Iron (Fe) used to produce coagulants and flocculants, can come from various sources such as:
- pickling liquor
- mill scale or scrap from the steel industry
- copperas or ferrous sulphate, from the titanium dioxide production
LKAB Minerals’ MagnaChem is a high grade, natural alternative iron source to these recycled and less pure products.
