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
Do you mean iron powder mixed with sulphur powder? Fe(s) + S(s) ---> FeS (iron sulfide)
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.
The salt dissolves in the water and the iron does not.
The correct name of the electrode is E8018. E stands for electrode, the 80 stands for 80000 psi minimum as welded tensile strength, the 1 stands for all position, and the 8 is the number associated with the ingredients of the flux, which in this case is low hydrogen and increased amounts of iron powder.
Magnesium is in most airplane and automobile parts.:):):):):):):):)
E 6013 E - Electrode 60- 60000 psi Tensile strength 1 - All position 8 - Basic lime / Iron powder flux
nickel
H2 (g) + FeSO4 (s) hydrogen gas and iron sulphate

E7018 is a shielded metal arc welding (SMAW) electrode. 'E' stands for electrode. '70' stands for 70000 psi minimum as welded tensile strength. '1' designates the position the electrode can be welded in, in this case all positions. '8' classifies that the electrode is a low hydrogen electrode and contains a higher amount of iron powder.
6010 600000 psi, i =all position, 0 = ronze High charged iron electrode, it's about 246 mV
get a magnet that attracts iron
