Abstract (en)
[origin: WO2020169777A1] The invention relates to a process for producing solid particles made of an inorganic solid containing at least one alkali metal and/or alkaline earth metal, comprising at least the following steps: a) providing the inorganic solid containing at least one alkali metal and/or alkaline earth metal; b) extracting the at least one alkali metal and/or alkaline earth metal from the inorganic solid containing alkali metal and/or alkaline earth metal to obtain an extract containing the alkali metal and/or alkaline earth metal and a residue depleted in alkali metal and/or alkaline earth metal; c) separating the extract from the residue; d) working up the residue to obtain the solid particles, wherein at least one of the workup steps is selected from a group which comprises transporting, filling, packaging, washing, drying, pH-adjusting, separating by average particle size and/or mass and/or density, establishing an average particle size, magnetic separation, calcination, thermal rounding and surface coating.
