hydrometallurgical processingof a variety of precious and base metals. La rge-scalecopperplants treating over 550 ,000 m 3 of solution per day are found in Arizona a nd

Cathodes are re-melted under controlled conditions and cast into forms suitable for furtherprocessing.Modern methodsof extraction allow economic leaching and electro-winning ofcopperfrom low-grade ores and extraction techniques are continuously being refined and developed to achieve the most efficient removal ofcopperfrom a wide variety ...

The invention relates to amethodfor producingcopperin ahydrometallurgical processfromcopper-bearing raw materials, such as sulfidic concentrates. The concentrate is leached in a leaching stage of several steps into a chloride-based solution. Thecopper-bearing solution obtained from this leaching is subjected to reduction and solution purification, whereafter thecoppercontained in the ...

The early development ofcopperprobably was most advanced in Egypt.As early as 5000 bce,copperweapons and implements were left in graves for the use of the dead.Definite records have been found of the working ofcoppermines on the Sinai Peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art of extracting the metal included some refining.

Hydrometallurgical Modern Copper Processing Methods.Hydrometallurgical methodsalone or in combination with flotation have mainly been applied to large tonnage operations to recovercopperfrom low grade nativecopperoxidized or mixed oxide and sulfide ores that are not readily concentrated by flotation alone.

Copper processingis a complicatedprocessthat begins with mining of the ore (less than 1%copper) and ends with sheets of 99.99% purecoppercalled cathodes, which will ultimately be made into products for everyday use.The most common types of ore,copperoxide andcoppersulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Tungsten is one of the most important refractory metals. It is used in the production of numerous end-use items such as incandescent lamps and hard materials. From its ore concentrates and oxidized scrap, tungsten is processed via ahydrometallurgicalroute. In the last 100 years there has been a significant change in itsprocessing. This paper reviews themethodsemployed in the ...

Pyrometallurgical processesresulted in the formation of approximately 3.4 t of SO 2 for every 1 t ofcopper. Thehydrometallurgical processincluded pressure leaching under slightly oxidising conditions in diluted sulphuric acid (at 80–105 °C and 140-350 kPa oxygen pressure). This enabled selective extraction of up to 97% ofcopper, with less than 10% of pyrite taking part in the reaction.
