US Patent:

20120085706, Apr 12, 2012
Filed:

Oct 7, 2010
Appl. No.:

12/899935
Inventors:

Charles L. Bryce - Pima AZ, US
Jason M. Morgan - Morenci AZ, US
William R. Sircy - Thatcher AZ, US
Rosemary D. Blosser - Thatcher AZ, US
Assignee:

FREEPORT-MCMORAN CORPORATION - Phoenix AZ
International Classification:

B01D 11/00
US Classification:

210643, 210 962
Abstract:

The present invention relates to a method and article for manipulating an amount of organic material entrained in an aqueous phase of a solvent extraction process. The method includes estimating an interfacial shear stress between an aqueous phase and an organic phase of a solvent extraction apparatus, estimating an amount of organic material entrained in the aqueous phase based on the estimated interfacial shear stress, and manipulating one or more solvent extraction process parameters to manipulate the amount of organic material entrained in the aqueous phase. The method and apparatus can be used to improve performance of and reduce operating costs associated with the solvent extraction apparatus.

US Patent:

20130153435, Jun 20, 2013
Filed:

Dec 20, 2011
Appl. No.:

13/331661
Inventors:

Scot P. Sandoval - Morenci AZ, US
Casey J. Clayton - Morenci AZ, US
Jason M. Morgan - Morenci AZ, US
Charles L. Bryce - Pima AZ, US
Brett Waterman - Tucson AZ, US
Assignee:

FREEPORT-MCMORAN CORPORATION - Phoenix AZ
International Classification:

C25B 11/00
C25C 1/00
C25B 9/00
US Classification:

205560, 2042861, 204242
Abstract:

A cathode assembly, a system including the cathode assembly, and method of using the assembly and system are disclosed. The cathode assembly includes high surface area material to allow efficient recovery of metal at reduced current densities at the cathode, which allows increased rates of metal recovery to be obtained, while maintaining desired properties of the electrowon metal.
