Patent number: 11773467Abstract: Provided are a method and a system for processing a rare earth concentrate ore. The method comprises (1) mixing the rare earth concentrate ore and concentrated sulfuric acid, thereby obtaining a mixed slurry and a first fluorine-containing gas; (2) mixing the mixed slurry and an initiator liquid for acidolysis, thereby obtaining a clinker and a second fluorine-containing gas; (3) subjecting the clinker to leaching with water, thereby obtaining a leached slurry; (4) subjecting the leached slurry to a solid-liquid separation, thereby obtaining a filtrate and a leached slag, and recycling the leached slag to step (2) for acidolysis again.Type: GrantFiled: October 25, 2019Date of Patent: October 3, 2023Assignee: CHINA ENFI ENGINEERING CORPORATIONInventors: Jianwen Tang, Guoshan Du, Pengfei Xian, Shuang Qiu, Wenlong Zhou, Bo Qin

Publication number: 20120263647Abstract: The invention provides isolated anti-ovarian, pancreatic, lung or breast cancer antigen (Pro104) antibodies that bind to Pro104 on a mammalian cell in vivo. The invention also encompasses compositions comprising an anti-Pro104 antibody and a carrier. These compositions can be provided in an article of manufacture or a kit. Another aspect of the invention is an isolated nucleic acid encoding an anti-Pro104 antibody, as well as an expression vector comprising the isolated nucleic acid. Also provided are cells that produce the anti-Pro104 antibodies. The invention encompasses a method of producing the anti-Pro104 antibodies. Other aspects of the invention are a method of killing a Pro104-expressing cancer cell, comprising contacting the cancer cell with an anti-Pro104 antibody and a method of alleviating or treating a Pro104-expressing cancer in a mammal, comprising administering a therapeutically effective amount of the anti-Pro104 antibody to the mammal.Type: ApplicationFiled: December 16, 2011Publication date: October 18, 2012Applicant: diaDexus, Inc.Inventors: Jackie Papkoff, Glenn Pilkington, Gilbert-Andre Keller, Wenlu Li, Laura Corral, Iris Simon, Muriel Kmet, Jianwen Tang
