- New Mineral Grinding Techniques
consist of size reduction (or comminution) by crushing and grinding for the liberation of minerals, separation of mineral particles by va rious principles and a number of operations associated with them. However, most of the processes are basically physical (or mechanical), even if chemical effects may play important roles.
