Abstract

The invention discloses a strontium carbonate production method. The strontium carbonate production method comprises the following steps: S100: after smashing celestite and raw coal via a smashing machine, feeding the smashed celestite and raw coal into a bin; S200: feeding raw materials in the bin into a rotary kiln through an oscillating feeder (1) and a conveying device (2); S300, ball-millingrough strontium sulfide into powder through a ball-miller; S400: leaching to obtain leaching liquid containing strontium ions; S500: refining; S600: carrying out chemical combination to generate a strontium carbonate precipitate and sodium sulfide mixture; S700: washing, pulping, drying and smashing sodium carbonate obtained by filtering and separating to obtain strontium carbonate particles; andS800, cooling and packing to obtain a final strontium carbonate product. The quality of the strontium carbonate product is improved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a method for producing strontium carbonate. Background technique [0002] Strontium carbonate is an important inorganic chemical product, mainly used in fluorescent glass, electronic ceramics, magnetic ferrite industry and high-tech fields.
