banded iron experiment

[Jazz]

hi
I need instructions for the "banded iron experiment" something with iron sulfate and manganese dioxide .....????

[lada]

Need more info!!!

Yes, indeed. Need more input. Is this some form of oxidation or precipitation experiment? Perhaps geology?

Banded Iron is a sedimentary rock formation, composed of alternating layers of iron oxides and shale or chert (both iron poor sedimentary rocks).

If only I had more info, sorry
It is for EE year 12, rock formation ?????
need experiment for it. I had it; but washed my USB one too many times )
all I can remeber is these few chemicals

I have looked in our Enviromental Science text books but couldn't find anything. The EES teacher could provide no information either.

However I couldn't resist posting this picture of "banded iron" that I took at Broken Hill
