The bulk of the nickel mined comes from two types of ore deposits: laterites where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate), or. magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8].
Limonite is a mineral that is composed mainly of hydrated iron oxides, typically goethite and/or lepidocrocite, along with other minerals such as magnetite, hematite, and quartz. It is a yellowish-brown to dark brown mineral with a dull or earthy luster and a hardness of 4 to 5.5 on the Mohs scale. Limonite is a secondary mineral that forms from the weathering of other …

Fluorite is no longer mined in the United States due to high excavation costs, and most fluorite is now imported. Before the mines closed, the state of Illinois was the leading producer of fluorite/fluorspar. The state accounted for more than 50% of the total U.S. fluorite production. Can You Find Fluroite in Your Backyard?
Used earlier by the iron and steel industry, limonite and other East Texas iron ores have more recently been mined for use in preparing portland cement, as a weighing agent in well-drilling fluids, and in animal-feed supplements. When iron production virtually ceased in 1910, less than 700,000 long tons of ore had been processed.
