What is an SX/EW plant? Florence Copper

2016-3-24  SX/EW technology was initially developed in Miami, Arizona, approximately 45 miles northeast of Florence, and several SX/EW facilities are scattered throughout Arizona today. Once copper laden solution, also known as pregnant leach solution (PLS) is recovered from wells on the Florence Copper property, it goes for processing at the SX/EW plant.
