Product Information

Known as Darou, after the name of the community in which the facilities were installed (Darou Khoudoss), ICS's Acid Site is a chemical complex made up of two adjacent phosphoric acid production units, with a total production capacity of 660 000 tons of P2O5 per annum.


The facilities, located near the Taïba mine (100 km from Dakar) have enabled Senegal to develop large-scale inorganic chemistry and locally process a growing share of its phosphate production into phosphoric acid (54% P2O5), thus creating a sizeable added value. Practically all of this phosphoric acid production (one part is reserved to Fertilizer site ) is exported to our Indian partners IFFCO.


This industrial activity has also enabled ICS to boost a variety of other sectors in the country (transportation - repairs - services - trade - water and power supply - etc.)



The Darou1 and Darou2 plants, with a production capacity of 330 000 tons of P2O5 each, were built along the same lines and include:


•a sulphuric acid production shop, using imported solid sulphur,

•general services and utilities that ensure the plant's energy self-reliance,

•a phosphoric acid production shop, where the acid is produced through a controlled sulphuric acid attack on the phosphate.


The plants share a large machinery maintenance department to ensure good coverage of the facilities.


In the near future, optimization of electrical power production due to the doubling of Darou facilities should allow us to become completely energy self-reliant at the neighbouring Taïba mine as well.
