Low-inductance decoupling capacitor for the thermal conduction modules of the IBM Enterprise System/9000 processors

There is provided a process for recovery of metal values from an ore body containing sulfide minerals. The ore body is fractured for increasing its permeability. The fractured ore body is then roasted in situ to increase the permeability and porosity of ore body to liquid leach solutions. The roasted sulfide minerals in the ore body are thereafter contacted with a leach solution to extract metal values therefrom and the extracted metal values are recovered.
