A method for strontium-rich table salt preparation and strontium content regulating and controlling is disclosed. The method includes (1) subjecting strontium-containing brine to at least two steps ofconcentration crystallization, with a part of water being evaporated and gypsum liquid and salt crystals being generated in each step of concentration crystallization; (2) discharging a part of the gypsum liquid generated in each step of concentration crystallization and filtering residual concentration crystallization liquid to obtain salt crystals and concentrated brine; and (3) drying the saltcrystals obtained in each step to obtain at least two types of strontium-containing table salt products having different strontium contents. The products include at least one strontium-rich table salt product. Through the method, the strontium in the brine is effectively enriched into the table salt products, and the strontium content of the table salt product can be effectively regulated and controlled, and therefore, the strontium-containing table salt products including strontium-rich table salt and having different strontium contents can be prepared according to practical needs.
