preparation example Construction
[0022] The preparation method of described a kind of water-soluble potassium salt comprises the steps:
[0023] In step 1, the inorganic base salt is uniformly mixed with the pulverized potassium-rich rock powder to obtain the first mixture; the first mixture is heated to no more than 300°C, and the inorganic base salt is melted to obtain the second mixture .
[0024] Preferably, the basic auxiliary agent and / or melting auxiliary agent can be mixed with the inorganic base salt, and then heated to no more than 300°C; wherein, the mass ratio of the inorganic base salt to the basic auxiliary agent is not less than 9 :1, the mass ratio of the inorganic base salt to the melting aid is 8:1 to 9:1; thereby ensuring that the mass ratio of the potassium-rich rock to the first mixture is 1:3 to 2:3.
[0025] Specifically, the inorganic base salt includes metal cations and acid radical anions, and the metal cations are selected from sodium, potassium, calcium, magnesium, lithium, iron, ...
