In the extraction process of (type B) gelatin from animal hides and bones, lime maintains the required high pH levels.
Limestone and dolomite are ingredients in calcium ammonium nitrate-based fertilizers.
Lime reacts with carbon at high temperatures to produce calcium carbide (CaC2). This is used as a raw material to produce fertilizers or acetylene. It is also part of the refining processes in steel making.
Calcium phosphates are produced as a result of the reaction of lime or limestone with phosphoric acid. These are part of foodstuffs, toothpastes, pharmaceuticals and fertilizers.
Hydrated lime is used for fruit conservation; to capture CO2 during fruit ripening in conservation fridges.
