  • Patent number: 9063110
    Abstract: A method, implemented by a software-controlled computer device and/or by dedicated hardware, for probing an electrically conductive target material, e.g. molten metal or semiconductor material, in a metallurgical vessel. In the method, a measurement signal is acquired from a sensor, which is inserted into the target material, during a relative displacement between the electrically conductive target material and the sensor, the measurement signal being indicative of electrical conductivity in the vicinity of the sensor. The measurement signal is generated to represent momentary changes in an electromagnetic field around the sensor, which is created by operating at least one coil in the sensor. Based on the measurement signal, a signal profile is generated to be indicative of the electrical conductivity as a function of the relative movement. The method enables a probing of the internal distribution of the target material in the vessel at any level of detail.

    Abstract: A system and method are provided for the extraction of gold and other precious metals and elements from ore, as well as purification of water. Heavy elements are separated from lighter elements during the rotation of any conductive liquid in a chamber. To provide proper conductivity seawater can be used as the main conductive liquid. An electric field and hence a current is generated in a radial direction in a magnetic field generated in an axial direction, perpendicular to the radial direction, with respect to a chamber. The conductive liquid is provided to the chamber and is subjected to the current, and the conductive liquid is caused to rotate in the chamber by the current interacting with the magnetic field. Due to the Lorentz force, proper rotation is achieved without any mechanical motion. Rotation of the liquid in the chamber causes separation of heavy elements from light element caused by centrifugal forces.

  • Publication number: 20130032006
    Abstract: The invention is directed to a method for inducing a surface stress-induced volumetric change in a nanoporous material and to a device for carrying out the method. The method of the invention comprises—accumulating polar molecules onto the surface of the nanoporous material by physical adsorption of the polar molecules from the vapour phase thereby inducing surface stress to said surface; or—dissipating accumulated polar molecules from the surface of the nanoporous material by physical desorption of the polar molecules into the vapour phase thereby inducing surface stress to said surface, wherein the nanoporous material comprises a nanoporous metal or alloy. The device comprises a) a nanoporous metal material which, upon physical adsorption from the vapour phase or physical desorption into the vapour phase of polar molecules onto or from the surface of the nanoporous metal material, exhibits a volumetric change; and b) a mechanism for detecting and/or transferring the volumetric change.

  • Patent number: 8287802
    Abstract: There is provided a method and an apparatus for treating return ores using plasma, capable of treating sintered return ores generated in a sintering process in a steel maker or return ores (iron ores) employed in other ironmaking process such as FINEX. The method of treating return ores using plasma includes: providing return ores sorted out by a sorting process; and bonding the return ores by fusing and agglomerating the return ores using plasma. Also, an apparatus for treating return ores using plasma includes a plasma heating device used to fuse and agglomerate sorted return ores. The return ores of a predetermined grain size are fusion-bonded and agglomerated using a flame of a plasma heating device. Particularly, the return ores can be treated in a massive amount to enhance productivity of a fusion-bonding process of the return ores. Furthermore, a great amount of sintered return ores generated in the sintering process can be subjected to a fewer number of re-treatment processes.
