SQM's Nitrates Iodine Division will use seawater in its production

The project is aimed at adding new mining areas to boost production, while adding the use of seawater to the production process, which will double iodine production capacity. These 900 liters per second of seawater will allow the plant to produce around 23,000 tons of iodine without using inland water for this increase.
