The lithium market has been expanding due to the high demand for lithium-ion batteries, which are essential electric and hybrid vehicles as well portable devices. This driven search new ore deposits development of more efficient extraction processing technologies. main methods used from hard rock ores include acid process, alkaline chlorination roasting. study investigated a process applied α-spodumene extracted in Brazil chloride (LiCl) production. underwent thermal treatment presence...
Thermodynamic stability of nanoparticles necessitates the use stabilizing agents to provide steric and electronic protection. Nevertheless, their activity selectivity remain suboptimal under moderate reaction conditions. In this study,...
Parameters affecting the kinetics of dissolution β-spodumene with hydrofluoric acid have been investigated. The experimental tests were carried out in a closed vessel. influence several parameters, such as stirring speed, temperature, and reaction time studied order to deduce reaction. other particle size −45 μm; HF concentration 4% v/v, solid–liquid ratio 0.95% w/v kept constant. results indicate that speed does not an important effect on mineral above 330 rpm. extent leaching increases...
This work describes the development of a new process for recovery Li, Al and Si along with proposal flow sheet precipitation those metals. The developed is comprised lepidolite acid digestion hydrofluoric acid, subsequent metals present in leach liquor. leaching operational parameters studied were: reaction time, temperature HF concentration. experimental results indicate that optimal conditions to achieve Li extraction higher than 90% solid-liquid ratio, 1.82% (w/v); temperature, 123 °C;...
Lithium (Li) is considered a strategic element whose use has significantly expanded. Its current high demand due to its in lithium ion batteries for portable electronic devices, manufacture and market are extensively growing every day. These days there great concern about the final disposal of these batteries. Therefore, possibility developing new methodologies recycle their components importance, both commercially environmentally. This paper presents results regarding important operational...
The progressive depletion of primary sources to obtain metals has led the search for alternative their recovery. In particular case titanium, titaniferous sands are a viable option obtaining this metal. This paper presents results dissolution titanium from Buenos Aires province (Argentina) in laboratory autoclave (450 mL capacity). operating parameters studied were as follows: different acids (HF, H2SO4 and mixtures these acids); leaching agent concentration, 5–20% v/v; temperature, 75–150...
Herein is presented the results of a study on hydrometallurgic extraction and recovery aluminum silicon by leaching kaolinitic clays with HF. The studied parameters were: temperature, reaction time, solid/liquid ratio, concentration, precipitating agent mass. In process, mineral dissolutions near 100% were obtained when working at 348 K, ratio 2% w/v, HF 12% v/v, for 120 minutes. leach liquor generated from dissolution contains H2SiF6and H3AlF6. Studies conducted to recover two valuable...
