Pellet 

a piece of ore that is obtained from fine, dustlike ore or from finely ground concentrates. Pellets are very firm spherical lumps that range in diameter from 2–3 mm to 30 mm; their diameter usually is between 10 and 15 mm.

Iron ore pellets are used primarily in blast-furnace smelting. Pellets are capable of being transported and stored for long periods without significant destruction or formation of fines. They can be fluxed or nonfluxed, depending on whether or not fluxes are added. Iron ore pellets in which up to 95 percent of the iron oxide is reduced to iron are called metallized pellets; they are used primarily in electric steel smelting furnaces to obtain high-quality steel.
