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 کاملRecovery of Copper from Copper Slag and Copper Slag Flotation Tailings by Oxidative Leaching
Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...
متن کاملLeaching of Lead and Zinc from a Low-Grade Oxide Ore in Citric Acid Media
Leaching of a low-grade lead and zinc oxide ore was studied by an organic reagent, citric acid. The quadratic mathematical models were developed for the relationship among the influential parameters and lead and zinc recoveries. Leaching rate was strongly affected by the interactive effects of factors. It was also found that the quadratic effects of stirring speed and linear<e...
متن کاملLeaching of Metals from Metallurgical Wastes in pH-static System: an Experimental Approach
The leaching characteristics of slag and fly ash from copper-cobalt smelting in the Zambian Copperbelt were studied using pH-static leaching experiments (CEN/TS 14997). The release of metallic contaminants as a function of pH and the influence of fine dust particles and/or time on leaching were investigated. Three types of slag samples with decreasing portion of particles < 500 μm were prepared...
