This study presents the results of the application of the laboratory gravity-recoverable-gold (GRG) determination procedure on a Turkish gold ore using a Falcon concentrator. The study had two major goals; as investigating the compatibility of Falcon concentrator for GRG procedure (which was originally developed for Knelson concentrator); and finding out the gravity recoverable gold content in Gumushane/Mastra gold ore. It was seen that a concentrate enriched in Au content could be successfully achieved: After the first stage a product with an Au grade of 41.09 mgAu/tonne at % 10.95 fractional gold recovery at the first stage of the procedure. Au content in the concentrate increased to 98.84 mg after the second stage and finally 59.74 mg Au was obtained by the third stage. As a result of the application, it was found that the GRG content of Gumushane/Mastra gold was 48.28%, corresponding to a significant potential for obtaining an Au-enriched preconcentrate.

THE USE OF CONTINUOUS CENTRIFUGAL GRAVITY CONCENTRATION IN GRINDING CIRCUIT. MODIFIED APPROACH FOR IMPROVED METALLURGICAL PERFORMANCE AND REDUCED GRINDING REQUIREMENTS
Altun, Naci Emre; Klein, Bern (2015-01-01)
The use of centrifugal gravity concentration in the closed-grinding circuit of a gold-containing massive sulphide ore was tested on classifier underflow and overflow. A continuous Knelson CVD6 was retrofitted to the hydrocyclone underflow for recovery of Au and Pb at a coarser feed size. The objective of treatment of overflow was recovering unliberated Au prior to flotation. The tests were performed in actual operating conditions at Nyrstar's Myra Falls Mine. The results of the tests on the cyclone underflo...

Ekici, Selda (Ankara University - Faculty of Language and History-Geography, 2020-12-15)
Türkiye'de 2000 yılı ve sonrasında oluşturulan ulusal bilim-teknoloji politikalarında bilgi yönetimine yaklaşımı ve bakış açısını ortaya koymak amacıyla gerçekleştirilen bu çalışmada, bilgi yönetimi kavramının çerçevesi “bilgi kaynakları, bilgi hizmetleri, bilgi sistemleri ve bilgi altyapısı” unsurlarını içeren bilgi politikası bağlamında çizilmiş, bilginin elde edilmesi, bilimsel ve teknik yöntemlerle düzenlenmesi ve sunulması anlamıyla ele alınmıştır. Araştırma kapsamında belirlenen amaca ulaşabilmek...
The effect of chitosan-based edible film and high hydrostatic pressure process on the microbiological and chemical quality of rainbow trout (Oncorhynchus mykiss Walbaum) fillets during cold storage (4 +/- 1 degrees C)
Guenlue, Ali; SIPAHIOGLU, Sinem; Alpas, Hami (Informa UK Limited, 2014-01-02)
The objective of this study is to determine the changes in the chemical and microbiological quality of fresh rainbow trout (Oncorhynchus mykiss Walbaum) fillets during storage at 4 +/- 1 degrees C as a result of chitosan-based edible film coating, vacuum packaging and high pressure application processes. Chemical (pH, total volatile basic nitrogen and thiobarbituric acid index) and microbiological (total mesophilic and total psychrophilic microorganism) shelf life analyses were carried out in 4-day interval...
In-situ combustion laboratory studies of Turkish heavy oil reservoirs
Bagci, Suat; Kök, Mustafa Verşan (Elsevier BV, 2001-12)
The purpose of this research was to perform dry and wet forward combustion experiments for Turkish heavy oil reservoirs (Raman, Adiyaman and Çamurlu and Bati Kozluca) under different experimental conditions. In the experiments, a vertical tube was packed with crushed limestone and saturated with crude oil and water. It was observed that peak temperatures were higher when stabilized combustion was achieved and decreased as the combustion front approached the outlet end of the tube. In wet combustion experime...
The Use of multimetric framework in calibrating the HBV model
Sürer, Serdar; Akyürek, Sevda Zuhal; Yılmaz, Koray Kamil; Department of Geodetic and Geographical Information Technologies (2015)
In this study, the HBV model is applied on the upper Euphrates basin in Turkey. Individual sensitivity of the parameters is analyzed by calibrating the model using the Multi-Objective Shuffled Complex Evolution (MOSCEM) algorithm. The calibration is performed against snow cover area (SCA) in addition to runoff data for the water years 2009, 2010, 2011 and 2012. Detailed validation studies are also performed for the snow products namely snow recognition (H10) and snow water equivalent (H13) over Turkey and A...
