The iron found in iron ores are found in the form of iron oxides.Iron - Manufacturing process related to the specified,,Iron powder via electrolysis . The manufacture of iron powder by electrolysis is a batch process. The anodes are usually made of iron or low carbon steel. The electrolyte of the cell consists of a sulphate solution (temperature 50°C). Pure iron is deposited as a brittle lightly adhering sheet on the cathodes. After washing, drying, andIron processing - Iron making | Britannica,Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
