CALCINOR SERVICIOS

Calcinor (formally CALCINOR SERVICIOS) is a Spanish industrial minerals company dedicated to the preparation of industrial minerals used as chemical reagents. According to its official website, the company describes itself as a family company with an industrial culture and a commitment to continuity in the industrial minerals sector. Its core activity is the calcination and processing of limestone and dolomite into lime, dolomite and related mineral products, which are supplied as chemical reagents and functional raw materials to a wide range of downstream industries. The company positions itself as a leader in its zones of influence, both in calcined products and especially in differentiated products such as dolomite refractories, PCC (precipitated calcium carbonate) and talc. Calcinor states that it is active on five continents, exporting its products and operating a network of companies set up around Europe and Africa. Its application sectors span industry, construction, environment and agri-food, with specific end-uses in the iron and steel industry, metallurgy, the paper industry, glass and ceramics, the chemical industry, paint, adhesives and sealants, rubbers, the mining industry, plastics, soil stabilisation, civil works, water treatment, sludge treatment, gas treatment, agriculture, livestock farming, animal feed, the sugar industry and human food. Calcinor markets a portfolio of branded product lines. CALINTEC® is a micronized calcium oxide with very low particle size and improved dispersion, with a controlled particle size distribution centred in the 40 micron range (CALINTEC 40 has a d50 below 40 µm, around 7 µm), designed for polymers and rubbers, animal feed and agriculture/livestock applications. STABYCAL® is a range of products developed through collaborations and R&D to optimise the stabilisation of clay soils with lime, including STABYCAL and STABYCAL SP, targeting civil works and soil stabilisation as well as agriculture. REFRADOL® is a sintered dolomite with high resistance to hydration, produced through an industrial process Calcinor describes as unique in the world, used as a raw material for refractories in the iron and steel industry and metallurgy. The company operates a network of production plants and subsidiaries. Plant names referenced in its product documentation include CALMIT LLIERCA, CALERA DE ALZO, ANDALUZA DE CALES, CAL DE CASTILLA, CALES DE LA PLANA, DOLOMITAS DEL NORTE, LAFARGE CALCINOR MAROC and EUROCHO. Calcinor also emphasises sustainability, stating that it helps protect the environment by optimising and using only strictly necessary resources through the development of new technologies and industrial processes. Its news feed references sustainability reporting by group companies such as Kelsen and the rebranding of Cales de Llierca as Calmit Llierca. As a family-owned private company, Calcinor does not appear to be listed on a stock exchange. Its formal registered name in public data sources is CALCINOR SERVICIOS, described simply as a Spanish company. The group combines an industrial-minerals extraction and processing base with branded specialty product lines and technical advisory services for customers.

Calcinor is a Spanish industrial minerals company whose formal registered name in public data sources is CALCINOR SERVICIOS, described as a Spanish company. The group presents itself as a family company with an industrial culture and a commitment to continuity in the industrial minerals sector, indicating a long-term, family-owned corporate structure rather than a listed public company. The company's business is built on the preparation of industrial minerals used as chemical reagents. Its core industrial activity is the calcination and processing of limestone and dolomite into lime, dolomite and related mineral products. Over time, Calcinor has developed differentiated, branded product lines that go beyond commodity lime. According to its official website, it is a leader in its zones of influence both in calcined products and especially in differentiated products such as dolomite refractories, PCC (precipitated calcium carbonate) and talc. Calcinor has expanded geographically and industrially through a network of companies and production plants around Europe and Africa, and it states that it is active on the five continents through exports. Plant names referenced in its product documentation include CALMIT LLIERCA, CALERA DE ALZO, ANDALUZA DE CALES, CAL DE CASTILLA, CALES DE LA PLANA, DOLOMITAS DEL NORTE, LAFARGE CALCINOR MAROC and EUROCHO. The presence of a joint entity named LAFARGE CALCINOR MAROC indicates a partnership or joint venture in Morocco, extending the group's footprint into North Africa. Product development has been a central theme. CALINTEC® is a micronized calcium oxide with very low particle size and improved dispersion, with a controlled particle size distribution centred in the 40 micron range; CALINTEC 40 has a d50 below 40 µm, around 7 µm. It is used in polymers and rubbers as a drying and moisture-capturing agent, in animal feed as a chemical reagent for the saponification reaction in calcium soaps for ruminant feed, and in agriculture and livestock for its biocidal action. STABYCAL® was developed through collaborations and R&D activities to optimise the stabilisation of clay soils with lime; the range selects and modifies calcium oxides and hydroxides to strengthen performance and reactivity and reduce product loss during application, and includes STABYCAL and STABYCAL SP, the latter reducing dust generation and recommended for agriculture and civil works close to inhabited or sensitive sites such as airports, tunnels and railways. REFRADOL® is a sintered dolomite with high resistance to hydration, produced through an industrial process Calcinor describes as unique in the world, used as a raw material for refractories in the iron and steel industry and metallurgy, including dolomite gunning plains for ladles and electric arc furnaces. Corporate identity has evolved within the group. A news item dated May 28, 2026 reports that Cales de Llierca renewed its corporate identity and would operate as Calmit Llierca. Another news item dated September 25, 2026 covers Kelsen presenting its 2025 Sustainability Report, reinforcing its commitment to continuous improvement. These items illustrate the group's emphasis on sustainability and on aligning subsidiary brands under a coherent identity. Calcinor describes itself as committed to sustainable growth, helping to protect the environment by optimising and using only strictly necessary resources through the development of new technologies and industrial processes. Its application sectors span industry, construction, environment and agri-food, with end-uses in the iron and steel industry, metallurgy, paper, glass and ceramics, chemicals, paint, adhesives and sealants, rubbers, mining, plastics, soil stabilisation, civil works, water treatment, sludge treatment, gas treatment, agriculture, livestock farming, animal feed, the sugar industry and human food. The company also offers expert technical service to advise customers on the individual characteristics of each process.
