Fosfat cevheri, kritik öneme sahip hammaddelerin ekonomik önemini ve tedarik riskini vurgulayan
Avrupa Komisyonu raporuna göre, tüm canlılar (bitkiler, hayvanlar ve insanlar) için en kritik
hammaddelerden biridir. Bu sebeple; düşük tenörlü fosfat cevherinin değerlendirilmesi önem arz
etmektedir. Bu çalışmada, fosfat cevherinin içerdiği karbonatlı minerallerin (kalsit ve aragonit)
selektif olarak uzaklaştırılması kalsinasyon-sakkaroz liçi yöntemleri uygulanarak araştırılmıştır.
Çalışmada kullanılan cevherin karakterizasyonu X-ışını difraksiyon (XRD), termogravimetrik
(TG) ve X-ışını flüoresans (XRF) spektroskopisi ile belirlenmiştir. Kalsinasyon sıcaklığı (750, 850
ve 900 ˚C) ve süresinin etkisi (15, 30, 60, 90 ve 120 dk) incelenmiştir. Sakkaroz ile yapılan liç
işlemlerinde ise karıştırma hızı (0, 150, 300, 450 dev/dk, sakkaroz konsantrasyonu (0, 0,25, 0,50,
1, 1,50 ve 2 M) ve liç süresinin (15, 30, 60, 120, 180 ve 240 dk) etkileri ortaya konmuştur. Sonuç
olarak; kuvars içeriğinin yüksek olması, kalsinasyon işlemi sırasında istenmeyen CaSiO3 minerali
oluşmuş olsa da karbonatlı minerallerin selektif olarak cevherden uzaklaştırılması sağlanmıştır.

Phosphate ore is one of the most critical raw materials for all living things (plant, animal, and human),

according to the European Commission report which explains the importance of economical and

supply risk of raw materials. Therefore, the evaluation of low-grade phosphate ore is of vital

importance. In this study, the selective removal of carbonate minerals (calcite and aragonite) from

phosphate ore was investigated by using calcination-sucrose leaching processes. The sample

used in this study was characterized by X-ray diffraction (XRD), Termogravimetric (TG), and

X-ray fluorescence (XRF) spectroscopy, respectively. The effect of calcination temperature (750,

850 and 900 ˚C) and calcination duration time (15, 30, 60, 90, and 120 min) were examined.

Leaching tests were performed with various sucrose concentrations (0, 0.25, 0.50, 1, 1.50, 2

M) at different stirring speed (0, 150, 300, 450 rpm) during several times (15, 30, 60, 120, 180

and 240 min). As a result, the selective removal of carbonate minerals from phosphate rock was

provided although unwanted CaSiO3 mineral was formed during the calcination process due to

its high quartz content.
