Problems solved by technology
The quality of the product produced by this method is good and stable, but the method mainly has the following problems: ① high energy consumption and large water consumption, which is a big problem in remote areas short of water and electricity; ② long production cycle, production small scale
Although this method greatly reduces energy consumption, labor intensity and production scale compared with the original method, the current production is not stable enough.
This is mainly because the properties of sodium nitrate-containing solutions are quite different from those of other inorganic salt solutions, and due to the uniqueness of resources and late mining, there are few basic thermodynamics, kinetics and "three-pass" data, which affects production design. and run without optimization
[0004] The existing extraction process of sodium nitrate ore adopts pool leaching, that is, put the sodium nitrate ore into the pool and soak it with water. , take evaporation or freezing extraction; From the perspective of operation, the existing pool leaching process cannot leach low-grade ore, and it cannot handle powder ore. consumption is too high

Description
technical field [0001] The invention relates to the technical field of mineral equipment, in particular to a dynamic dissolution extractor. Background technique [0002] From the 1960s to the 1990s, the production of sodium nitrate by using sodium saltpeter was generally small, and the production technology was quite primitive, basically using production routes such as mineral leaching, evaporation and concentration of leaching solution to desalinate, static crystallization and recrystallization refining. . At that time, the grade of sodium saltpeter ore mined was quite high, usually about 30%, and the proportion of water-insoluble matter was not large. Mineral leaching was usually soaked in a leaching tank, steam was directly heated and stirred, and three-stage countercurrent leaching was used. Such methods usually have a higher utilization rate of raw materials, and the concentration of the leaching solution is high, which is conducive to subsequent processing. After the...
