The ore or the mineral usually contain different metals. But the point is that the metals don’t exist in a free state. Usually they exist as an oxides, for example : Bauxite ‒Al2O3 Haematite ‒Fe2O3 Rutile ‒ TiO2 So the simplest thing you can do before extracting the metal is to reduce it or in other words to  remove  oxygen.  For  example : titanium  is  producedby  turning  titanium  dioxide  intotitanium(IV)  chlorideand  reducing  itusing  a  more  reactive  metal  such  as  sodium  or magnesium. Magnaliumis  analuminiumalloy  with  5%magnesiumand  95%aluminum.This  alloy  is  used in metallurgyas  a reduction  agent that  removes  oxygen  and sulfurfrom  the  ores,  giving insoluble in water oxides and sulphides, because both metals in the composition are active. Another reason of usage is that both metals and their compounds have low density.
