Little Cottonwood Creek (Salt Lake County, Utah) confluence with the Jordan River. The stream provides electrical power generation for Murray City. The first legitimate mining operation in Little Cottonwood Canyon was established in 1865. The ore deposits in Little Cottonwood Canyon yielded principally silver and lead with some copper, gold, and zinc. These ore deposits were formed mainly in shale, limestone, and dolomite. Galena or lead sulfide was the common primary lead mineral of the area. Argentite was found in most of the primary ores and was probably an abundant primary silver mineral. Ore production varied with time because of the nature of the deposits and the
Heavy mineral sands ore deposits deposit is usually low. Within the 21st century, the lowest cut-off grades of heavy minerals, as a total heavy mineral (THM) concentrate from the bulk sand, in most ore deposits of this type is around 1% heavy minerals, although several are higher grade. Of this total heavy mineral concentrate (THM), the components are typically Generally, as zircon is the most valuable component and a critical ore component, high-zircon sands are the most valuable. Thereafter, rutile, leucoxene and then ilmenite in terms of value given to the ore. As a generality, typically the valuable components of the THM concentrate rarely exceed
