Standard pellets generally require less processing, are normally the least costly pellets to produce and are called "standard" because no ground fluxstone (i.e., limestone, dolomite, etc.) is added to the iron ore concentrate before turning the concentrates into pellets. In the case of fluxed pellets, a fluxstone is added to the concentrate ...

Fluxed pellets containing 10% and 20% limestone were produced in a laboratory balling drum. It was found that the pelletization kinetics were sensitive to the water content of the pellets. The moisture content of iron ore fluxed pellets was calculated proportionally according to the amount of water required by pure iron ore and pure limestone ...
