Cobalt. The greatest production of cobalt entails the metallic form used in the formation of cobalt super alloys. The two valance states are cobaltous (II) and cobaltic (III) and the former is the most popular valance used in the chemical industry. Its presence has also been spotted in the sun and in meteoric iron.

the hydrogen ion content of the water system is increased (, pH decreases). If cation resin is processed in the sodium form, however, positively charged ions are replaced with a sodium ion, and the pH value increases. Such a means is being employed in a stator cooling system at an Eskom generating facility in South Africa [13].

Metallic iron can be economically extracted from rocks and minerals, often referred to as iron ores. These ores are typically high in iron oxides. They vary in color. Iron itself is found in one of the following forms: magnetite (Fe304), hematite (Fe203), goethite (FeO(OH)), limonite (FeO(OH).n(H20)), or siderite (FeC03). Pig iron, one of the necessary raw materials in making steel, is comprised partially of iron ore.
