PHOSPHATE EXPLORATION IN IRAN
first signs of the presence of Phosphate were initially reported
during the drilling of oil wells in southwest Iran during
1954.The National Geology Organisation programmed the
exploration of Phosphate in Iran from end of 1963. From 1975 to
1981 with the cooperation of the French Research Geology & Mines
(BRGM) the exploration of phosphate rocks was started in
Iran. With the forming of Exploration Plans throughout
Iran in 1982, a systemic exploration of phosphate was
accomplished till 1993, resulting in indtroducing 27 potential
phosphate reserves throughout Iran with a total deposits of 630
million tons with an average grade of 8.5% of P2O5
Igneous (about 30 million tons) were identified by the Geology
Organisation of Iran of which most of these minerals
have gone through exploration and semi-comparisons.
Dressing which in the past for processing phosphate rocks
all the abovementioned minerals (in laboratory comparison
or semi-industrial) were performed showed that the Esfordi
Phosphate is the most feasible.
Phosphate with signs of Igneous due the high grade of P2O5
and open pit being of the mine and the low costs of the
exploration, it was considered as economical during that time.
