Low-temperature lithium extraction from α-spodumene with NH4HF2: Modeling and optimization by least squares and artificial neural networks

Autor: Mario Humberto Rodriguez, Alexander C. Resentera, Marcelo R. Esquivel

Publikováno v: Chemical Engineering Research and Design. 167:73-83

In this research, an efficient method of lithium extraction from α-spodumene by thermal treatment with NH4HF2 was optimized. Temperature (T), α-spodumene:NH4HF2 molar ratio (m), and reaction time (t) were studied using a two-level univariate strate
