extraction of metals - introduction
This is a common extraction process for the more reactive metals - for example, for aluminium and metals above it in the electrochemical series. You may also come across it in other cases such as one method of extracting copper and in the purification of copper.
Improved Copper/Iron Selectivity in Solvent Extraction
Inadvertently, this increased the iron co-extraction due to the large amount of excess reagent available. The slightly higher new generation reagent concentrations used, in the respective pilot-plant circuits, would therefore lead to higher recovery and would better illustrate the improved copper/iron selectivity.
SX Solvent Extraction of Metals: A Design Manual
Copper Recovery by Solvent Extraction. A common method of copper recovery from oxide ores is dump leaching in which the excavated ore is crushed and dumped on an impervious surface in "lifts" of anything from 10 to 100 ft deep. Sulphuric acid is sprayed onto the levelled off dump via a network of pipes designed to give even distribution.
