Secondary production. Over 50% of the aluminium used to make new products comes from scrap, of which two thirds is 'new scrap'. Aluminium can be easily recycled at low cost (using about 5% of the energy required for primary production) and approximately 60% of European consumption is recycled metal. It has even been estimated that two-thirds of ...
of aluminum-sodium-hydroxy fluoride, analogous to ralst-onite, were established. Finally, solubility-phase transition diagrams were com puted for equilibria involving gibbsite and cryolite. The relationships are valid for systems low in dissolved silica. The solubility of aluminum …
to the problem is to recycle the used fabricated aluminum into other useful products or into aluminum compounds. This research illustrate a chemical process in which waste aluminum is converted chemically into an aluminum compound i.e. hydrated potassium aluminum sulfate, KAl(SO 4) 2 •12H 2 O, or commonly known as Alum.
About half of total aluminum sulfate production is used in the paper-making. And paper production and water treatment together occupied more than 90% aluminum sulfate.
