Example Embodiment
[0022] Example 1
[0023] The method for producing sodium nitrate from sodium saltpeter ore, the refinement process steps are
[0024] 1. Ore crushing: the sodium saltpeter ore is crushed with a jaw crusher, and the particles with a particle size ≤ 2cm are screened and loaded into the leaching tank.
[0025] 2. Five-stage countercurrent circulation leaching: the washing mother liquor enters the five-stage countercurrent circulation leaching, the first stage is the fifth leaching of ore, the second stage is the fourth leaching of ore, and so on, the temperature of the leaching liquid is gradually As it rises, the concentration of the washing liquid also increases step by step, and the leaching liquid is obtained. The leaching time of each stage is 10h.
[0026] 3. Three-stage washing: Wash the ore after five-stage leaching with 0.5 times the weight of the ore. The washing sequence is the first stage, the second stage, and the third stage. The first stage is the third washing of the...
Example Embodiment
[0039] Example 2
[0040] This embodiment has the same process steps as the embodiment 1, and only differs in some process parameters, which are specifically as follows:
[0041] 1. Ore crushing: crush the ore to particles with a particle size of ≤ 2cm, and load it into the leaching tank.
[0042] 2. Five-stage countercurrent circulation leaching: the washing mother liquor enters the five-stage countercurrent circulation leaching, the first stage is the fifth leaching of ore, the second stage is the fourth leaching of ore, and so on, the leaching temperature is at room temperature~ The concentration of washing liquid is also increased step by step at 50°C, and the leaching liquid is obtained. The leaching time of each stage is 8h.
[0043] 3. Three-stage washing: Washing step by step with 0.5 times the weight of the ore. The order of washing is the first, second and third. The first stage is the third washing of the ore, the second stage is the second washing of the ore, and the th...
