In order to reduce CO2 emission, the sequestration using particulate steelmaking slag in water is world widely being studied through a Ca-carbonation method. As consequence, improved efficiency of Ca leaching from steelmaking-slag particles contributes significantly increasing amount fixed CO2. Therefore, this study, for purpose understanding particles, rate week acidic solution was analyzed by...

This study investigates vanadium extraction from steel converter slag the LD (Linz-Donawitz) process. has been used as an active bed material in a biomass boiler combustion technique called oxygen carrier aided (OCAC). usage could be compared to roasting step common roasting-leaching method for extraction. Leaching of prior use is undesirable materials OCAC are removed. successfully leached fol...

In this study, potassium ferrocyanide, a nontoxic cyanide precursor in dark and diffuse reflection environment, was applied as reagent for the leaching of gold. The free ions could gradually release from ferrocyanide solution under ultraviolet light. Orthogonal experiments were performed gold ore to analyze effect pH, dosage, temperature system UV Response surface methodology (RSM) explore role...

One concern for recycle and reuse of scrap tires is the leaching of tire constituents (organic and inorganic) with time, and their subsequent potential harmful impacts in environment. The main objective of this study was to examine the leaching of dissolved organic carbon (DOC), dissolved nitrogen (DN), and selected inorganic constituents from scrap tires. Different sizes of tire chips and crum...

Recent works suggest that the use of ionic liquids in copper solvent extraction industry is feasible. However, reports did not real solutions (or synthetic with various elements). This fact remains poorly established, and interaction efficiencies are still under study. The objective this research to explore stripping four major elements present a industrial pregnant leach solution (Cu(II), Fe(I...
