SULPHUR

Sulphur (S) is an essential plant nutrient. It contributes to increase crop yield by providing direct nutritive value, as well as indirect nutritive value by enhancing soil productivity and improving use efficiency of other key nutrients (nitrogen and phosphorus).

Sulphur is the main source for sulphuric acid production, the world’s most used chemical. In the fertilizer industry, sulphuric acid is mainly used to produce phosphates but also nitrogen, potassium and sulphate fertilizers. In the metals industry it is used for mineral ore leaching to produce essentially Copper, Nickel and Zinc.

Sulphur is naturally present in the environment and was mined for many years, however most of today’s elemental sulphur is produced as a by-product from oil refining and gas processing plants.
