Celestite production is not aimed at obtaining high grade concentrates. Most of the world's resources celestite States has been the primary product (ore or concentrate) and production of soluble strontium containing compound (SrCo 3 strontium salt, etc.) as one. This determines the production of lapis lazuli and its strontium salt, including the two parts of mineral processing and strontium salt production and processing technology.
   Re-election is the most common method used in lapis lazuli dressing. The most common structural process is the process of jigging - shaker. Jigging is used to process coarse materials and shakers are used to process fine grade materials. This process structure is adopted in the celestite re-election of the Xiangyang Aijingshan antimony ore plant in Jiangsu, China.
