Removal of Cadmium, Zinc, Lead and Copper by Sorption on Leaching Residue from Nickel Production
Odstránenie Cd, Zn, Pb a Cu sorpciou na vylúhovanom zvyšku z produkcie Ni A leaching resudue from the nickel production (LRNi), was used to study the removal of selected bivalent cations (Cd, Pb, Cu and Zn) from model aqueous solutions. Batch-type experiments have been performed in solutions with initial concentrations of heavy metals in the range of 20-400 mg.L and the adsorbent dosage 2 g.L. ...
متن کاملLeaching Recovery of Zinc, Cobalt and Manganese from Zinc Purification Residue
This paper reports on the recovery of zinc, cobalt and manganese by two-step leaching of zinc-plants purification residue with sulfuric acid. The residue, hot filter press cake (HFC), contains 14 % ZnO, 4.8 % Co3O4 and 22.9 % MnO. Effects of different parameters are determined and used to optimize the process. With acid to hot filter press cake (HFC) stoichiometry of 0.85, acid concentration of...
متن کاملUV/ H2O2 Advanced Oxidation Process for Simultaneous Removal of NO and SO2: A Review
This study presents a review on advanced oxidation processes (AOP) for simultaneous removal of NO and SO2. AOP is based on using a strong oxidant such as ozone and H2O2 which is able to generate highly reactive intermediates. The pollutant will be oxidized and removed by these intermediates. In recent years, AOP has been considered as an effective and attractive technology in the field of flue ...

در ایران بیمه خودرو سهم بزرگی در صنعت بیمه دارد. تعیین حق بیمه مناسب و عادلانه نیازمند طبقه بندی خریداران بیمه نامه براساس خطرات احتمالی آنها است. عوامل ریسکی فراوانی می تواند بر این قیمت گذاری تاثیر بگذارد. طبقه بندی و تعیین میزان تاثیر گذاری هر عامل ریسکی بر قیمت گذاری بیمه خودرو پیچیدگی خاصی دارد. در این پایان نامه سعی در ارائه راهی جدید برای طبقه بندی عوامل ریسکی با استفاده از اصول و روش ها...
UP-GRADATION OF MoO3 AND SEPARATION OF COPPER, IRON, ZINC FROM ROASTED MOLYBDENUM ORE BY A LEACHING PROCESS
The present research paper deals with the oxidation process of molybdenum ore. The main target of the present study is the up-gradation of MoO3 from roasted molybdenum ore by a leaching process without waste generation. The most important application of hydrometallurgical processing is the leaching process of the ore and it is the primary process to make pure metal from ore. The present investi...
