Abstract: An apparatus for thermally treating lithium ores and other mineral raw material may include a comminution apparatus, a pelletization apparatus, and a thermal treatment apparatus. The pelletization apparatus can be a mechanical fluidized bed reactor. Further, a process for thermally treating lithium ore and other mineral raw material may involve comminuting the mineral raw material in a comminution apparatus to form a first product, pelletizing the first product in a mechanical fluidized bed reactor to form a second product, and thermally treating the second product in a thermal treatment apparatus. Ninety percent of all particles in the second product may have a particle size between 50 ?m and 500 ?m.

Abstract: A method may be employed to produce a fertilizer granulate comprising an ammonium salt and, as a filler material, limestone, dolomite, and/or magnesite. At least a proportion of the limestone or dolomite or magnesite is at least partially calcinated prior to use in the fertilizer granulate. A targeted adjustment of the reactivity of the filler material may occur by its degree of calcination and/or its calcite proportion. If, for example, dolomite is used as a filler material, the calcination results in separation of carbon dioxide from the mineral. This calcination is a two-stage process in which the dolomite is first converted to periclase (MgO) and calcite (CaCO3), and the calcite is also converted by decomposition and release of carbon dioxide only at a higher temperature.
