Hydrogen evolution on quarter-core cathodes from one weathered nickel-sulfide hole
A research poster from the School of Underlying Conditions saws quarter-core from fourteen 1 m intervals of one weathered nickel-sulfide exploration hole into discs and runs them as hydrogen-evolution cathodes in acid. As cut, the discs rank by weathering zone, with transition-zone discs 79 mV ahead of fresh sulfide; after 48 hours of cathodic conditioning that gap closes to 10 mV, and across the eleven sulfide-bearing intervals the overpotential follows nickel grade instead.
