Beschreibung
Zusammenfassung:	The invention relates to a potassium-containing rock comprehensive utilization technology, and concretely relates to a method for processing potassium-containing rock through industrial microwave. The technological method comprises: fully mixing potassium-containing rock, an auxiliary agent and an acid, reacting in industrial microwave equipment, performing solid-liquid separation after reaction, adding a neutralization agent into the liquid for neutralization reaction, performing separation, and performing concentration crystallization on the liquid to obtain a potassium fertilizer, adding sodium hydroxide into the solid to perform alkalization microwave reaction, so as to prepare sodium metaaluminate. The method is short in reaction time and low in energy consumption, a generated fluorine-containing gas is adsorbed for obtaining white carbon black and an auxiliary agent, the recovery rate of a potassium-dissolving auxiliary agent reaches 98% or more, and the method has good technological prospect.
