Abstract
A rapid method for the efficient extraction of iron(II) from rocks and minerals is described. With this method oxidation is minimised and batch working is possible. The silicate is decomposed in sealed plastics bottles and the iron(II) determined titrimetrically by redox titration or, for small amounts of minerals, colorimetrically by means of 2,2′-bipyridyl.Keywords
