Process 1: Crushing and screening dolomite rock. The crushing and screening process is to obtain dolomite blocks. Dolomite blocks can be directly used as sand and gravel products in the construction industry, and can also be ground or calcined to obtain other products.
Sedimentary rock
Sedimentary rock - Limestones, Dolomites, Carbonates: Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO3). Dolomites are mainly produced by the …
