Example Embodiment
[0026] Example 1
[0027] In the Chaerhan Salt Field, the potassium content in the potash mine is 5.63% and the magnesium content is 7.22%. Adopting positive flotation process: the size range of crushed ore is 3~8mm, and the amount of fresh water added for cold decomposition is the content of magnesium chloride in the raw ore obtained according to the potash ore sampling test. Compared with the phase diagram of the quaternary water-salt system, it is calculated that just dissolved The theoretical value of the added amount of fresh water of magnesium chloride, then add fresh water to cold decomposition, magnesium chloride is dissolved in water, the solid phase is composed of potassium chloride and sodium chloride, and the flotation temperature is normal temperature. Introduce the ore slurry into the mineralization tank, add the saturated mother liquor of potassium chloride, sodium chloride, and magnesium chloride, and add the positive flotation agent and mix thoroughly. The positiv...
Example Embodiment
[0028] Example 2
[0029] Solid potash mine in Laos. The potassium content in the potash mine is 8.4% and the magnesium content is 5.13%. The positive flotation process is adopted. The crushed ore particle size ranges from 3 to 8mm. The addition of fresh water and cold decomposition fresh water is based on the potash mine sampling The content of magnesium chloride in the raw ore was obtained by the test, compared with the phase diagram of the quaternary water-salt system, the theoretical value of the amount of fresh water that just dissolved the magnesium chloride was calculated, and then fresh water was added to cold decomposition, the magnesium chloride was dissolved in the water, and the solid phase composition was potassium chloride and potassium chloride. Sodium chloride, the flotation temperature is normal temperature. Introduce the ore slurry into the mineralization tank, add the saturated mother liquor of potassium chloride, sodium chloride, and magnesium chloride, and add...

[0030] Example 3
[0031]Solid potash mine in Laos. The potassium content in the potash mine is 8.1%, and the magnesium content is 4.83%. The positive flotation process is adopted. The crushed ore size ranges from 3 to 8mm. The amount of fresh water added is based on the potash mine sampling The content of magnesium chloride in the raw ore was obtained by the test, compared with the phase diagram of the quaternary water-salt system, the theoretical value of the amount of fresh water that just dissolved the magnesium chloride was calculated, and then fresh water was added to cold decomposition, the magnesium chloride was dissolved in the water, and the solid phase composition was potassium chloride and potassium chloride. Sodium chloride, the flotation temperature is normal temperature. Introduce the ore slurry into the mineralization tank, add the saturated mother liquor of potassium chloride, sodium chloride, and magnesium chloride, and add the positive flotation agent and mix th...
