Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "runofmine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

Niobium processing, preparation of niobium ore for use in various products. Niobium (Nb) has a bodycentred cubic (bcc) crystal structure and a melting point of 2,468 °C (4,474 °F). Of the refractory metals, it has the lowest density and best workability for this reason, niobiumbased alloys are often used in aerospace appliions.
Recent Improvements of Refinement Methods . Improvement of the Traditional Method: Molycorp. The traditional method of extracting pure REEs from mined material is called the solventexchange method, and consists of first crushing the rock into smaller chunks and then grinding it into a fine dust.

The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.
