5 Gravity Separation Processes You Need to Know Dense media dressing is mainly determined by the grain density of the ore while the grain size and shape of the ore have little influence on the dense media separation so the separation accuracy is relatively high and the density difference that can be separated is small such as 1g/cm3 the range of the feeding size is large and the
