The difference between regular shungite and elite or noble shungite is in the proportion of organic carbon in it. Regular shungite contains from 35 to 60 per cent of organic carbon while the percentage of carbon in elite shungite is much higher and totals from 92 to 98 per cent.
Strunzite is a phosphate mineral of iron and manganese. Graftonite is a phosphate mineral of iron, manganese and calcium. Iron appears with magnesium and aluminum in the phosphate lazulite. Iron, magnesium and manganese form the phosphate mineral ludlamite.Phosphates of aluminum and iron are vauxite and paravauxite. A phosphate of iron and lithium is triphylite. Nickel is often found in association with iron and sometimes forms the compound Ni 3 Fe, called awaruite in its mineral form.Nickel-iron meteorites are fairly common. Common useful forms of iron alloys are cast iron, wrought iron, and steel.Wrought iron is made from cast iron by melting it on a bed of iron oxide. The final result is a material which is nearly pure iron, with only 0.1-0.2% of carbon and less than 0.5% of all impurities.trunzite is a phosphate mineral of iron and manganese. Graftonite is a phosphate mineral of iron, manganese and calcium. Iron appears with magnesium and aluminum in the phosphate lazulite.
