Kinetic analysis of total Lead from spent Car battery by hydrochloric acid leaching
A study of the kinetic analysis of total lead from spent Car battery ash by hydrochloric acidleaching has been examined. The physico-chemical analysis of the ash powder was carried outby the Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and X–ray diffraction (XRD).The effects of the acid concentration, temperature and particle size on the rate of battery ashdissolution have been investi...
متن کاملLeaching of basic oxygen furnace sludge with sulphuric acid
In this study the hydrometallurgical processing of BOF sludge in the sulphuric acid solutions under atmospheric pressure and temperatures up to 100 °C is investigated on a laboratory scale. The influence of sulphuric acid concentration, temperature, time and liquid to solid ratio (L:S) on the leaching process was studied. The main aim of this study was to determine optimal conditions when the m...
متن کاملStudies on Platinum Recovery from Solutions after Leaching of Spent Catalysts by Solvent Extraction
The results of studies on the separation of platinum(IV) ions by solvent extraction from aqueous solutions after leaching of spent catalysts have been reviewed. The following processes have been discussed: acid leaching of spent catalysts and solvent extraction of platinum(IV) ions by using organophosphorous acids, amines and oximes as the extractants. In hydrometallurgical leaching of spent au...

متن کاملThe Influence of Mechanical Activation of Chalcopyrite on the Selective Leaching of Copper by Sulphuric Acid
Base metal sulphides are an important source of various metals. They are typically intergrowth and due to the complex nature of their ores, the hydrometallurgical technique is the very convenient way of extracting the desired component. If it is possible to extract the metal from an ore selectively, the subsequent processing steps become less complicated. Mechanical activation seems to be a fav...
