  • Publication number: 20210130926
    Abstract: The present invention relates to a method for recovering nickel and cobalt from a nickel, iron, and cobalt-containing raw material. According to the present invention, high concentrations of valuable metals, such as nickel and cobalt, can be recovered from a raw material containing nickel, iron, and cobalt, and especially, the concentrations of nickel and cobalt are low and the concentration of iron is high, and thus when nickel is leached, and relatively large amount of iron is leached, whereas a small amount of nickel is leached. Therefore, the present invention can be more suitably applied in the smelting of nickel ore in which the separation of iron and nickel is difficult.

  • Publication number: 20210044691
    Abstract: This disclosure generally relates to various directional input units of a mobile communication terminal, where such directional input units receive a single user input or multiple concurrent user inputs and then acquires at least one selecting (user) sub-input therefrom while a terminal is in its powered-off state or its off-state. After acquiring the selecting user sub-input, a terminal runs at least one pre-selected operation which is selected from a set of multiple pre-selected operations and which matches the selecting user sub-input when a terminal powers on from its powered-off state or wakes up from its off-state. A directional input unit may acquire the selecting user sub-input from a movement of at least a portion thereof, a contact between at least a portion thereof and a user body part, or the like. As a result, a terminal can provide a user with more seamless operations.
