Ironsand Wikipedia

Ironsand is found worldwide. Although the iron mineral composition of the ironsand is mostly magnetite, the sand is usually mixed with other types of sand that washes downriver or ashore from mountainous or underwater deposits. The exact composition of the sand mixture may vary drastically even in the same geographic region. In some areas the sand may contain mostly quartz, while in others the sand may be made primarily from volcanic rock such as basalt, depending on the types of minerals along the water's p

Iron mining in the United States Wikipedia

Iron mining in the United States produced 48 million metric tons of iron ore in 2019. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah.Most of the iron ore was mined in northern Minnesota's Mesabi Range.

Magnetite Wikipedia

Magnetite-rich sand dunes are found in southern Peru. In 2005, an exploration company, Cardero Resources, discovered a vast deposit of magnetite-bearing sand dunes in Peru. The dune field covers 250 square kilometers (100 sq mi), with the highest dune at over 2,000 meters (6,560 ft) above the desert floor. The sand contains 10% magnetite.

Geology of Great Sand Dunes National Park and Preserve

Mining ended by 1938, but some prospecting (collection and assay of dune sand samples for gold content) continued to 1941. The major detriment was the low gold concentration. Another, more recent attempt to retrieve placer gold in the region occurred in 1980 at some unknown site on Medano Creek, most likely inside the Rio Grande National Forest.
