Limestone (CaCO3) products are produced by crushing and screening naturally occurring limestone. Limestone consists primarily of carbonates of calcium and magnesium. Sibelco’s limestone products are available in a number of sizes ranging from aggregates to coarse ground and superfine grades.

Sibelco aglime is ground high quality limestone specifically graded to meet the needs of the agricultural industry. Stockfeed limestone and limestone grits are manufactured by milling the limestone to produce a range of products from less than 38µm to de-dusted limestone and limestone grits. Fine ground limestone also known as FGLS is manufactured by milling limestone down to a fine powder with the ability to control size distribution, purity, whiteness and surface area.
