Growing role of solvent extraction in copper ores processing
Heap leaching of oxide copper ores and cathode copper recovery by solvent extraction (SX) and elec- trowinning (EW) has been well established as a primary low-cost hydrometallurgical copper recovery method. Subsequently, hydrometallurgy was also gradually developed and applied for sulphidic ores and concentrates.

Copper-Nickel Ore Processing
Copper Solvent Extraction. The separation of copper from nickel is based on the fact that there is an appreciable difference in the pH at which the two metals are extracted. Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper raffinate at pH 8.0 to 8.2.
