Patent number: 8900535Abstract: In an embodiment, the present invention relates to an apparatus and a process for producing a concentrated form of basic zinc sulphate from a, typically dilute, acidic zinc sulphate-bearing solution. The process embodiment comprises the steps of precipitating the zinc, preferably primarily as basic zinc sulphate, from the acidic zinc sulphate solution, preferably using calcium oxide, in such a way as to promote the formation of separate gypsum crystals and basic zinc sulphate particles, and upgrading the zinc content in the precipitates by separating the basic zinc sulphate from the gypsum using size separation techniques.Type: GrantFiled: January 7, 2011Date of Patent: December 2, 2014Assignee: Barrick Gold CorporationInventor: Yeonuk Choi

Patent number: 8546292Abstract: A zinc-carbon compound that is a reaction product of zinc and carbon, wherein the zinc and the carbon form a single phase material that is meltable. The compound is one in which the carbon does not phase separate from the zinc when the single phase material is heated to a melting temperature.Type: GrantFiled: November 15, 2012Date of Patent: October 1, 2013Assignee: Third Millennium Metals, LLCInventors: Jason V. Shugart, Roger C. Scherer

Patent number: 7175691Abstract: A method of producing stainless steel includes the steps of melting a raw material in an electric furnace to form molten steel, and then refining the molten steel by a refining furnace to produce stainless steel in a stainless steel producing process. In the method, a carbonaceous reducing agent is added to a zinc-containing waste material produced in the stainless steel producing process, the resultant mixture is agglomerated by a briquette press to form agglomerates incorporated with a carbonaceous material, the agglomerates incorporated with the carbonaceous material are heated in a rotary hearth furnace to reduce and evaporate zinc to form dezincified agglomerates, and then the dezincified agglomerates are charged as a coolant in an oxidation period of the refining furnace.Type: GrantFiled: May 15, 2003Date of Patent: February 13, 2007Assignee: Kobe Steel, Ltd.Inventors: Hiroshi Sugitatsu, Itsuo Miyahara

Patent number: 5871561Abstract: Dusts containing zinc and/or lead in the form of oxides and one or more reducing agents are mixed with each other before or after being introduced into a heat treatment furnace. The mixture is heated to a given temperature range under a substantial vacuum so that the zinc and/or lead in the form of oxides are reduced to zinc and/or lead in the state of pure metals and evaporated in the furnace. The evaporated zinc and/or lead are introduced into a retrieving container also under a substantial vacuum and at a given temperature where the evaporated zinc and/or lead pure metals are condensed and retrieved.Type: GrantFiled: May 30, 1996Date of Patent: February 16, 1999Assignees: Toyota Jidosha Kabushiki Kaisha, Aichi Steel Works, Ltd., Toyokin Kabushiki KaishaInventors: Yuji Okada, Hirokazu Shirakawa, Masamichi Okada, Toshikatsu Hara, Hirohiko Sasamoto, Kazuhiro Suzuki

Patent number: 4961777Abstract: An agglomerative heap leaching method for recovering gold, silver or other metals from low grade refractory ores. Hypochlorite compounds are incorporated directly into the ore agglomerates as they are formed. This provides ample time and opportunity for the hypochlorite to destroy, modify or passivate refractory components of the ore thereby improving metal recovery in the subsequent cyanide leaching step.Type: GrantFiled: August 3, 1988Date of Patent: October 9, 1990Assignee: Freeport-McMoRan, Inc.Inventors: Jesus W.
