  • Publication number: 20230250508
    Abstract: Provided is a method that allows for efficient removal of an impurity metal, and further, the recovery of a valuable metal with high efficiency. The method for recovering a valuable metal (Cu, Ni, and Co) includes the steps of: preparing a charge comprising at least a valuable metal as a raw material; heating and melting the raw material to form an alloy and a slag; and separating the slag to recover the alloy containing the valuable metal, wherein the heating and melting of the raw material comprises charging the raw material into a furnace of an electric furnace equipped with an electrode therein, and further melting the raw material by means of Joule heat generated by applying an electric current to the electrode, or heat generation of an arc itself, and thereby separating the raw material into a molten alloy and a molten slag present over the alloy.

  • Publication number: 20230054799
    Abstract: A charging device basically includes a first power source, first and second device-side connection terminals, a first resistance, a detection unit and a device-side controller. The first resistance is connected between the first power source and the first device-side connection terminal. The detection unit detects an inter-terminal voltage between the first device-side connection terminal and the second device-side connection terminal. A vehicle-side controller is connected between a first vehicle-side connection terminal connected to the first device-side connection terminal and a second vehicle-side connection terminal connected to the second device-side connection terminal. The device-side controller determines that the charging-device-side charging connector and the vehicle-side charging connector are turned into a non-connected state from a connected state by a fact that the inter-terminal voltage detected by the detection unit becomes greater than a predetermined voltage.
