find iron ore, and crush or file down then package and use
Iron powder is not soluble in water.
Iron is magnetic but copper isn't. So I guess iron powder is magnetic while copper powder isn't.:)
you get magnesium oxide + iron
get a magnet that attracts iron
no
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
Use a magnet to remove the iron filings. Filter the remainder to separate the insoluble chalk powder from the water. Wash and dry the iron filings as they will be contaminated. Dry the chalk powder to remove traces of water.
Do you mean iron powder mixed with sulphur powder? Fe(s) + S(s) ---> FeS (iron sulfide)
You get iron sulphide.
A magnet will attract the iron leaving the coffee behind. It is also possible to separate them by flotation on water; add some detergent to the water to break the surface tension so the iron powder can sink while the coffee powder floats.
