Fine copper powder can be prepared using thermal decomposition of copper citrate (can be prepared by mixing dirt cheap citric acid, three equivalents of a base like potassium hydroxide and copper sulphate). I once made pyrophoric (!) copper powder using this technique. There are mentions of preparation of iron powder.
Manufacturing Process of Copper - The Balance
Mar 2, 2017 . Virtually all sulfide-type copper ores, including chalcocite (Cu2S), chalcopyrite (CuFeS2) and covellite (CuS), are treated by smelting. After crushing the ore to a fine powder, it is then concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it.
