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.

Innovations in Copper: Mining Extraction: Producing ...

2021-8-12  Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect "traded" for iron by contacting the copper

2018-7-1  The extracted copper from SX–HG and SX–LG are mixed and sent to the electrowinning unit for copper deposition at 99.99% purity. The aim of this work was to investigate the removal of solids in suspension from the PLS by flocculation, and solvent extraction for copper recovery.

Copper Geoscience Australia

2021-9-14  This entire process is known as solvent extraction electrowinning (SX-EW). Various methods of smelting are used to convert the concentrates to copper metal. One method is to melt them with fluxes in a smelter furnace to produce copper matte, which is a mixture mainly of iron and copper sulfides usually containing 50 to 70% copper.
