Iron removing Principles and applications Nobel Srl

Brief description of the process. Iron can be contained in water as a dissolved matter or as a precipitate suspended. Obviously, the removal of suspended iron, normally consisting of ferric hydroxide, is not very complicated; it can be made by mean of a common mechanical filtration (mechanical sediment filters, sand dual media filters).

Iron removal from Turkish quartz sand by chemical leaching

The bioleaching of iron oxides by Aspergillus niger resulted in removal of 47. 70% of the total iron in the quartz sand, and suggested that this strain has not a good ability to remove iron impurities from quartz sand in comparison with chemical leaching. The iron content decreased from 0.315% Fe2O3 to 0.164% Fe2O3 in the bioleached quartz sand.
