Refined New Technology and Application of Phosphate Rock Associated Iodine

Abstract:

Iodine is a world of scarce resources, and its characteristic is low yield, high price, wide uses. Production of iodine is≦800 t/a in our country, but demand of iodine is above 4000 t/a, so demand differences is big, about 80% of the iodine is importsed from countries such as Chile, Japan, turkmenistan^[1]. At present iodine in our country mainly rely on extracting from kelp, but iodine yields are low,owing to limited algae production, low technology, large waste of resources and high operating cost factors, it is difficult to meet the basic requirements of iodine in our country. However, phosphate rock in our country contains considerable associated iodine, so much attention are given to development of associated iodine resources and comprehensive utilization of phosphate rock.
