Bu çalışmada, vanadyumun potansiyel bir vanadyum kaynağı olan silis kumundan özütlenmesinde organik asitlerin liç performansı araştırılmıştır. Çalışma kapsamında kullanılan silis kumu numunesi İstanbul Şile' de faaliyet gösteren özel bir madencilik şirketine ait silis kumu zenginleştirme tesisinden alınmıştır. Deneysel çalışmalar kapsamında, ayrıntılı karakterizasyon testleri ile organik ve inorganik asitlerle liç testleri gerçekleştirilmiş ve vanadyum için optimum ekstraksiyon koşulları belirlenmiştir. Elde edilen sonuçlar vanadyum ekstraksiyonu için en iyi sonucun hidroflorik asit ile elde edildiğini göstermiştir. Vanadyumun ekstraksiyon verimi, 2 saatlik liç süresi, 800 kg / ton HF miktarı ve 40oC pülp sıcaklığı optimal liç koşulları altında %76 olarak gerçekleşmiştir. Öte yandan, organik asitler arasında en iyi sonuçlar oksalik asit ile elde edilmiştir. Vanadyumun ekstraksiyon verimi, 2 saatlik liç süresi, 200 kg / ton oksalik asit miktarı ve 40oC pülp sıcaklığı optimal liç koşulları altında %50 olarak gerçekleşmiştir.

In this study, performance of organic acids in the extraction of vanadium from silica sand, a potential vanadium source, were investigated by leaching method. Silica sand samples used in this study was obtained from a silica sand beneficiation plant operating in Istanbul, Turkey. In the context of experimental studies, detailed characterization tests and leaching tests with organic and inorganic acids were performed on the representative samples obtained from the desliming unit of the plant, and the optimum extraction conditions for vanadium were determined. The obtained results showed that the best result for vanadium extraction was obtained with hydrofluoric acid. The extraction efficiency of vanadium was found to be 76% under optimal leaching conditions of 2 h of leaching time, 800 kg/ton of HF amount and 40oC pulp temperature. On the other hand, the best results among the organic acids were obtained with oxalic acid. The extraction efficiency of vanadium was found to be 50% under optimal leaching conditions of 2 h of leaching time, 200 kg/ton of oxalic acid amount and 40oC pulp temperature.
