Publication number: 20110293506Abstract: An object (first object) of the invention is to provide a waste water treatment technology (pretreatment technology in particular) which makes it possible to recover fluorine at a high recovery rate as highly pure calcium fluoride, without diluting waste water containing fluorine and silicon, i.e. to recover fluorine from high-concentration waste water containing fluorine and silicon. Waste water containing fluorine and silicon is supplied to a pH controlling tank 1 and sodium hydroxide (NaOH) is added thereto, with the result that sodium silicate is precipitated. Thereafter, the waste water is supplied to a solid-liquid separator 2 so that solid-liquid separation of sodium silicate is conducted.Type: ApplicationFiled: February 9, 2010Publication date: December 1, 2011Applicant: Kobelco Eco-Solutions Co., Ltd.Inventors: Katsuyoshi Tanida, Tsutomu Kinoshita, Hiroyuki Chifuku, Sousuke Onoda

Publication number: 20110132146Abstract: An object is to provide a method and an apparatus for recovering indium, the method and apparatus ensuring that it is unnecessary to recover indium in the form of indium hydroxide, indium can be recovered at a high concentration, indium can be recovered easily by a filter or the like without handling inferiors and also, the recovery rate of indium is greatly improved. The method includes adding a precipitation-inducing metal including a metal having higher ionization tendency than indium to an etching waste solution containing at least indium and ferric chloride, in which the concentration of ferric chloride is adjusted to 20% by weight or less to thereby precipitate indium contained in the etching waste solution on the surface of the precipitation-inducing metal, then, detaching the indium precipitated on the precipitation-inducing metal from the precipitation-inducing metal by a detaching means and separating the detached solid indium or indium alloy from the solution to recover the indium.Type: ApplicationFiled: November 19, 2007Publication date: June 9, 2011Applicants: SHARP KABUSHIKI KAISHA, KOBELCO ECO-SOLUTIONS CO., LTD.,Inventors: Takeo Miki, Tamotsu Sugimoto, Eiichi Sahashi, Takamichi Honma, Tomoharu Maeseto
