摘要： A flux used for an electroslag remelting method is in granular form at 25°C, in which, when passed through a sieve having a nominal opening of 500 um defined in accordance with JIS Z 8801-1:2019, the flux has a passing rate of 18% or less, the passing rate being a ratio of a mass of the flux that fell under the sieve to a mass of the flux before sieving.

摘要： Provided is a method for safely and efficiently recovering a valuable metal from a material including waste lithium ion batteries or the like. The present invention is for producing a valuable metal from a material including the valuable metal, the method comprising: a preparation step for preparing a material including at least Li, Al, and a valuable metal; a reduction and melting step for carrying out a reduction and melting process on the material to obtain a reduced product including a slag and an alloy containing a valuable metal; and a slag separation step for separating the slag from the reduced product to recover the alloy. In the preparation step and/or the reduction and melting step, a flux containing Ca is added to the material. In the reduction and melting step, the reduction and melting process is carried out such that the mass ratio of aluminum oxide / (aluminum oxide + calcium oxide + lithium oxide), in the generated slag, is set to 0.5-0.65, and the slag heating temperature is set to 1400-1600°C.

摘要： A process for producing technetium-99m from a molybendum-100 metal powder, comprising the steps of: (i) irradiating in a substantially oxygen-free environment, a hardened sintered target plate coating with a Mo-100 metal, with protons produced by a cyclotron; (ii) dissolving molybdenum ions and technetium ions from the irradiated target plate with an H 2 O 2 solution to form an oxide solution; (iv) raising the pH of the oxide solution to about 14; (v) flowing the pH-adjusted oxide solution through a resin column to immobilize K[TcO 4 ] ions therefrom; (vi) eluting the bound K[TcO 4 ] ions from the resin column; (vii) flowing the eluted K[TcO 4 ] ions through an alumina column to immobilize K[TcO 4 ] ions thereon; (viii) washing the immobilized K[TcO 4 ] ions with water; (ix) eluting the immobilized K[TcO 4 ] ions with a saline solution; and (x) recovering the eluted Na[TcO 4 ] ions.
