Formation of the Beach Iron Sand Deposit (4 shots)

Many countries now exercise environmental control to reduce pollution & to safeguard ecological balance.
Application of Iron Concentrate
Most of the iron concentrate selling in current market is produced from the lean iron ore derived from
BIF mines, processed and enriched from crushing, grinding and beneficiation (magnetic or gravity separation, or flotation); possessing the characteristics of high Fe content and little impurities.
The iron conc in this project, is
