonwood Canyon, south of Little Cottonwood Creek and north of Little Cottonwood Road in an area that was known as the Beaver Pond Springs. (source)

Mingo Smelter

From Daughters of Utah Pioneers Marker 470, erected in 1993:

The Mingo Smelter was the largest single producer in Utah of metals such as gold, silver, and lead. When it began in 1873, it was known as the Mountain Chief Smelter and was renamed the Mingo smelter in 1876 when it was expanded. By 1881 it produced 19,000,000 pounds of unrefined metal which was shipped to Pennsylvania. The rich ores came from Little Cottonwood Canyon, Bingham Canyon and Lark and provided work for 500 to 1,200 men. Power for the smelter was provided by water traveling through a network of canals to Allsop's Pond on the south side of Locust Street. From there, it was channeled through wooden pipes to Mingo. In 1877 the plant consisted of Blake crusher, one pair of Cornish rolls, two reverberatory furnaces for ore, matte, and flue dust, three blast furnaces, two boilers, three blowers, and one 35 horsepower horizontal engine. The iron flux came from the Tintic District, the limestone was bought in Salt Lake City, and the fuel used was coke. Using all four of its furnaces, the Mingo Smelter could produce enough metal to fill sixteen railroad cars each week. It was destroyed by fire in 1887 and was rebuilt in 1888. The Mingo closed in April 1901 when the ores were depleted. This was one of the most successful of the old smelters that operated in Utah.
