Abstract: A metal-dissolving apparatus and process is disclosed. The apparatus comprises a reactor, a metal inlet for receiving a metal-containing substance, a solution inlet for receiving a metal-dissolving solution, a solution outlet for providing the metal-dissolving solution comprising dissolved metals. The apparatus comprises a length and a height, the height being less than the length. The process comprises providing a metal-dissolving solution into a first location of a reactor comprising metal-containing substances, flowing the metal-dissolving solution through the reactor, dissolving metal from the metal-containing substances into the metal-dissolving solution, and discharging the metal-dissolving solution from the reactor.

Abstract: An electronic device, and a magnetic energy harvesting device and method of harvesting magnetic energy, for electric metallurgical furnaces and similar environments. The device comprises a conductor which is configured to become induced with electricity in response to a time-varying magnetic field. The field may be irregular, such as near a metallurgical furnace or a similar environment. The electronic device may be a transmitter in a metallurgical electric furnace. The transmitter may be connected to an environment sensor. The electronic device may be powered by the magnetic energy harvesting device. The magnetic energy harvesting device may a wire loop or a coil. The method comprises inductively harvesting energy from magnetic field fluctuations caused by a metallurgical furnace or a similar environment to wirelessly power the electronic device.

Abstract: A gate, leaf, and method for controlling water levels in a body of water. The gate comprises a moveable barrier (which may be a leaf), a restoring device such as a spring, and a profile. The barrier automatically opens or closes an amount to allow less or more water through as a result of changes in the water pressure in the upstream body of water. This helps maintain a water level in the upstream body of water. The profile disturbs the flow of water through the gate to influence the water pressure on the barrier. The profile may help provide a more linear curve for the water moment on the barrier across the range of barrier positions. A more linear curve for the water moment may help maintain equilibrium with the restoring moment across the range of barrier positions. The method comprises disturbing the flow of water over a barrier to redistribute the pressures of the water on the barrier.

Abstract: A highly flexible sealing arrangement designed to seal high-temperature furnace ports, particularly the electrode port of an electric furnace. The seal comprises an annular support member fixed to a flexible sealing member and employs the use of a garter spring to uniformly apply the desired amount of seal compression. The arrangement and flexibility of the sealing member allows the seal to adapt itself to the wide range of operating and upset conditions that typically exist for a furnace electrode seal. Frictional wear on the seal may be greatly reduced as the design inherently allows for a much lower amount of seal compression to be applied, furthermore, the seal is able to move axially which can significantly reduce wear caused by electrode regulation.

Abstract: A feed charging device comprises a holding vessel having an interior chamber for holding a reserve of a solid particulate feed material in a fluidized state, wherein the feed material is held in said fluidized state in a lower zone of the interior chamber. The feed material is supplied to the interior chamber through at least one outlet opening, and is discharged from the interior chamber through at least one outlet opening. The at least one outlet opening is in flow communication with the lower zone of the interior chamber. A gas supply means supplies a fluidizing gas to the lower zone of the interior chamber, and an outlet conduit in flow communication with the at least one outlet opening receives said feed material discharged from the interior chamber.

Abstract: A method is disclosed for controlling retention time in a reactor, such as an autoclave, having a plurality of compartments separated by dividers with underflow openings. A retention time of the reaction mixture is calculated and compared with an optimal retention time, and the volumes of the reaction mixture in the compartments are adjusted while maintaining the flow rate of the reaction mixture, so as to change the retention time to a value which is closer to the optimal retention time. The reactor may include a level sensor in the last compartment for generating volume data; a control valve for controlling the liquid level in the last compartment; and a controller which receives volume data from the level sensor and controls operation of the control valve.

Abstract: A method and apparatus for controlling a temperature within a reactor vessel such as an autoclave operating at elevated temperature and pressure. The apparatus includes a preheating vessel for preheating a feed material such as an aqueous slurry. The preheating vessel forms part of a preheating control system providing the primary means of temperature control within the reactor vessel. The apparatus also comprises secondary means for heating and cooling the reactor. Feed material temperature is increased or decreased by the preheating control system, based on the reactor temperature. Where the preheating control system is at or near its capacity for heating or cooling, the secondary heating or cooling means is activated to bring the reactor temperature within an optimum range.
