Extraction of Metals from Ores – Different Processes Involved
The ferromagnetic ore particles will then get attracted and separated from the impurities easily. Froth Floatation: This is one of the methods of extraction of metals from ores by using two mediums together. Both oil and water are used to separate impurities. It can only be done when the ore forms froth when compressed air is passed in this medium.
