recovery. Mineral beneficiation is an energyintensive industry on a global scale. Especially particle size reduction by grinding consumes about 4% of the world's energy. This case study explores an approach to avoid excess use and loss of energy in mineral beneficiation processes. The …

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

1 Over the past 15 years, minetomill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
