In its natural state, calcium carbonate occurs as chalk, limestone and marble. Mississippi Lime ground calcium carbonate is mined from one of the purest limestone deposits in the world with an average purity of 98.5% CaCO 3.. Both wet and dry grinding methods are commonly used in processing the limestone for industrial uses.
Calcium carbonate, the chief component of limestone, is a widely used amendment to neutralize soil acidity and to supply calcium (Ca) for plant nutrition. The term "lime" can refer to several products, but for agricultural use it generally refers to ground limestone. Production
Calcium carbonate grains also disintegrated into smaller nanoparticles. Thus, the protein/CaCO 3 /chitin nanofiber complex was successfully obtained from crab shells by HPWJ mechanical treatments. To further characterize the morphology of the nanofiber, calcium carbonate was removed from samples treated with 0, 1, and 5 passes.
