| Abstract: | This article compiles the results of a review of world copper solvent extraction (SX) plant practices and examines changes in operating practices in the last seven years as compared to previous world copper SX surveys in 1996 and 1999. Trends covered are fiber-reinforced plastic construction mixer box and settler designs, reverse flow settlers, and advanced mixer design. These changes have resulted in improved capital and operating costs. For more information, contact Tim Robinson, Phelps Dodge Mining Co., Process Technology Center, 9780 E.
