Tintic Standard Reduction Mill
Encyclopedia
The Tintic Standard Reduction Mill—also known as the Tintic Mill or Harold Mill—built in 1920, and only operating from 1921 to 1925, is an abandoned refinery
located on the west slope of Warm Springs Mountain near Goshen
, Utah
, in the United States
. Metals processed at the mill included copper
, gold
, silver
, and lead
, all of which were received from another mill
near Eureka, Utah
. The reducing process used was an acid-brine chloridizing and leaching
process which became outdated, leading to the abandonment of the site in 1925. At the mill's highest productivity it processed 200 tons of ore
yearly from the Tintic Mining District.
What remains of the mill are foundations for water tanks, crusher
s, roaster
s, iron boxes, leaching tanks, and drain boxes. The site dominates the surrounding landscape with its size and unique colors and shapes.
It has been speculated that the mill may be the contributor of heavy metal pollution in the Goshen Warm Springs which lie below it.
