Beneficiation of quartz waste by flotation and by ultrasonic treatment
(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 ... -
A comparative study on the estimation of shear strength of rock masses using rock SSPC system and Hoek-Brown criterion
(2011)The shear strength of rock masses has vital importance for geotechnical projects such as slope stability, foundation and tunnels. The shear strength of the jointed rock mass can be estimated by different methods including ... -
Determination of grindability characteristics of zeolite
(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, ... -
Differential separation of albite from microcline by monovalent salts in HF medium
(Soc Mining Metallurgy Exploration Inc, 2003)Na-feldspar (albite) and K-feldspar (microcline or orthoclase) are major feldspar minerals with identical crystal structures and physico-chemical properties. Flotation appears to be a unique method of separating these ... -
Effect of H2O2 and nash addition to change the electrochemical potential in flotation of chalcopyrite and pyrite minerals
(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 ... -

(2015)Taşocağı açık işletmeciliği kazı, basamak oluşturma, delme-patlatma ve yükleme-taşıma yöntemiyle gerçekleştirilmektedir. Taşocağı işletmeciliğinin ilk adımını kazı, sonraki adımını ise kırma eleme oluşturmaktadır. Kırıcıya ... -
Evaluation of Turkish bentonite for removal of dyes from textile wastewaters
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2012)Removal of reactive dyes from textile industry wastewaters is a great economic and environmental challenge. In this study, systematic adsorption tests were carried out using natural and modified bentonites to remove a ... -
Madenciliğin yerel ekonomilere katkısı ve bazı sektörlerle karşılaştırmalı analizi: Balıkesir örneği
(2016)Madencilik, insanoğlunun ilk uğraş alanıdır. İnsanoğlunun kayaçları tanıması ve işlemesi, onun mineralleri ve madenleri de tanımasına ve işlemesine giden yolu da açmıştır. Madencilik sektörü, Türkiye'nin sanayileşmesi, ... -
Occurrence and properties of natron in the Miocene lacustrine Beypazari basin, Turkey
(E Schweızerbartsche Verlags, 2003)Natron, Na2CO3 . 10H(2)O, is a rarely forming evaporite mineral, which precipitates under the unique physicochemical conditions of Na wt.%, temperature and HCO3/CO3. Natron is observed in the upper parts of the lower trona ... -
Prediction of unconfined compressive strength of carbonate rocks using artificial neural networks
(Springer, 2013)The unconfined compressive strength (UCS) of intact rocks is an important geotechnical parameter for engineering applications. Determining UCS using standard laboratory tests is a difficult, expensive and time consuming ... -
Recovery of zinc from waste material using hydrometallurgical processes
(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
(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 ... -
Surface vs. bulk analyses of various feldspars and their significance to flotation
(Elsevier Science Bv, 2008)Cationic separation of Na-feldspar (albite) and K-feldspar (microcline) was earlier reported to be possible in the presence of monovalent salts. However, contrary to this result, the floatability of a series of K-feldspar ... -
Varying depositional environments of gypsum successions in the Upper Miocene Eskiehir-Sivrihisar lacustrine basin, NW Turkiye
(E Schweızerbartsche Verlags, 2003)The basement rocks of Eskisehir-Sivrihisar basin are made of Upper Paleozoic metamorphic rocks and Upper Cretaceous ophiolite complex. These rocks are overlain by Middle Miocene sedimentary rocks the base. Upper Miocene-Pliocene ... -
Zeta potential of teflon in presence of monovalent and divalent ions
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2019)In this study, the specific effects of Na+ and Ca2+ ions on natural hydrophobic Teflon particles and flat Teflon surfaces were investigated using zeta potential and contact angle measurements, respectively. The zeta potential ...
