PYROMETALLURGICAL METHOD FOR OBTAINING COMPOUNDS OF LITHIUM AND INTERMEDIATES FROM ALPHA-SPODUMENE AND LEPIDOLITE

摘要

Pyrometallurgic process for obtaining lithium compounds and intermediates, the process being characterized by comprising the steps of a) contacting lithium aluminosilicate particles with at least a fluorine solid compound, b) heating until a temperature of 25 to 900° C. obtaining a solid mixture and c) carrying out at least a leaching process of the mixture in step b).
