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 ... -
Treatment of lead mine waste by a Mozley multi-gravity separator (MGS)
(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 ... -
Effects of bivalent salts on the flotation separation of Na-feldspar from K-feldspar
(Pergamon-Elsevier Science Ltd, 2003)Despite similarities in the physical and physico-chemical properties of Na- and K-feldspars, their flotation separation with monovalent ions exhibited a reasonable success. Further studies have been therefore initiated to ... -
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 ... -
Selective separation of sodium and potassium feldspar minerals from orebodies
(Trans Tech Publications Ltd, 2004)Feldspar minerals are major commodities used in the production of glass and ceramics. A major proportion of feldspar rocks such as granites, pegmatites and nepheline syenites embody both Na-feldspar (Albite) and K-feldspar ... -
Application of Support Vector Machines and Relevance Vector Machines in Predicting Uniaxial Compressive Strength of Volcanic Rocks
(Pergamon-Elsevier Science Ltd, 2014)The uniaxial compressive strength (UCS) of intact rocks is an important and pertinent property for characterizing a rock mass. It is known that standard UCS tests are destructive, expensive and time-consuming task, which ... -
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, ... -
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 ... -
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 ... -
