With the aim of being self-sufficient in supplies of potassium chloride (KCl), raw material for the production of potassium nitrate, SQM began operations in the Atacama Salt Flats. The initial investment included the construction of a plant for potassium chloride and potassium sulfate. Currently the business line of potassium includes the sale of these two potassium fertilizers.The main sources of potassium that exist in the market for use in fertilizers are: Potassium chloride (KCl), potassium sulfate (K2SO4) and potassium nitrate (KNO3). Of these three, potassium chloride is the most commonly used worldwide. SQM is a low-cost producer with the flexibility to produce these three sources of potassium based on market needs.

Industrial Chemicals

We have proven experience producing and selling nitrates, potassium chloride, boric acid and magnesium chlorides. Potassium nitrate and sodium nitrate are the raw materials for solar salts, which are essential to the functioning of solar thermal power plants; and magnesium chloride hexahydrate—known as bischofite—is used for effective dust control and de-icing on roads.
