Refined New Technology and Its Application Based on the Phosphate Rock Associated Iodine

Abstract

Iodine associated with phosphate rock is an important part of iodine resources, thus technology development and comprehensive utilization of recycling and refining of iodine associated is significant. From the process of phosphate rock processing recycling ω<95% of the crude iodine need refined into a w of 99.5% or more pure iodine. This paper briefly introduces the phosphate rock associated iodine recycling method, is described in detail sublimation method refining technology and operation method of the iodine analyzes the problems existing in the production and puts forward corresponding solving measures.
