   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

Öz

   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
