    Apr 29, 2018· Flotation could not operate, however, without effective comminution, which has had to evolve rapidly with the need to grind ores finer, and to do so with the minimum expenditure of energy. Worldwide the mining industry consumes around 2% of all electrical energy, and comminution is the major consumer, so great efforts are now made to reduce ...
