Abstract

Bu çalışmada, Kastamonu Hanönü bakır cevheri üzerinde, deniz suyu varlığında Acidithiobacillus ferrooxidans bakterisi kullanılarak biyoliç deneyleri gerçekleştirilmiştir. Numunenin karakterizasyonu XRD, XRF ve SEM analiz yöntemleri ile yapılmıştır. Biyoliç deneyleri sırasında, 360 saatlik test süresi boyunca bakteri konsantrasyonu, pH, bakır ve demir konsantrasyonları izlenmiştir. Sonuçlar, uygun bir deniz suyu oranının bakır geri kazanımını önemli ölçüde artırdığını ve katı-sıvı oranının bu süreçte kritik bir rol oynadığını göstermiştir. %30,00 deniz suyu varlığında ve %7 katı oranında, maksimum %81,43 bakır geri kazanımı elde edilirken, deniz suyu olmadan bu oran yalnızca %71,02 olarak gerçekleşmiştir. Bu çalışma, deniz suyunun hem çevresel hem de ekonomik faydalar sunan alternatif bir çözücü ortamı olarak potansiyelini vurgulamaktadır. Ayrıca, biyoliç yönteminin çevre dostu ve verimli bir süreç olarak uygulanabilirliği vurgulanmaktadır.

Influence of Seawater Addition on the Bioleaching Process of Chalcopyrite Ore Using Acidithiobacillus ferrooxidans

Abstract

In this study, bioleaching experiments on Kastamonu Hanönü copper ore were conducted using the bacterium Acidithiobacillus ferrooxidans in the presence of seawater. The characterization of the sample was performed using XRD, XRF, and SEM analysis methods. During the bioleaching experiments, bacteria concentration, pH, copper and iron concentrations were monitored over the 360-hour test period. The results demonstrated that an appropriate proportion of seawater significantly promoted copper recovery, with the solid-to-liquid ratio playing a key role. A maximum copper recovery of 81.43% was achieved in the presence of 30.00% seawater, 7% solid rate compared to only 71.02% in its absence. This study highlights the potential of seawater as an alternative solvent medium, offering both environmental and economic benefits. Moreover, the findings emphasize the applicability of the bioleaching method as an environmentally friendly and efficient process.
