Copper under the stars: The history of discovery and

2020-7-8  The Girilambone mine with its low-grade oxide-carbonate resource languished until 1990, when it was realised that a new two-stage, hydrometallurgical process of bulk heap leaching followed by solvent extraction and electrowinning could efficiently and profitably extract large amounts of high quality copper from the near surface parts

Experience in operating the girilambone copper SX-EW

1997-5-1  The process plant at GCC, uses heap leaching (HL) followed by solvent extraction (SX) and electrowinning (EW) to recover copper as LME grade `A' metal (Figure 1). Leaching is accomplished with dilute sulphuric acid solutions, which dissolve the copper and other chemically amenable ore constituents.
