Abstract

Pyrite FeS2 chemical formula is part of iron ore abundantly found in Madagascar. It also presents
many application that a few of them are the goal of this work. The synthesis of ferric sulfate from pyrite is
a simple and convenient method (cost, time, etc.) while that of ferric oxide, to serve the completion of the
synthesis of ferrate, is a bit complicated. The synthesis of ferrate alkaline VI is an easy process, but
requires a lot of control. It shows positive results only in a temperature above 800 °C over 3 hours time.
Below this temperature we got another product with low oxidative we named ferrate IV or V. The
application of these reagents in water treatment reveals the advantage of ferrate which is at the same time
coagulant and disinfectant and ferric sulfate is cationic coagulant and a flocculent proven by its power to
form large flocks.
