Patent number: 8979974Abstract: The present invention provides a composition for collecting a metal component from a metal component-containing material, the composition containing a compound containing at least one element selected from the group consisting of lanthanoid elements and elements in group 2 of the periodic table, and a compound containing at least one element selected from the group consisting of elements in groups 3, 4, 12, and 13 of the periodic table and transition metal elements in the 4th period of the periodic table. The present invention further provides a method for collecting a metal component using this composition. With the use of the composition of the present invention, a metal component can be easily and efficiently collected from a material containing a highly useful metal component such as noble or rare metal.Type: GrantFiled: June 21, 2013Date of Patent: March 17, 2015Assignee: National Institute of Advanced Industrial Science and TechnologyInventors: Katsuhiro Nomura, Hiroyuki Kageyama, Masakazu Date, Tadahiro Fujitani

Patent number: 8623113Abstract: The present invention provides a metal component collection agent for collecting one or more metal components from a metal component-containing material; the agent containing, as an active ingredient, a compound containing one or more group 2 elements of the periodic table, or a compound containing one or more lanthanoid elements. The present invention further provides a method for collecting one or more metal components from a metal component-containing material; the method comprising heating the metal component-containing material and the metal component collection agent in such a manner that a metal vapor or metal oxide vapor produced by heating the metal component-containing material is brought into contact with the metal component collection agent. According to the present invention, metal components can be easily and efficiently collected from materials containing highly useful metal components such as noble or rare metal.Type: GrantFiled: March 29, 2011Date of Patent: January 7, 2014Assignee: National Institute of Advanced Industrial Science and TechnologyInventors: Katsuhiro Nomura, Hiroyuki Kageyama
