T. Allan Comp, IIAER UT-12 (page 1) '4 h U P UTAH t TINTIC STANDARD REDUCTION MILL 2S The Tintic Standard Mining Company was incorporated by Emil J. Raddatz in October of John Bestlemyer, Greely Snyder, and George Horton, Sr. all owned mining claims that became part of Tintic Standard and a large part of the money for the shares of stock came from people in Milwaukee. The first commercial ore was encountered in and by big scale production had 2 begun. Established as an important silver producer in the Tintic district, during and Raddatz under- took the construction of a small ore mill to be known as the Tintic Standard Reduction Mill. The mill was built on a hillside near Warm Springs, two miles east of Goshen Township, Utah. It was designed and constructed under the direction of W. C.

Madge who con- sulted with Theodore P. Holt and George C. Dern, developers of the well-known Holt-Dern roaster used in numerous smelters. Built at a cost of the mill was reported to be 80 per cent complete by the end of 1 Raymond Duane Steel, Goshen Valley History Part IV p. 211 2 Salt Lake Mining Review, October 15, 192 7. ~2~ HAER UT-12 despite "adverse labor conditions."3 Operations initially got underway in February of and by April the mill was "working at full capacity in every department."4 The mill initially processed 140 tons per day, but by March it was treating between 160 and 180 tons per day. After two furnaces for roasting sulphide ores were added during capacity was expected to increase to 200 tons per day, or somewhat less than half of the daily production of the mine.

Metallurgical research work by the company devel- oped a method of recovering lead from the ore and a lead unit was added to the mill during the first half of The mill, however, did not last long. It soon developed that the mine in the condition it then was, could not supply an adequate tonage of ore of the grade and composition for which the plant was designed. The ore did not return as much net profit as if it had been sent to the smelter.^ Operations at the mill, which worked around the clock with about 25 men on each shift, were shut down in the fall of The mine continued to operate successfully, but no mention of the mill is made in the company reports after 3 ...

Harry P. Allen was superintendent of the mill and Lou Whimpey worked as foreman during its five years of operation. A small town, named after Raddatz's son Harold, grew up while the mill was in operation. It consisted of a boarding and lodging house, a commissary, and three of four houses for the mill officials. In addition, these few years were "almost a boom period" for Goshen, since the town was located between the mine and the mill.

The Tintic Standard Reduction Mill was the only use of the antiquated Augustin process in the United States during the early An acid-brine chloridising and leaching mill, ore was first roasted with salt, then leached in a strong brine solution, then precipated with copper. Each batch required 140 hours to run, but re- covery rates were fairly high. In the mill recovered 88% of the silver, 60% of the copper, 32% of the lead, and 7% of the gold held in the ore.12 Except for its "unique" process perhaps antiquated is a better word this author can attach no "significance" to the Tintic Standard Reduction Mill.

None of the national mining journals consulted carried anything of significance, but one discussion of milling practice at the Tintic Standard Reduction Mill was encountered and is included with the report.
