Abstract: A Mg removal agent is composed of a chloride and copper oxide. The chloride contains at least Mg and one or more base metal elements selected from K, Na, and Ca. The chloride contains, for example, 0.2 to 60 mass % of MgCl2 and/or 40 to 99.8 mass % of KCl with respect to the chloride as a whole. The compounding ratio that is a mass ratio of the chloride to the copper oxide is, for example, 0.15 or more. The chloride may be a re-solidified salt or a mixed salt. At least a part of the chloride may be a mineral containing the base metal elements and Mg or a mineral-derived chloride. A preferred example of the Mg removal agent is granular flux introduced into the aluminum alloy molten metal.

Abstract: Provided is a method of recycling carbon fibers that allows obtaining continuous carbon fibers. The present embodiment is a method of recycling carbon fibers that includes preparing a carbon fiber reinforced plastic molded product including carbon fiber reinforced plastic containing carbon fibers and a resin and drawing the carbon fiber reinforced plastic while performing a heating treatment on the carbon fiber reinforced plastic molded product. A temperature of the heating treatment is equal to or above a glass-transition temperature of the resin and below a thermal decomposition start temperature, and the temperature is below a thermal degradation temperature of the carbon fibers.

Abstract: A metal purifying method having: a local heating step of heating an aluminum-based molten metal in a first region on a molten metal surface of the aluminum-based molten metal; and a local low pressure step of lowering the pressure in a second region on the molten metal surface to a pressure lower than the pressure in the first region. The second region is different from the first region. This allows a specific element to be vaporized from the second region to purify the aluminum-based molten metal. The specific element is one or more of Zn, Mg, or Pb having a saturated vapor pressure higher than that of Al. This is effective not only in a purifying method for removing a specific element from an aluminum-based molten metal but also in a method of recovering a specific element, which can be a resource, from an aluminum-based molten metal.
