Leaching of copper oxide ore by

Conventionally, copper oxide ores have been leached in a heap using sulphuric acid solution and leachate being further sent through downstream processes for getting pure metallic copper [BioMineWiki; G.A. Kordosky, (2002)]. The Figure 1, as follows, shows the whole process for extracting copper from oxide ore.
