Embodiment 1
[0030] A method for producing soluble potassium from potassium feldspar, the process steps are:
[0031] (1) After the potassium feldspar is crushed to a particle size of 200 μm, it is mixed with an activator at room temperature for 7 minutes to obtain material A;
[0032] (2) After material A was soaked in an acid solution with a concentration of 60% for 5 minutes, material B was obtained, which was transferred to an ultrasonic microwave reactor, and the ultrasonic microwave reaction was carried out for 3 times under the condition of controlling the temperature of the material at 70°C. obtain intermediate products;
[0033] (3) After solid-liquid separation of the intermediate product, solid A and liquid A are obtained, and solid A is washed 3 times with water to obtain liquid B, which is mixed with liquid A uniformly to obtain liquid C. It is dried until the moisture content is 0.05%, and the soluble potassium product is obtained.

Embodiment 2
[0042] A kind of method that potassium feldspar produces soluble potassium, it is characterized in that, described processing step is:
[0043] (1) After crushing potassium feldspar to a particle size of 90 μm, mix it with an activator for 4 minutes at room temperature to obtain material A;
[0044] (2) After material A was soaked in an acid solution with a concentration of 90% for 4 minutes, material B was obtained, which was transferred to an ultrasonic microwave reactor, and the ultrasonic microwave reaction was carried out for 3 times under the condition of controlling the temperature of the material at 115° C., obtain intermediate products;
[0045] (3) After solid-liquid separation of the intermediate product, solid A and liquid A are obtained, and solid A is washed 2-5 times with water to obtain liquid B, which is mixed with liquid A uniformly to obtain liquid C. It is dried under the same conditions until the water content is 5%, and the soluble potassium product is o...
Embodiment 3
[0054] A kind of method that potassium feldspar produces soluble potassium, it is characterized in that, described processing step is:
[0055] (1) After the potassium feldspar is crushed to a particle size of 800 μm, it is mixed with an activator at room temperature for 9 minutes to obtain material A;
[0056] (2) After material A was soaked in an acid solution with a concentration of 80% for 4 minutes, material B was obtained, which was transferred to an ultrasonic microwave reactor, and the ultrasonic microwave reaction was carried out twice under the condition of controlling the material temperature at 150° C., obtain intermediate products;
[0057] (3) After solid-liquid separation of the intermediate product, solid A and liquid A are obtained, and solid A is washed 4 times with water to obtain liquid B, which is uniformly mixed with liquid A to obtain liquid C. It is dried until the moisture content is 0.08%, and the soluble potassium product is obtained.
