The mineralogical and technological study of gold ores and dressing products demonstrate the persistence of both the ores and products of their dressing, especially Floatation concentrates. The gold loss in the tails of Floatation beneficiation are primarily associated with the smallest size fractions less than 20 microns, which make up to 70\% of the total lost gold in the Floatation tails. It is obvious that increasing the extraction of gold by Floatation is directly linked to the development of the technologica...

(SGEM Scientific GeoConference, 2010, J. Paceagiu, I. Mohanu, C. Draganoaia)

Show more

The aim of the present research work is to investigate the possibility of adding a mixture of non-granulated blast furnace slag (NGBFS) and steel slag, two wastes resulting from metallurgical industry which underwent calcinations previously, in the raw meal for the production of Portland eco-cement clinker. For this purpose, the NGBFS and steel slag from ArcelorMitall Steel Galati were analyzed for chemical, mineralogical and heavy metals contents. Two samples of raw mixes were prepared, one with typically raw mat...

RULE-BASED MAMDANI-TYPE FUZZY MODELLING OF THERMAL PERFORMANCE OF WALL TYPES MOST USED IN RESIDENTIAL BUILDINGS IN TURKEY

(SGEM Scientific GeoConference, 2010, M. Tosun, K. Dincer, S. Baskaya)

Show more

In this study, simulation modelling of insulation layer (di), for residential buildings in 81 cities classified into four climatic regions in Turkey was. This stimulus model is constructed into Rule-Based Mamdani-Type Fuzzy Modelling (RBMTF) using input parameters (Uw, Te,Met, Te,TSE, Rwt, qTSE) and output parameter di described by RBMTF if-then rules. RBMTF has been designed using the MATLAB fuzzy logic toolbox.

SCATTERING OF ELECTROMAGNETIC WAVES AND PREDICTION REMARKS REGARDING MINING

(SGEM Scientific GeoConference, 2010, O. Yildirim)

Show more

A number of scattering and diffraction problems concerning semi infinite wave guides have been solved by many authors and for many years. Theoretical analysis of electromagnetic wave scattering and diffraction problems has been investigated extensively with regard to a number of scatterers which have physical and geometrical discontinuities. As is well-known, Sommerfeld introduced the exact solutions to the diffraction by a wedge by defining the idea of multiple-valued functions. His method is known as the Sommerf...

SEABED FEATURES FROM A SIDE SCAN SONAR SURVEY AT NORTH OF ANTIMILOS ISLAND

(SGEM Scientific GeoConference, 2010, A. Mitrousis)

Show more

The side scan sonar is the main tool for deep marine archaeology research but is also equaled significant in mapping of underwater geophysical features. Ancient and modern shipwrecks can be located with the correct translation of sonar records in conjunction with visual inspection. During a short but difficult side scan sonar survey (for documentary film purposes) in searching for the shipwreck HERAKLION (without results), at the sea area north of Antimilos island (South Aegean Sea, Greece), we recorded two intere...

SEDIMENT DISTRIBUTION PATTERN ALONG EASTERN PART OF THE IRANIAN MAKRAN SHELF, NORTHERN GULF OF OMAN

(SGEM Scientific GeoConference, 2010, H. Lahijani, M. Shah-Hosseini, M. Hosseindoost, A. NADERI Beni, P. Habibi, H. Bagheri, C. Morhange)

Show more

Surface and core sediment samples from the Iranian continental shelf of the Gulf of Oman have been studied using standard sedimentological techniques. Based on the grain size analysis of surface and core sediments, the silt fraction is the common sediment type in the Makran shelf. It ranges from 40\% up to 76\%. The amount of clay fraction varies from 19\% to 54\%. Sandy sediments appear in some cores up to 20\%. Mean content of organic matter and calcium carbonate in the sediments is around 1.75\% and 15.4\%, res...

SEISMIC PROPERTIES OF MARBLES FROM MUGLA REGION IN TURKEY

(SGEM Scientific GeoConference, 2010, A. Deliormanli, L. Burluni, B. Yavuz)

Show more

In this paper we report the experimental measurements of Vp-Vs on Triassic marble samples that are Mugla White and Aubergine from Mugla region. The measurements of P-S wave velocities were performed at room temperature and high confining pressure up to 300 MPa in a heard type pressure vessel at ETH Zurich using the pulse transmission technique on 26 mm diameter cores. The white Mugla marble was isotropic and displayed Vp of 6.86 km/s and Vs of 4.34 km/s at 300 MPa confining pressure. The Aubergine marble from Mugl...

SELECTION OF AN APPROPRIATE LOCATION IN ORDER TO ESTABLISH THE CONCENTRATOR NEXT TO ONE MINERAL DEPOSIT USING IDRISI SOFTWARE

(SGEM Scientific GeoConference, 2010, A. Aryafar, M. Chamani, M. Massinaei)

Show more

Geographic Information Systems (GISs) are very useful tools for managing, checking, and organizing spatial information from many sources and of many types in thematic layers. One of the most important applications of geographical information system (GIS) is the site selection for various problems. The main purpose of this research is the selection of the best place for establishes the processing plant next to the one mineral deposit, which is located in Howe Hill in United Kingdom (UK), using of IDRISI software. T...

SEM-EDX IDENTIFICATION OF PARTICLES FROM FOG IN AN INDUSTRIALLY POLLUTED REGION OF CZECH REPUBLIC

(SGEM Scientific GeoConference, 2010, V. Stoyanova, A. Shoumkova, J. Fisak, TS. Tsacheva)

Show more

The properties of individual particles, rather than bulk aerosol characteristics, determine the environmental and health impact of the atmospheric pollutants. Single particles have been sampled during 30 fog episodes at the mount Milesovka (837 m a.s.l.) located in the industrially polluted area of north Bohemian brown coalfield. More than 2000 of these solid, water insoluble particles, collected from May 2006 till July 2007, have been analyzed by SEM-EDX and classified according to their shape, size and elemental...
