The ore was crushed and ball milled to a particle size of 10–100 μm. The elemental compositions of raw materials and Si–Ca–K–Mg fertilizer were measured by XRF and the results are listed in Table 1. The K-feldspar ore is mainly composed of microcline (KAlSi 3 O 8), and little quartz (SiO 2) and albite (NaAlSi 3 O 8).

Potash is a group of minerals consisting of potassium salt mixed with the impure form of potassium carbonate (K 2 CO 3 ). The word potash was derived from the Dutch word "Potasch," which originally referred to wood ash. It cannot be produced synthetically. Until the 20 th century, potash was one of the most important industrial chemicals.
