Patent number: 10626053Abstract: A method for recovering valuable metals and simultaneously preparing ceramsite by roasting cyanide tailing belongs to the area of comprehensive recovery and high value utilization of metallurgical waste residue. In this method, cyanide tailings, bentonite, calcium chloride, coal powder and albite are mixed by ball milling according to certain weight ratio to get a mixture. After drying and roasting twice, dust is collected from the roasted ash, the obtained polymetallic ash is collected and treated. The secondary calcined material is cooled to obtain ceramsite. The invention volatilizes and recovers the valuable metal in the roasting and sintering process of cyanide tailings and directly prepares the ceramsite through reasonable batching, which achieves the effect of recycling cyanide tailings and high-value utilization, can create good economic and environmental benefits, and has significant effect of energy saving and consumption reduction.Type: GrantFiled: May 28, 2018Date of Patent: April 21, 2020Assignee: BEIJING UNIVERSITY OF TECHNOLOGYInventors: Yufeng Wu, Dean Pan, Xudong Sun, Tieyong Zuo

Patent number: 7776449Abstract: A composite article that can be used as a substrate for coated conductors is disclosed. The composite substrate has at least three layers in which one or more inner layers of Ni—W alloys with 9 at. %-13 at. % W and two outer layers of Ni—W alloys with 3 at. %-9 at. % W. The content of W element gradually decreases from the inner layers to the outer layers. The composite substrate can be prepared using a process of designing and sintering composite ingot, rolling composite ingot and then annealing composite substrate. The composite substrate have a dominant cube texture on the outer layer of the whole substrate which have a weaker magnetism and higher strength than that of a single Ni-5 at. % W alloy substrate.Type: GrantFiled: June 5, 2009Date of Patent: August 17, 2010Assignee: Beijing University of TechnologyInventors: Hongli Suo, Min Liu, Yue Zhao, Meiling Zhou, Lin Ma, Tieyong Zuo
