Abstract

La presente invención divulga un método para enriquecer litio, que incluye los siguientes pasos: S1, molienda en seco de minerales de litio para obtener polvos finos con un tamaño de grano no superior a 20 mm; y S2, fregado y clasificación de los polvos finos para obtener concentrados fregados. En el paso S2, el tamaño de grano de los concentrados depurados obtenidos por clasificación no es superior a 0,15 mm, y los minerales de litio incluyen minerales de arcilla de litio. El método para enriquecer litio de la presente invención puede realizar el enriquecimiento de minerales que contienen litio y la eliminación efectiva de minerales impuros, proporciona mejores materias primas para una sección posterior, reduce el consumo de energía y ahorra el coste de producción.The present invention discloses a method for enriching lithium, which includes the following steps: S1, dry grinding of lithium minerals to obtain fine powders with a grain size not exceeding 20 mm; and S2, scrubbing and classification of fine powders to obtain scrubbed concentrates. In step S2, the grain size of the purified concentrates obtained by classification is not more than 0.15 mm, and the lithium minerals include lithium clay minerals. The lithium enrichment method of the present invention can realize the enrichment of lithium-containing minerals and effective removal of impure minerals, provide better raw materials for further section, reduce energy consumption and save production cost.
