Abstract
Process for obtaining lithium compounds and intermediate compounds, comprising the following steps: a) contacting aluminosilicate particles, for example α-spodumene, with at least one fluorine compound, for example HF, NaF or others; b) stirring the mixture increasing the temperature until reaching an appropriate temperature; c) carrying out at least a precipitation and filtration process of the mixture of step b), and, d) recovering the lithium compound. The process may comprise using HF at a concentration between 5 and 30% v/v or NaF at a concentration between 5 and 30% w/v; a solid/liquid ratio of step a) between 0.9 and 14.4% w/v; a particle size of between 29 and 200 μm. The final lithium product of the process may be lithium carbonate or lithium fluoride.
