Iron and Manganese Removal

Iron and Manganese Removal

Iron (Fe) and manganese (Mn) can be present in water in one of three basic forms: 1. Dissolved: ferrous (Fe2+) and manganous (Mn2+) 2. Particulate: ferric (Fe3+) and manganic (Mn4+) states 3. Colloidal: very small particles (difficult to settle and filter).

Smelting Wikipedia

Smelting Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a .
