Sulfuric acid at center of new multi-function complex in Turkey
Eti Bakır recently commissioned a brand-new combined roasting/leaching/ fertilizer complex in Mazıdağı, the site of an abandoned phosphate mine in southwestern Turkey. The new facility uses the onsite phosphate along with pyrite concentrate transported from another site to produce base metals and phosphate-based fertilizers. The sulfuric acid unit is central to the process, capturing SO2 from pyrite roasting, delivering calcine feedstock to the leaching function, and supplying acid to feed both the leaching and fertilizer processes. The unit also generates enough steam to power the entire complex.
