Open Access Recovery Improvement of Fine Iron Ore Particles

Earlier work with iron ore and iron ore fine/slime indi-cates that beneficiation of iron ore and fine/slime containing very low iron and high alumina and silica is quite difficult. Also, it is equally difficult to know the characteristic proper-ties of the particles where most of the population is below 50 micron.
