Production and characterization of hydrophobic zinc borate by using palm oilNil Baran Acarali,Nurcan Tugrul,Emek Moroydor Derun,Sabriye PiskinDepartment of Chemical Engineering,Yildiz Technical University摘 要:Zinc borate(ZB)was synthesized using zinc oxide,......
resistance of 0.101 MΩ The bioleaching of natural pyrite is considered to be a bio-battery reaction,which distinguishes it from chemical oxidation reactions in ferric-ion and culture-medium(9k......
of nucleation and crystal growth(NG), interaction at phase boundaries(I), and diffusion(D) in order, and the pozzolanic reactions of slag and compound-activated red mud–coal gangue are mainly controlled......
, respectively. Compared with the reactions conducted without the addition of NaCl, those performed with the addition of an appropriate amount of NaCl finished at substantially lower temperatures. However......
efficiency and copper yield were systematically investigated in consideration of possible electrochemical/chemical reactions at 1200℃.The copper production yield reached 98.09% after 90 min......
℃ under galvanostatic conditions and explained in detail by the reactions and intermediate compounds formed in the borax. The effects of current density(100-800 mA·cm-2) and electrolysis time(10-40 min......
industrial applications of bioleaching, many regulatory enhancements and technological methods are used to accelerate the interfacial reactions. With advances in microbial genetic and sequencing technologies......
reactions were observed at different p H levels. At the higher p H level(p H > ~5), H2 CO3 reduction was the dominant cathodic reaction. The reaction was under activation control. At the lower pH......
="ChDivSummary">Carbonated decomposition of hydrogarnet is one of the vital reactions of the calcification–carbonation method, which is designed to dispose of low-grade bauxite and Bayer red mud and is a novel......
