Types of Extraction | Scool, the revision website

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to ...

· On the contrary, as for the FeMn ores with high iron content, the iron ions concentration of the solution is high even if the iron leaching efficiency is only 20–30%. The leaching of FeMn ores in the presence of oxalic acid and methanol presents better selective leaching effect of manganese and iron, but it's uneconomic owing to the high price of the organic reductants. In addition, the ...
