Metabolism of Iron in Human Body (With Diagram)

In anaemic cases, after a single dose of iron, a rise of serum iron takes place in 30 minutes, reaching its maximum in 3-5 hours (0.35 mgm%, compared to normal value, 0.10 mgm %) and returns to normal in about 12 hours. Maximum absorption is com­pleted in 18 hours. [In normal animals little iron needs to be absorbed, because very little is excreted. The body observes a rigorous principle of ...

2017-10-23  The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).
