What is it?

So yesterday we featured the vitamin C so today we’d better follow it up with a mineral. We’re told to maximise our vitamins and minerals in our diets – and generally the ‘mineral’ part refers to metal atoms that we get though eating things like green veg and sometimes even rubbed of our cutlery. But for, for many reason, we may sometimes be deficient in a mineral and need to take a supplement. For instance iron supplements (which are taken when diagnosed with anaemia) the iron comes within an iron sulphate compound – often a hydrate. There are a few iron sulfate hydrate minerals that are found in nature, and similar to source of iron found in the supplements we take. Today’s structure is of melanterite, which is a iron sulfate heptahydrate (seven water molecules) a rare mineral found in Canada.

Where did the structure come from?

The structure of Melanterite can be found in the American Mineralogical database.
