THE HEAVY MINERALS OF FLORIDA BEACH AND DUNE …

The heavy minerals of the Florida region are very sparse in the areas of Pleistocene sands back from the coast, but occur in noteworthy amounts on the beaches now bordering the shore and in the sand dunes along the coast, and some of these form commercial deposits. On the beaches, wave action has locally concentrated the heavy minerals into

Mineral Sands - Community Over Mining

Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.

Mineral Production in Iowa

Iron: Iron ore from the Waukon area in Allamakee County is the only other metallic mineral ever commercially mined in Iowa. The Iron Hill deposit was explored in the 1870's and was first mined in 1899. Operations were suspended in 1901 until the Missouri Iron Company of St. Louis acquired the deposit in 1906, and an ore
