Iron powder will not dissolve in water. It remains as solid particles suspended in water, forming a mixture known as a suspension.
When fine iron powder is mixed with water, the iron does not dissolve; instead, it typically remains suspended as fine particles. Over time, the iron can oxidize, especially if oxygen is present, leading to the formation of iron oxide (rust) if the mixture is left exposed to air. If the mixture is stirred or agitated, the fine particles may temporarily disperse, but they will eventually settle out due to gravity. Overall, the mixture results in a suspension rather than a solution.
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.
Iron is magnetic but copper isn't. So I guess iron powder is magnetic while copper powder isn't.:)
Iron slowly oxidizes in contact with water to form Fe2O3 This is a red powder.

When iron powder and salt are added to water, the iron powder will react with the water to produce iron oxide (rust), hydrogen gas, and heat. The salt will dissolve in the water. This reaction is a chemical change, resulting in a mixture of iron oxide, hydrogen gas, salt solution, and any unreacted iron powder.
You need really fine iron powder; a fine file and somthing out of iron you can file. Then a liquid to keep the iron in suspension; it should dry (evaporate) but not too quickly- water will work if you use your ink right away- if you wait the iron will rust and rust is not as magnetic as pure iron...
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.

Samples of the rock could be crushed to a fine powder, then separated by magnets to determine the relative percentage of iron.
That depends on how fine the powder is. if it is like sand, it probably wont burn that easily, but if it is as fine as flour, then it will burst into flames in 1 second

Sulfur is a fine powder that is light yellow in color; iron filings are metallic. A mixture would be just that: a light yellow powder intersperced with metallic particles.
Lustrous metallic with a grayish tinge.Source: Wikipediathe apperance is the uses of it so theres lots of things people use iron like Wrought Iron gates, Iron wheel, Iron pot ect.ect.
find a cyclops takes its eye and grind it into a fine powder and sprinkle that onto an iron helmet
