The presence of pyrite and pyrrhotite in sulphide ores is undesirable and usually methods have to be found to remove them [2]. Ilmenite is a source of titanium as well as iron. Although titanium minerals are used for producing titanium metal, yet 99%
PentlanditeThe fraction of nickel in pentlandite (nickel ore) is only × 10 −3 g Ni/g ore. To supply 1 g of pure nickel to an industrial process requires that at least 181 g of pentlandite be dug. If the nickel mine is underground, the upper layers of topsoil and clay are also excavated, perhaps a forest is also cut and biotic material degraded.
