One example of the way in which an ore can be purified is the froth flotation method used with ores of copper, zinc, and some other metals. In this method, impure ore taken from the ground is first ground into a powder and then mixed with water and a frothing agent such as pine oil. Then a stream of air is blown through the mixture, causing it to bubble and froth. In the frothing …
