The Processes of Iodine Extraction

Adopting Air-blowing process, which has high extraction efficiency, simple and stable operation, easy automatic control, and low operation costs.

The technical process mainly consists of two parts: iodine extraction process and iodine refinement process.

The iodine extraction process mainly includes several key stages: iodized brine acidification, chlorine oxidation, air blowing, and absorption.

The refinement process uses the absorption liquid from circulation absorption tower as the raw material for iodine refinement, and the main stages include dissociation, lavation and filtration, steam distillation, and crushing and packing.

• Based on the basic data and varying requirements of different plants, the process needs to be professionally customized and appropriately adjusted.
