Sulfuric acid overflowed during a 15 August shutdown at Mosaic's unit in Industrial District 3, located in the Brazilian city of Uberaba.
Mosaic, which is headquartered in Minnesota and is one of the world's largest fertilizer producers, said there were no injuries and that the area in which the accident occurred was immediately isolated. The material neutralization process prevented leakage outside the facility.
The overflow happened two days after Mosaic's new Center for Disclosed Solutions in Uberaba opened.
Sulfuric acid is the element used in the phosphate rock synthesis. The result is sulfate compounds largely used in fertilization.
