1. take 6 coins at random and put three in each side of balance. if the heavy coin is among them you will know on which side it is.
2. now take any two of those three and weigh again. if they are balanced the coin in question is the remaining one.
now if on first try you get equal weight on both sides than the heavy coin is in the remaining three.
so repeat the process no.2 and you will get your coin.
hope i have answered rightly
