1, mining
The production of well salt began with the exploitation of salt mines. Salt ore is extracted from underground or groundwater by underground mining or solution mining.
2. Crushing and crushing
The mined salt ore usually needs to be crushed and broken for further processing and extraction.
3. Dissolution and extraction
Put the crushed salt ore into a dissolving tank or a brine tank, and add a proper amount of water to dissolve it. The dissolved brine will be pumped out for further extraction and treatment.
4, filtering and purifying
Through the process of filtration and purification, impurities and impurity particles in the brine are removed, making the brine more pure.
5. Crystallization and drying
The pure brine is crystallized to make the salt crystallize out gradually. The crystallized salt crystals will be separated and dried to remove excess water.
6, screening and grading
The dried salt crystals are screened and classified according to factors such as particle size and purity, so as to meet different market demands.
