| Outline of Final Research Achievements |
The objective of this study is to develop the high efficiency crushing method for recovering rare metal utilizing the discharge crushing and the distribution caused by the shock wave focusing using the reflector. The optimum geometry of reflector attachable to the electrode of discharge crushing device casing the distribution by the shock wave focusing was researched by the numerical simulation. The mechanism of liberation of rare metal block from the simulated capacitor model induced by the underwater electrical discharge, the underwater explosion, was clarified by the visualization. The effect of number of discharge times on the particle size distribution of resin lump by the discharge crushing was investigated. The results of these researches indicated the possibility of establishment of high efficiency crushing method using the discharge crushing and the distribution by the shock wave focusing with the optimized reflector.
