Dissolution Kinetics of Calcinated Manganese Ore in Acetic Acid Solutions

Öz

Bu çal mada, Denizli-Tavas yöresinden temin edilen mangan cevheri ilk olarak 700 oC de bir saat kalsine edildi. Kalsine mangan cevherinin seyreltik asetik asit çözeltileri içindeki çözünme oran üzerine s cakl k, kat /s v oran , reaksiyon süresi, kar t rma h z , tanecik boyutu ve asit konsantrasyonunun etkileri incelendi. Reaksiyon s caklkat /s v oran n n azalmas yla çözünme oran n n artt birinci mertebeden reaksiyon modeline uydu u ve reaksiyona ait aktivasyon enerjisi 25.51 kJ.mol-1 olarak hesaplanm t r
