AYVACIK-TUZLA BÖLGESİNDEKİ JEOTERMAL KAYNAKLARDAN METAL/MİNERAL KAZANIM OLANAKLARI

Öz

   Bu çalışmanın amacı Biga Yarımadası'nda ticari olarak önem atfedebilecek metal ve mineral içeren jeotermal sahaların jeolojik ve jeokimyasal sınırlarını tanımlayıp, sürdürülebilir bir geri kazanım teknolojisini özgün bir fizibilite analizi ile bütünleştirerek değerlendirmektir. Biga Yarımadası özelindeki jeotermal kaynakların fiziksel özellikleri ve kimyasal kompozisyonları incelendiğinde, yüksek sıcaklığa (T>60°C) ve nispeten asidik pH değerlerine sahip kaynakların yeterli miktarda ticari değere sahip materyali sağlayabileceği öngörülmektedir. Gerçekleştirilen pilot ölçekli fizibilite analizine göre Tuzla jeotermal sahası temel alındığında jeotermal akışkandan günde yaklaşık 22 Kg Li metali üretebileceği hesaplanmıştır. 10 yıllık bir işletme süresi göz önüne alındığında fayda-maliyet oranı (F/M) 3,71 olarak belirlenmiştir. Birden büyük olan bu oran yapılacak geri kazanım yatırımının karlı olduğunu işaret etmektedir.

METAL/MINERAL RECOVERY FROM GEOTHERMAL RESOURCES IN AYVACIK-TUZLA REGION

Abstract

   The aim of this study is to identify and analyse the prospective areas in the Biga Peninsula in terms of geothermal waters as a source of commercially valuable materials. Identified potential sources will be evaluated integrating a sample cost analysis for a pilot reclamation process. The review of the geochemistry of geothermal resources in the Biga Peninsula indicates that geothermal waters with high temperature (T>60°C) and slightly acidic pH values will yield sufficiently quantifiable dissolved commercial element concentrations. In this respect, pilot feasibility analysis showed that a geothermal fluid representing Tuzla geothermal resources could produce approximately 22 Kg Li metal per day. Benefit-cost ratio was calculated to be 3.71, showing that such an investment is profitable for a ten years of operation
