    The separation process is particularly difficult due to the usually low quantity of gold relative to waste. Common gold grades are in the same magnitude as about 5 g/t, or 0.000005% gold content by weight. This means that upgrading the concentration by a factor of 3000 to 4000 is commonly required to achieve commercial ore (Marsden amp House, 2009).
