    Abstract: The present invention is directed to a precious metal recovery process in which basic ferric sulphates and/or jarosites are controlled by a number of mechanisms, including control of the oxidation reaction conditions in the first autoclave compartment, hot curing of the autoclave discharge slurry, and/or contacting of the autoclave feed slurry with the hot cured discharge liquid. Through curing, reactive iron-containing precipitate, such as basic iron sulphate, is allowed to react with acid to form a dissolved iron-containing species, such as ferric sulphate.

    Abstract: A plasma-hydraulic excavation system suitable for use in connection with mining operations is provided. According to the system, one or more groups of plasma-hydraulic projectors that include a reflector and a pair of electrodes are used to break an area of rock. The projectors include a connection box within which high voltage connections between the electrodes of the projector and a power supply cable may be made. Groups of projectors and supporting componentry may be housed within a common frame, to form an excavation module. Electrode insulators interconnected to the projector reflector in compression are also disclosed. A trigger circuit providing a voltage transformer for each projector in a group of projectors is utilized in connection with a series connected current source circuit to provide for the ignition of the projectors. According to an embodiment of the invention, multiple groups of projectors may be operated using a single current control switch.
