Extraction of Iron. It can be easily separated out of molten iron. The iron manufactured in Blast Furnaces contain about 3 4 % of Carbon and smaller quantities of many other impurities such as sulfur, Silicon, etc. This is called Pig Iron. It is a hard but brittle metal and the impurities severely hamper its strength.
This method of extraction works because carbon is more reactive than iron, so it can displace. iron from iron compounds. Extracting a metal by heating with carbon is cheaper than using electrolysis.
The method is based on the adsorption and extraction of iron (III) after passing on inorganic/organic hybrid adsorbent in a column with detection by ame atomic absorption spectrometry (FAAS). The optimum conditions for adsorption were evaluated by changing various parameters such as initial pH of the solution, contact time, adsorbent dose
