    The extracted alumina and silica gel have high purity and are used as high added value products. The separation extraction rates of the alumina and the silica gel in the fly ash reach more than 90%. The residue amount obtained after extracting the alumina and the silica gel from the fly ash is less than 10% of the fly ash.

    Ilmenite by virtue of being rich in iron often has small concentrations of impurities such as Mn 3 O 4, Al 2 O 3, CaO, Cr 2 O 3, and MgO. Removal of iron and other impurities is essential for the production of pigment grade TiO 2 . An investigation of the removal of iron was undertaken by roasting the mineral ilmenite with soda ash in air above 873 K.

    The openhearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an openhearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface. Impurities, including carbon, are oxidized and float out of the iron into the slag.
