Abstract: Pyro-hydrometallurgical methods are described to economically and environmentally recover a target metal from iron slag or steel slag. For instance, the method can enable subjecting an iron or steel slag feed to acid-baking with an acid to produce a dried mixture comprising at least one soluble metal salts, then subjecting the dried mixture to water leaching to an aqueous solution comprising an aqueous leachate rich in said target metal and solid residues and subsequently separating the aqueous leachate rich in said target metal from the solid residues. This acid-baking water-leaching method facilitates efficient recovery of target metal compared to conventional methods.

Abstract: An off-gas analyzer for analyzing H2O vapor, CO, O2, CO2 and/or H2 in a furnace gas stream is fluidically coupled to a gas extraction probe. The analyzer includes an optical measurement cell having multiple sampling chambers, optically coupled to a laser. The analyzer measuring cell is housed within a heated cabinet having a heater operable to heat the interior thereof so as to maintain the extracted gas sample therein at a temperature about the condensation point of water. The analyzer allows for the analysis of the gas water vapour of wet off-gas samples.

Abstract: A system used in monitoring one or more operating parameters of a coolant-fluid cooled industrial installation includes one or more an acoustic sensors positioned to receive and sense one or more acoustic signals in an installation coolant-fluid flow. The acoustic sensor assembly operates to emit and sense acoustic signals at frequency ranges above and/or below the background noise frequency ranges which are associated with the normal industrial installation operation. Output data signals representative of sensed acoustic signals are compared to target frequency profiles predetermined as representing an acoustic frequency associated with a predetermined installation operating parameter or event.

Abstract: An optically based combustion off-gas stream velocity sensor assembly is provided for detecting in real-time off-gas flow velocity and/or volume as it moves through a flue duct. The sensor assembly includes two paired coherent light emitters and optic sensors, positioned in a spaced orientation in the flow path direction. The light emitter/optic sensor pairs operate to emit and detect across the off-gas stream coherent light beam energy having a wavelength component corresponding to an absorption profile of an off-gas species component. The detection of non-absorbed portions of the emitted beam is used to identify and detect the movement of a flow species signature at different locations along the flue duct.

Abstract: Electrorefining cells and methods for electrorefining ferrous molten metal (e.g. steels), that includes impurities (e.g., carbon), are described. Liquid metal is provided in ladle with a molten electrolyte on top of it to form a metal-electrolyte interface. An electrode connection is put into contact with the metal for electronic conduction therewith, while a counter electrode is put into contact with the electrolyte for forming an electrolyte-counter electrode interface. Both the electrode connection and the counter electrode remain in the solid form in, and inert to, the metal and the electrolyte, respectively. The electrode connection and the counter electrode are made of an electronically conductive material. Therefore, during electrorefining operations, an electromotive force can be supplied between the electrode connection and the counter electrode so as to induce electrochemical reactions to occur at both the metal-electrolyte interface and the electrolyte-counter electrode connection, producing a ferrous molten metal depleted of the impurities.
