Abstract: The invention provides a method for the recovery of a metal-containing product (MProd) comprising: providing a composite material comprising a matrix of oxidised reductant (Ro), a product metal (MP) dispersed in the matrix of oxidised reductant (Ro), and one or more metal compounds (MPCR) of the product metal (MP) in one or more oxidation states dispersed in the matrix of oxidised reductant (Ro); and treating the composite material to at least partially remove the one or more metal compounds (MPCR) from the matrix of oxidised reductant (Ro) to form the metal-containing product (MProd).

Abstract: An impact fatigue device includes a striker rod assembly configured to reciprocally move between an upstream position and a downstream position. The striker rod assembly includes a striker rod slidingly mounted on a support member and a trigger located upstream of the striker rod and adapted to move downstream to engage the striker rod and propel the striker rod downstream. An actuator assembly is located upstream of the striker rod assembly. The actuator assembly is configured to releasably engage the trigger and to translate the trigger upstream. A reset mechanism is configured to releasably engage the striker rod and to move the striker rod from the downstream position to the upstream position. A method of operating the impact fatigue device is also disclosed.
