Publication number: 20060144717Abstract: The present invention relates generally to a process for recovering copper and/or other metal values from a metal-bearing ore, concentrate, or other metal-bearing material using pressure leaching and direct electrowinning. More particularly, the present invention relates to a substantially acid-autogenous process for recovering copper from chalcopyrite-containing ore using pressure leaching and direct electrowinning in combination with a leaching, solvent/solution extraction and electrowinning operation.Type: ApplicationFiled: October 28, 2005Publication date: July 6, 2006Applicant: PHELPS DODGE CORPORATIONInventors: John Marsden, Robert Brewer, Joanna Robertson, David Baughman, Philip Thompson, Wayne Hazen, Christel Bemelmans, Susan Brewer

Patent number: 7062310Abstract: An electrode assembly for a sensor catheter tip includes a first electrode and a second electrode each having a central axis. The two electrodes are axially aligned and spaced apart along the axis. Each of the first and second electrodes comprises a contact aperture spaced from the center axis, and a contact element positioned within each of the contact apertures. The center axis of each of the first and second electrodes is substantially aligned, and the contact elements corresponding to each of the first and second electrodes are offset, thereby providing staggered contact points for each respective electrode.Type: GrantFiled: October 6, 2003Date of Patent: June 13, 2006Assignee: Tyco Electronics CorporationInventors: William Henry Bernhart, John Philip Thompson, John Raymond Penica, Paul Steven Sremcich, John E. Hampton, Brent David Yohn, Keith Miller

Patent number: 7041152Abstract: The present invention relates generally to a process for the production of sulfuric acid and liberation of precious metal values from materials containing sulfur through pressure leaching operations. In accordance with various aspects of the present invention, the sulfur-bearing materials may comprise residues from pressure leaching operations, such as those carried out at medium temperatures. The process of the present invention can be advantageously used to convert such sulfur-bearing materials to sulfuric acid by means of pressure leaching. The sulfuric acid so produced can be used beneficially in other mineral processing operations, for example those at the site where it is produced. Metals, such as precious metals, that are contained within the sulfur-bearing materials advantageously may be recovered from processing products by established precious metals recovery technology.Type: GrantFiled: March 29, 2005Date of Patent: May 9, 2006Assignee: Phelps Dodge CorporationInventors: John O. Marsden, Robert E. Brewer, Joanna M. Robertson, Wayne W. Hazen, Philip Thompson, David R. Baughman

Patent number: 6972107Abstract: A system and process for recovering copper from a copper-containing ore, concentrate, or other copper-bearing material to produce high quality cathode copper from a leach solution without the use of copper solvent extraction techniques or apparatus. A process for recovering copper from a copper-containing ore generally includes the steps of providing a feed stream containing comminuted copper-containing ore, concentrate, or other copper-bearing material, leaching the feed stream to yield a copper-containing solution, conditioning the copper-containing solution through one or more physical or chemical conditioning steps, and electrowinning copper directly from the copper-containing solution, without subjecting the copper-containing solution to solvent extraction.Type: GrantFiled: December 15, 2003Date of Patent: December 6, 2005Assignee: Phelps Dodge CorporationInventors: John O. Marsden, Robert E. Brewer, Joanna M. Robertson, David R. Baughman, Philip Thompson, Wayne W. Hazen, Christel M. A. Bemelmans

Publication number: 20050155458Abstract: The present invention is directed to a system for recovering metal values from metal-bearing materials. During a reactive process, a seeding agent is introduced to provide a nucleation site for the crystallization and/or growth of solid species which otherwise tend to passivate the reactive process or otherwise encapsulate the metal value, thereby reducing the amount of desired metal values partially or completely encapsulated by such material. The seeding agent may be generated in a number of ways, including the recycling of residue or the introduction of foreign substances. Systems embodying aspects of the present invention may be beneficial for recovering a variety of metals such as copper, gold, silver, nickel, cobalt, molybdenum, zinc, rhenium, uranium, rare earth metals, and platinum group metals from any metal-bearing material, such as ores and concentrates.Type: ApplicationFiled: March 29, 2005Publication date: July 21, 2005Applicant: PHELPS DODGE CORPORATIONInventors: John MARSDEN, Robert BREWER, Joanna ROBERTSON, David BAUGHMAN, Philip THOMPSON, Wayne HAZEN, Roland Schmidt

Publication number: 20050124301Abstract: An exemplary antenna switching circuit comprises first, second, third and fourth switches. The first switch is activated by a first control signal for establishing a connection between a first transmit port and an antenna; the second switch is activated by a second control signal for establishing a connection between a second transmit port and the antenna; the third switch is activated by a third control signal for establishing a connection between a first receive port and the antenna; and the fourth switch is activated by the third control signal for establishing a connection between a second receive port and the antenna. With this arrangement, the first receive port and the second receive port are simultaneously connected to the antenna when the third switch and the fourth switch are activated by the third control signal.Type: ApplicationFiled: December 4, 2003Publication date: June 9, 2005Inventors: Norbert Schmitz, Mark Ayvazian, Philip Thompson, Edward Lawrence, Darryl Evans, David Johnson
