In a company brochure, STG lists Iran as among those countries where “it has implemented [its] largest infrastructure projects.”
“Russian company STG has signed a contract with Iranian Mines and Mining Industries Development and Renovation company, known as IMIDRO, to produce alumina from Nepheline syenite, Iran's IRNA news agency quoted IMIDRO director Mehdi Karbasian as saying on April 7. Nepheline syenite is used in glass making, ceramics and in pigments and fillers. STG will handle the production and at a later stage transfer the project to the Iranian side, which refused to give the project to any other specialists. ‘Based on the contract, the Russian company will implement the project in 3-4 years,’ Karbasian said.” (Trend, “Russian company inks mineral contract with Iran,” 4/7/14)
