how to differinciate between earth iron ore and stony iron meteorites

Astronomy Lesson 2: Meteorites, Shooting Stars, and Comets ...

Iron ore minerals, such as hematite and magnetite, can also be confused with meteorites, but a simple laboratory test for nickel will determine their true nature. Earth rocks have either very small or very large amounts of nickel, but in meteorites the nickel content falls within a very specific range.
