Details for the extraction of aluminum, copper, iron and titanium are given in separate pages in this section. What are "ores"? An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminum, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals.

Moreover, the membranes proved to be more effective in the removal of copper ions than iron ones and phenol. The membranes were found to show higher effectiveness in copper removal from a solution of the initial concentration of 800 mg/L. The most efficient in copper ions removal was the membrane containing urea-enriched …

The extraction of copper and iron increases linearly as the leaching temperature increases from 20 to 60 °C. Copper extraction was 80% after 2 h at 60 °C with the addition of the oxidant ferric sulfate at a concentration of 5 g/L Fe 3+ ions. The highest degree of copper leaching was observed at a stock consistency of 33%.

Copper and cobalt can be found on nickel laterite ores, and cobalt can be found also on copper ores, and many contaminants such as iron, aluminum, and magnesium are associated with these ores. In hydrometallurgical process, a purification step is necessary after leaching due to the presence of these impurities. Chelating …
