Abstract
This study explained that the used collector type and the Flotation
Procedure have apparent effect on concentration procedure, the results explained
that the used of these collectors lead to occuring of reversed anionic silica flotation
and on using the formic acid it has been noted that the Iron grade increases when
the collector weight reaches to 64% It adding 0.5 gm of the acid. and when acetic
acid was used there is an increasing in Iron grade with increasing of acetic percent
which reaches to 76% inadding 0.3 gm of the acid but on the pH=11 with(0.3) gm
of the same acid (acetic acid) the Iron grade increases to 89% and in using streaic
acid it has been noted that the Iron grade that goted becomes constant which is
about 65% so from these results it had been noted that the acetic acid gives the best
results where it had reached to 89% of Iron grade on adding 0.3 gm of this acid on
pH=11
