Cales de Llierca is the leading producer of coated and uncoated Precipitated Calcium Carbonate (PCC.) Precipitated Calcium Carbonate (PCC) is the most complex product of all the products we produce: it requires special controls and in-depth knowledge of the different parameters involved in the precipitation reaction and subsequent treatments. By modifying the above parameters, we accurately select […]


We offer an exclusive range of products for every application. Calcium hydroxide or slaked lime and the specific products derived from it, are obtained through the calcium oxide hydration process: CaO + H2O  →  Ca(OH)2 + Heat Hydration of quicklime generates heat, helping to dry and disinfect the materials being treated. Calcium hydroxide based products are used in […]


Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings. Calcium and magnesium oxide or calcined dolomite are obtained from dolomitic minerals such as calcium carbonate and magnesium (Ca Mg (CO3) 2, through the calcination process. Ca Mg (CO3)2 + Heat […]
