Bacterial leaching of coal for the removal of pyritic S
Göktepe, Ferihan; Pooley, Frederick D. (2006)Most commonly used microorganisms are Thiobacillus Ferrooxidans and Thiobacillus Thiooxidans, which have been shown to be effective in the removal of pyritic sulphur from coal. This study presents the results of bacterial ... -
Beneficiation of quartz waste by flotation and by ultrasonic treatment
Göktepe, Ferihan; İpek, Halil; Göktepe, Mustafa (Oficyna Wydawnicza Politechniki Wroclawskiej, 2011)Quartz is one of the most important industrial minerals used in glass and ceramic industries and high quality quartz are preferred. Impurities from quartz are usually removed by magnetic separation or flotation. This study ... -
Characterisation and beneficiation studies for Balya lead-zinc mine wastes
Göktepe, Ferihan; Pooley, Frederick D.; Williams, K. P. (A A Balkema Publishers, 2000)The deposit of lead-zinc ore in Balikesir/Balya was mined and abandoned in the past. There is about 1 million tonnes of gravity and flotation tailings and slags containing considerable amount of lead and zinc, In this study ... -
Continuous ph and pulp potential measurements during complex sulfide ore flotation
Göktepe, Ferihan (2010)Control of pH is one of the most widely applied methods for the modulation of mineral flotation. There are many studies in the literature which show that flotation of chalcopyrite and pyrite with xanthate shows a strong ... -
Determination of grindability characteristics of zeolite
İpek, Halil; Göktepe, Ferihan (Oficyna Wydawnicza Politechniki Wroclawskiej, 2011)In this study grindability of zeolite was studied. The work index of zeolite was determined for three different test sieves. In terms of work indexes, there was insignificant difference between the test sieves. Additionally, ... -
Effect of H2O2 and nash addition to change the electrochemical potential in flotation of chalcopyrite and pyrite minerals
Göktepe, Ferihan (Taylor & Francis Ltd, 2011)The floatability of sulfide minerals can be affected by the redox conditions on particle surface and in the pulp and can be used as one of the parameters for the separation of sulfide minerals. In the present study, the ... -
Effect of pH on pulp potential and sulphide mineral flotation
Göktepe, Ferihan (2002)Control of pH is one of the most widely applied methods for the modulation of mineral flotation. In this study the effect of pH on potential in solution and sulphur minerals flotation is discussed with various electrodes. ... -

Göktepe, Ferihan (2002)Control of pH is one of the most widely applied methods for the modulation of mineral flotation. In this study the effect of pH on potential in solution and sulphur minerals flotation is discussed with various electrodes. ... -
An electrochemical investigation of sulphide ore flotation in the presence of Fe-2(SO4)(3)
Göktepe, Ferihan; Williams, K. P. (A A Balkema Publishers, 2000)Before measuring electrochemical potential of flotation pulp in the presence of Fe-2(SO4)(3), it has been measured in solution with five different electrodes for different concentration of Fe-2(SO4)(3). It show that potential ... -
Electrochemical potential in single and mixture of mineral slurries
Göktepe, Ferihan; Williams, K. P. (A A Balkema Publishers, 2000)Sulphides being electronic conductors, can act as a source or sink for electrons and hence can support electrode reactions at the surface. Electrochemical potential start to be a variation in flotation systems. As flotation ... -
Enrichment of pyrite from siirt- Madenköy copper plant tailings by flotation
Ceylan, Adnan; Bulut, Gülay; Göktepe, Ferihan (2012)Pyrite is present as a gangue mineral in most of complex sulphide ores and most of time it is removed as a tailing. However, beneficiation of pyrite from tailings could be important because of its economical value and for ... -
Recovery of zinc from waste material using hydrometallurgical processes
Kurama, Haldun; Göktepe, Ferihan (Amer Inst Chemical Engineers, 2003)A lead-zinc ore deposit in Balikesir/Balya, Turkey, was mined and abandoned almost 70 years ego. Nearly 1, 000, 000 tons of flotation tailings and 300, 000 tons of slag, which contain considerable amounts of zinc remain. ... -
Role of starch and metabisuphite on pure pyrite and pyritic copper ore flotation
Bulut, Gülay; Ceylan, Adnan; Soylu, Burhan; Göktepe, Ferihan (Oficyna Wydawnicza Politechniki Wroclawskiej, 2012)Depression of pyrite is very important in sulphide ore flotation. This paper investigates the role of non-toxic depressants on the flotation of pyrite. Starch and meta bisulphite were used as a depressant for pure pyrite ... -
Treatment of lead mine waste by a Mozley multi-gravity separator (MGS)
Göktepe, Ferihan (Academic Press Inc Elsevier Science, 2005)Increasing environmental awareness and pressure is focusing attention on metal removal leading to the accelerated development of contaminated land reclamation technologies. The majority of wastes associated with base metal ...
