The industrial production process of magnesium carbonate is a complex and sophisticated process involving multiple steps and technologies.The following is a detailed analysis of the production process of magnesium carbonate industry:

Mineral processing and crushing:Select suitable magnesium ore for mineral processing,common magnesium ores include magnesite and dolomite.Grind and screen magnesium ore to obtain ore with suitable particle size.

Leaching reaction:Send the crushed ore into a leaching kettle,add a certain proportion of hydrochloric acid or sulfuric acid,and heat it to a certain temperature to dissolve the magnesium carbonate in the magnesium ore.Meanwhile,stir the leachate to accelerate the dissolution reaction.

Recrystallization:Purification of the solution by removing impurity ions from the leachate through filtration or precipitation.Subsequently,the purified solution is heated and evaporated to concentrate the magnesium carbonate solution.

Precipitation treatment:Add alkaline agents such as sodium carbonate(Na2CO3)to the concentrated magnesium carbonate solution to combine magnesium ions with carbonate ions to form magnesium carbonate precipitate.

Drying and packaging:Filter,wash,and dry the magnesium carbonate precipitate to obtain the finished magnesium carbonate product.According to different requirements,magnesium carbonate products can also undergo crushing,screening,and other treatments.

In summary,the industrial production process of magnesium carbonate includes multiple key steps such as beneficiation and crushing,leaching reaction,recrystallization,precipitation treatment,and drying and packaging.These steps together constitute the complete process flow for the production of magnesium carbonate.
