| description | The invention discloses a method for preparing potassium chloride from low-grade potassium resource ore at low energy consumption, and relates to the technical field of inorganic salt. The method comprises following steps: 1, decomposing low-grade potassium resource ore; 2, evaporating potassium dissolved brine to prepare sylvine and carnallite; 3, preparing artificial sylvine; 4, preparing a sylvine solution; 5, diluting the sylvine solution; 6, building a solar pond; 7, horizontally filling the solar pond layer by layer; 8, running the solar pond; 9, hot melting sylvine; 10, filtering; 11, cooling and crystallizing; and 12, low-temperature mother liquor recycling. The method has the beneficial effects that the energy consumption is low, the cost is saved, utilization of low-grade potassium resources is improved, the solubility of potassium chloride is improved, and the energy consumption in the recycling process of the low-grade potassium resources is reduced.
