The possibility of improving the flotation efficiency of Turkish bituminous coal fines by a split feed flotation scheme was investigated in comparison with conventional single-stage flotation. Coal samples collected from the <0.6 mm fines treatment circuit of an operating washery were used in laboratory batch tests simulating single-stage and split feed flotation circuits. Collector (kerosene) and frother (iso-octanol) additions were used as major test variables. Results were evaluated on the basis of the efficiency index for metallurgical optimization purposes. Split feed flotation appeared to be a better alternative scheme from the metallurgical point of view. Copyright (C) 1996 Elsevier Science Ltd.

Modelling of ECBM recovery from Amasra Coalbed in Zonguldak Basin, Turkey Sınayuç, Çağlar (2018-01-01) Bartin-Amasra coal field was found convenient for enhanced coalbed methane (ECBM) recovery among the other fields in Zonguldak Coal Basin, Turkey. The lithologic information were examined and the depths of the coal seams and the locations of the wells were visualized to perform a reliable correlation between 63 coal layers existed in the area. The initial methane in place found in the coal layers both in free and adsorbed states were estimated using probabilistic simulations resulted in possible reserve (P1...
An Investigation of landslide at KM: 12+200 of Artvin - Savsat junction - Meydancık provincial road Topsakal, Ebru; Topal, Tamer; Department of Geological Engineering (2012) The purpose of this study is to determine the most suitable remediation techniques via engineering geological assessment of the landslide that occurred during the construction of Artvin-Şavşat Junction - Meydancık Provincial Road at Km: 12+200 in an active landslide area. For this purpose, the geotechnical parameters of the mobilized geological material which is colluvium along the sliding surface were determined by back analyses of the landslide at three geological sections. The landslide were then modeled...
Beneficiation of Himmetoglu oil shale by flotation as a solid fuel substitute. Part 1. Materials characteristics and flotation behavior Altun, Naci Emre; Hwang, JY; Bagci, AS (2006-01-01) In this study, the processing of Himmetoglu oil shale from Bolu, Turkey, by flotation techniques was investigated for the possibility of achieving a clean solid-fuel substitute. The surface characteristics and mineral content of Himmetoglu oil shale were determined using mineralogical, XRD, and FIR analysis. The flotation response of the sample was tested with several nonionizing collectors and a variety of ionizing collectors belonging to both cationic and anionic groups. The effects of collector dosage an...
An Experimental study on the pool fire burning characteristics of n-heptane and ethanol in the tunnels Yamalı, Tevfik Uluç; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2015) The road and railway tunnel disasters in recent decades drew the attention of fire safety engineers. The effects of mechanical ventilation, tunnel geometry, physical and chemical properties of fuel on fire characteristics such as heat release rate, smoke temperature distributions along the tunnel and burning rate are experimentally examined on full scaled, large scaled and reduced scaled tunnel models. Although there are many studies on the effects of conventional fuels like gasoline and diesel, the blended...
An analysis of deformation behaviorof Muratlı asphalt faced rockfill dam Ünsever, Yeşim Sema; Özkan, M. Yener; Department of Civil Engineering (2007) In this study, settlement and seepage behavior of Muratlı Dam, which is the first asphalt faced rockfill dam in Turkey, is investigated for the “end of construction” and “reservoir impoundment” loading conditions. Two dimensional plane strain finite element analyses are carried out in order to determine the total stresses, displacements and pore water pressures. Hardening soil model is used in order to represent the non-linear, inelastic and stress dependent behavior of rockfill material. Material model par...
