Beryllium Extraction and Beneficiation
Unlike aluminum, it resists corrosion by salt water, etc. Its rate of expansion with heat is the same as that of cast iron. It alloys easily with aluminum. An alloy of beryllium 70% and aluminum 30%, is one-fifth lighter than aluminum, and resists corrosion much better. In tensile strength it greatly exceeds duralumin.

Production of Red Iron Oxide (Mining of Mineral Ore with …
Crude Iron is produced from iron ore. Iron ore is extracted from rock and minerals. These ores are usually wealthy in iron oxide (Fe2O3) and differ in color from grey, deep yellow, rusty red to deep purple. Iron is found within the variety of goethite (FeO (OH)), siderite (FeCO3), limonite (FeO (OH).n (H2O)), hematite (Fe2O3) and magnetite (Fe3O4).
