Abstract (2. Language): 
Acidic leaching of mechanically activated manganese ore from Denizli – Tavas was investigated. The ore was activated mechanically in a planetary mill and the amorphisation in manganese structure was analyzed with X-ray diffraction. The parameters in acidic leaching of the ore were milling time, acid concentration and time. All experiments were performed at 25°C with solid to liquid ratio: 1/10. The activation procedure led to amorphization and structural disordering in manganese ore and accelerated the dissolution of manganese in acidic media.

Abstract (Original Language): 
Mekanik aktive edilmiş Denizli – Tavas bölgesi mangan cevherinin asidik liçi incelenmiştir. Cevher bir gezegensel değirmende aktive edilmiş ve mangan yapısındaki amorflaşma X-ışınları difraksiyonu ile analiz edilmiştir. Cevherin asidik liçindeki parametreler öğütme süresi, asit konsantrasyonu ve zamandır. Bütün deneyler 25°C de ve katı/sıvı oranı 1/10 olacak şekilde gerçekleştirilmiştir. Aktivasyon işlemi mangan cevherinin yapısında amorflaşmaya ve yapısal düzensizliğe neden olmuş ve manganın asidik ortamdaki çözünürlüğünü hızlandırmıştır.
