Özet:

 In this study, solid waste clays from the Emet Concentrator Plant were used. With the data obtained from the characterization tests, it was decided to work with the sample fraction with a Li grade in the range of 1942-2035 ppm, which is below 0.5 mm grain size. Clay samples and salt mixtures are blended at different rates. In the first stage, the leaching effect of salt type and ratio was investigated, and in the second stage, the roasting time and temperature were investigated. The effectiveness of the parameters used in the roasting study was evaluated by lithium extraction studies. In the third phase of the study, leaching, the study was completed by considering the H2SO4 concentration and leaching time. With the processes carried out, first of all, the mixture obtained by blending the samplesalt mixture ratio of 11 and between the salts in the ratios of NaCl 0.6-CaCl2 0.4; Result of roasting at 900 C for 1 hour, a roasting efficiency of 77.26 Li was obtained. Then, by leaching the roasted material in the presence of 0.4M H2SO4 for 1 hour, the leaching efficiency was determined to be 89.61 Li.

 Bu çalışmada, Emet konsantratör tesisi katı atık killeri kullanılmıştır. Karakterizasyon testlerinden elde edilen veriler ile 0.5 mm tane boyutu altında kalan, 1942-2035 ppm aralığında Li tenörlü numune fraksiyonu ile çalışmaya karar verilmiştir. Kil numunesi ile tuz karışımları, farklı oranlarda harmanlanarak; ilk aşamada tuz türü ve oranının, ikinci aşamada kavurma süresi ve sıcaklığının liçe etkisi ölçülmüştür. Kavurma çalışmasında kullanılan parametrelerin etkinliği, lityum ekstraksiyon çalışmaları ile değerlendirilmiştir. Çalışmanın üçüncü aşaması olan liç uygulamasında ise, H2SO4 konsantrasyonu ve liç süresi dikkate alınarak çalışma tamamlanmıştır. Gerçekleştirilen işlemlerle öncelikle, Numunetuz karışım oranı 11, tuzların ise kendi arasında NaCl 0.6-CaCl2 0.4 oranlarında harmanlanmasıyla elde edilen karışımın; 900 C sıcaklıkta 1 sa. kavrulması sonucu 77.26 Li kavurma verimi elde edilmiştir. Daha sonra, kavrulmuş malzemenin 0.4M H2SO4 varlığında 1 sa. liç işlemine tabi tutulması ile liç verimi 89.61 Li olarak tespit edilmiştir.
