What test would you perform to distinguish hematite form copper how would you carry out this test?
A few things used to identify minerals are streak tests, hardness, cleavage, solubility, magnetic.Streak test: When you scrape a mineral on a streak plate it leaves behind powder of a certain color. Hematite leaves a red streak. I don't know what streak copper has.Hardness test: minerals have different hardness, their ability to be scratched or scratch. this can be determined by seeing if you can scratch a mineral with your finger nail or if the mineral will scratch a piece of glass. I don't know if this test will do much good though in determining copper from hematite.Cleavage: Cleavage in mineralogy refers to when you break a mineral, how it fractures. Does it fracture into cubes, rhombus shapes, conchoidal, etc.Solubility: copper is soluble in acids and forms green-blueish solutions, hematite is insoluble.Magnetic: hematite is sometimes slightly or strongly magnetic. copper is not magneticAfter you test your samples, look up in a book or manual to see which mineral(s) have matching properties.
