2021-9-8 The typical silica and alumina bearing minerals present in iron ores are quartz, kaolinite, gibbsite, diaspore and corundum. Of these it is often observed that quartz is the mean silica bearing mineral and kaolinite and gibbsite are the two-main alumina bearing minerals [7]. Iron ore extraction is mainly performed through open pit

Wet beneficiation of iron ore fines less than 1 mm typically involves a desliming stage ahead of the fine gravity separation such as spirals. The desliming is achieved using a bank of cyclones. The reject ultra-fines emerge in the overflow stream at relatively low pulp density, contain high proportions of low-value slimes, but also well-liberated iron ore ultra-fines below 0.045 mm in size ...

The iron units contained in the tailings can be separated from the siliceous gangue in a second step of the operation (e.g. by agglomeration at a lower pH). These results show that by operating between about pH 8 - 10 the P can be selectively agglomerated from the ore, and the iron can then be recovered from the tailings in a further step.

2016-6-11 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.
