Esfordi Phosphate Complex

Hamidreza Askari, Managing Director of Esfordi Phosphate Complex

1. About the Complex

1.1- Esfordi Phosphate Industrial and Mineral Complex with a capacity to produce phosphate concentrate and iron concentrate has highest quality phosphate in the country. Located 35 km northeast of the city of Bafq and 155 km of Yazd Province, the plant produces 62,000 tons of phosphate concentrates and 23,000 tons of iron concentrates as byproduct, annually.

1.2- The contract for the basic and detailed engineering plan of the mine was signed with the British Company Denver in 1369 (1990/91) and construction operations and building of the processing factory was launched in 1373 (1994/5) and was put into operation in 1378 (1999/2000).

2. Products

2.1- Phosphate concentrate with an alloy of P205%36.5+-1

2.2- Iron concentrate with an alloy of Fe%60+-1

3. Phosphate Consumption

3.1- Phosphate is used 85% in production of different fertilizers, 8% in animal feed and human food supplement, 5% for industrial purposes and 2% in specific chemical substances. The most use of phosphate is in production of phosphate fertilizers and industrial and oral phosphoric acid for use in food and medicine industries such as: vegetable oil, sugar production from sugar cane, beverage industry, pharmaceuticals and detergents, paint and resin, textile industry, oil industry, military industry, etc.

3.2- The main consumption of Esfordi concentrate phosphate is in domestic industry for the production of different types of fertilizers such as simple super phosphate (SSP), triplet fertilizer (TSP) and diammonium phosphate (DAP) or monoammonium phosphate (MAP) and production of industrial phosphoric acid (H3PO4).

3.3- The most common method to use phosphate rock is its conversion into phosphoric acid and then its consumption in the related industries. In order to benefit from the investment and the capacity of the private sector in line with increasing productivity for realizing the Resistance Economy program, production and employment, production of phosphoric acid, etc., the complex was assigned to Khatam al-Anbia Construction Headquarters as of December 22, 2016 in the course of legal formalities within the framework of leadership. 

3.4- Domestic Companies consuming the product of Esfordi phosphate are: 1- Garmab Shimi Company 2- South Arkan Shimi Company 3- Lian South Phase Company 4- Bafq Poison and Fertilizer Company 5- Tamodan Kerman 6-Kimiya Royesh Mehr Pars Company, etc.

4. Introduction of Manufactured Products for Export and Volume of Exports

Esfordi deposit has the following special features that are competitive in global markets:

4.1- Possibility of producing phosphate concentrate with high alloy upon the client’s demand (for example: production and delivery of 2,000 tons of  40% concentrate to Prion Company of Belgium in 1379-80 (2000/01) upon an order by the aforementioned company.

4.2- Another important feature of Esfordi deposit is the content of 1.2% of rare earth elements, including cerium (Ce) - yttrium (Y) - neodymium (Nd) and lanthanum (La), which is used in military, defense and airplane industries as well as spaceships, wind turbines, and solid and resistance alloys.

4.3- Lower percentage of cadmium (a harmful element for humans and plants) in the produced phosphate concentrate (ppm 10-5) is one of the specific characteristics of the Esfordi phosphate (its maximum limit has been set at 25 mg in imported phosphate fertilizers).

4.4- Export of phosphate totaled about 70,000 tons during the years 2001, 2004, 2007, 2008 to Belgium, Spain, India and Pakistan.

5. Opportunities to Attract Investment

5.1- Investing in phosphoric acid production from manufactured phosphate concentrate

5.2- Investment in production of phosphoric acid from low-grade green extracted stones (unprocessed)

5.3- Investment in extraction of rare earth elements

5.4- Investment in the phosphate exploration section

6. Most Important Measures and Performance of the Last Five Years

6.1- Five-year performance in production and sales

6.2- Launching pilot plant for the extraction of rare earth elements and conducting pilot tests

6.3- Assigning the complex to the private sector in line with the implementation of general policies of Article 44 of the Constitution with an aim of attracting capital and making investment and development for the construction of acid phosphoric plant or another final product to the Khatam al-Anbia Construction Headquarters

6.4- Receiving three-star productivity emblem award from Iranian Mines and Mining Industries Development and Renovation Organization (IMIDRO)

6.5- Extension and obtaining ISO 9001: 2015, ISO 14001: 2015 and OHSAS 18001: 2007 certificates.

7. Membership in International Consortiums

7.1- Extraction of rare earth elements with foreign consortiums using modern methods such as nano and bio-leaching.

7.2- For example, joining the consortium of mining phosphate rock producers in line with investment in exploitation and extraction of more than 600 million tons of discovered deposits in Iran via new methods.

7.3- Participation in the consortiums of Chinese and Russian companies in line with making investment in production of phosphoric acid from the low-grade green rock deposits of Esfordi or the known reserves of the country by using the IHP method which has good technical knowledge in this regard.

8. Prospects and Trends of Global Market for Chemical Fertilizers by 2019

The amount of demand for enriched fertilizers in 2014 exceeded 184.67 million tons, which increased to about 186.6 million tons in 2015. If this figure is to increase continuously by 1.6% per year, it would reach 199 million tons by 2019.
