Advances in the mineral processing steps are constant. Crushing develops more efficient particle breaking, avoiding fine particles, and optimizing energy consumption. The liberation step is the grinding process and consumes most of the energy in a mineral processing plant. The liberation size gets smaller every day, and the milling operation ...
