In the mineral processing industry, the energy-efficiency of                    comminution of rocks/ores has not seen any major advances in the last           few decades; the fundamental process is still energy intensive and              extremely indfficient.  In response to this situation, a radically              different and new approach to the problem was concieved and studied in          Phase I.  The approach centers around the concept of hydraulically              applying the input energy directly along grain boundaries,                      microcavities and pores of the material, and generating the high stress         gradients necessary to effect fracture with a minimum of waste.  The            Phase II Program involves the following tasks:  (1) construction of a           laboratory prototype system with automated feedback controls and data           acquisition system, (2) collection of rock/ore samples and measurement          of their physical properties, (3) development of an analytical                  solution/model to simulate the process, and (4) testing of the samples          of the prototype.
