The slow cooling allows mineral grains to grow and to rise if they are less dense than the magmatic liquid or to sink if they are more dense than the liquid. The dense ore minerals collect in layers on the bottom of the intrusion. Essentially, all of the world's chromium ores and some platinum, nickel, and copper ores formed in this fashion.
