How hydrometallurgy and the sx/ew process made copper the introductionconventional copper extractionthe sx/ew processbacterial leachingconclusioncontacts and referencesalso in this issue copper is traditionally known as the red metal after its natural color. however, it is also known as a green metal for the green patina that it acquires due to.
Hydrometallurgical (leaching) process leaching, solvent extraction (sx) and electro-winning (ew) have been used for producing copper from oxide ores since the 1960s and since the 1980s some secondary sulfide ores, such as chalcocite, can also be treated in this manner. figure 1 shows one possible flowsheet for the leaching.
In this paper the current status of the modeling, simulation and control of the copper-leaching, solvent-extraction and electrowinning process (lx/sx/ew) is.

Oxide ore is treated via crushing, milling, flotation, leaching and sx–ew to produce sulphidic and gold-bearing flotation concentrates, as well as electrowon cathode copper (fqm, 2015). the hydrometallurgical circuit employs both pressure and atmospheric leaching steps, and has five sx circuits and three.
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-bearing solution with scrap.
The pregnant leach pond contains copper ions that give it the blue colour of copper sulfate. the liquid is continually pumped to the sx-ew plant. 3. copper sulfate solution is collected in the pregnant leach pond then pumped to the solvent extraction plant. the solvent extraction phase of.
The run-of-the-mine (rom) ore from the primary crusher at the santa rita open-pit undergoes secondary crushing and grinding followed by conventional froth-flotation at the ivanhoe concentrator for the production of copper and molybdenum concentrates. the sx/ew produces copper cathode by processing the solution generated by rom.
