Application of the Taguchi orthogonal array design to Cr (VI) solvent extraction
Kul, M.; Cetinkaya, Ue. (SOC MINING METALLURGY EXPLORATION INC, 2010)In this study, the effects of various extraction and stripping parameters, such as equilibrium pH (7.0, 8.5 and 10), extractant concentration (5, 10 and 20 volume %), organic-to-aqueous (O/A) ratio and stripping agent type ... -
Effect of boronizing composition on boride layer of boronized GGG-60 ductile cast iron
Kul, M.; Oskay, K. O.; TemizkanA, A.; Karaca, B.; Kumruoglu, L. C.; Topcu, B. (PERGAMON-ELSEVIER SCIENCE LTD, 2016)Boronizing of GGG-60 nodular cast iron samples were performed by immersion in molten salts. These were based on borax containing eight reducing agents: Na2CO3, CaCl2, NaCl, NaOH, B4C, SiC, Al and ferrosilicon. Also the ... -
Rare earth double sulfates from pre-concentrated bastnasite
Kul, M.; Topkaya, Y.; Karakaya, I. (ELSEVIER SCIENCE BV, 2008)A mixture of rare earth double sulfates was produced from a Turkish bastnasite-containing pre-concentrate (low grade concentrate) by sulfuric acid baking, subsequent water leaching and precipitation with sodium sulfate. ...
