Since its start has continued to develop and grow both technically and qualitatively in the following phases:
1958 – 1963: A sulfuric acid production unit of 50 tons / day and a simple superphosphate production unit of 300 tons / day.
1964 – 1969: A sulfuric acid production unit of 100 tons / day and a sulfuric acid production unit of 300 tons / day.
1970 – 1973: A phosphoric acid production unit of 300 tons / day and a granulation unit of 800 tons / day to produce triple superphosphate (TSP).
1974 – 1978: A phosphoric acid production unit of 300 tons / day and an aluminum sulphate production unit of 60 tons / day.
Since 1997: A sulfuric acid production unit of 1,500 tons / day, an extension of the phosphoric acid production units allowing to obtain an additional 200 tons / day of P2O5 and a modification of the granulation unit allowing to obtain 100 tons / day of Mono Calcium Phosphate.
