The paper presents a method for deep iron removal from needle antimony by fire refining;where,by using phosphate as iron removal agent under oxidizing atmosphere,the iron in the refined antimony can be reduced to less than 50ppm.

Comparison between two kinds of iron removal techniques for steam condensed water;

Full-scale experimental study on iron removal from groundwater by fiber filtering media;

Application of basic zinc carbonate in iron removal of zinc sulfate solution

Study on deferrization and decontamination of silica sand in Dongshan County of Fujian Province;

Through the magnetic separation,acidwashing,sieving,reducing bleaching deferrization,the whiteness of product can be improved,and the reaction mechanism and charging system discussed.

Aiming at some defects and shortages existing in conventional deferrization processes,such as jarosite,goethite and spray processes,in zinc hydrometallurgy process and using new movements abroad for reference,the study on new technology for removing iron by phosphate has been carried out and satisfactory results have been achieved.
