Limonite: Properties and Occurrences Assignment Point

Properties. Limonite is relatively dense with a specific gravity varying from 2.7 to 4.3. The limonite streak on an unglazed porcelain plate is usually brownish, which differentiates it from the mineral hematite, with a red streak, or magnetite, with a black streak. It varies in color from a bright lemony yellow to a drab greyish brown.

Limonite Mining Fundamentals

The limonite streak on an unglazed porcelain plate is usually brownish, which differentiates it from the mineral hematite, with a red streak, or magnetite, with a black streak. Limonite attains magnetic properties when heated, and has an opaque appearance. The hardness of limonite varies from 4 to 5.5. References. Limonite Minerals.net

University of Minnesota’s Mineral Pages: Hematite

With all of hematite’s many varieties, it is natural that some of them can be easily confused with other metallic minerals. All of the hematite varieties though, exhibit the same distinctive red to red-brown streak when scratched across a rough hard surface, which should serve to distinguish hematite from similar-appearing minerals.
