how can we extract minerals from spinach?

Answer 1

Sorry, you cannot extract minerals from spinach. Minerals by definitions are inorganic natural substances and are usually poly-elemental, if i may use the term to explain you. All you can do is extract its pulp and juice and separate out different constituents as compounds. The iron available in spinach would not come out as any iron mineral like magnetite, hematite etc.Most of the iron in the extract would be as hydroxide and/or organo--metallic compounds only. For that matter you cannot extract iron mineral from blood.
