Professional Experience

Freeport-McMoRan Copper & Gold, Inc., Morenci Hydrometallurgical Operations, Morenci, AZ Jun 2009 – May 2011

Metallurgist I, Supervisor: Rosa Schnebly

• Supervised solvent extraction (SX) and electrowinning (EW) plant operations.

• Rectified SX plant design issue that was causing increased organic entrainment. Initiated a design change that resulted in a 60% decrease in organic entrainment.

o Results were published in Solvent Extraction and Ion Exchange.

• Designed new chevron to improve flow distribution in the SX settlers. Design adopted by company for all SX operations.

• Evaluated a BioTector TOC analyzer to perform in-line organic entrainment measurements.

o Identified flaw in design that the supplier is working to correct.

Freeport-McMoRan Copper & Gold, Inc., Technology Center, Safford, AZ Jun 2009 – May 2011

Research Engineer I, Supervisor: Jason Morgan

• Participated in the Graduate Development Program through the SX/EW Test Facility.

• Tested a new SX extractant in order to compare performance to extractants currently in use.

• Studied the effects of air sparging on EW cathode to determine if air sparging could improve cathode quality.
