Extraction of Metals Extraction of Titanium The extraction of titanium uses the Kroll process Titanium ore is called rutile Rutile contains titanium dioxide - TiO 2 Titanium dioxide is converted into titanium chloride - TiCl 4 Titanium is more reactive than carbon but it is not extracted by electrolysis because titanium chloride is covalent and therefore does not conduct electricity

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 extract from its compound Electrolysis Electrolysis is the most powerful extraction method But it takes a lot of electricity and that makes it expensive
First the lead ore is ground into small particles that are less than 01mm, giving the ore a texture similar to table salt Next the lead powder is put through a flotation process, that involves mixing the lead ore with water, the addition of pine oil and the introduction of air bubbles and agitation which forms an oil froth, containing the lead ore, on the surface
