OUR LOCATIONS ▾ ENGLISH ▾ About Markets Materials Innovation Sustainability Shareholder Careers Contact Metallurgy The metallurgy industry demands materials that deliver consistent results in extreme conditions. Our range of minerals and technical expertise combine to provide solutions for customers across four sectors: foundry, steel, refractories & welding. Foundry To avoid variations and scrapped castings, it’s important to use the right type and quality of sand for core and mould making. The right choice of sand should be determined by parameters such as a casting’s size, casting temperature, the type of metal in the casting and the production equipment used. The broad range of materials in our foundry portfolio enables us to meet customers’ precise requirements, from chemical composition to grain size distribution. Products include: Silica sands Olivine sands Mineral composites: FINMIX® Bentonite Vermiculite Chromite Steel, Refractory & Welding High temperature environments demand materials with exceptional refractory properties. Our portfolio of materials for steel, refractory & welding includes: Olivine sands (metallurgical and refractory grades) Refractory masses Silica sands Bauxite Manganese Wollastonite Rutile Silicates Iron based minerals Clays Feldspars Petalite How can we help you?

OUR LOCATIONS ▾ ENGLISH ▾ About Markets Materials Innovation Sustainability Shareholder Careers Contact Bentonite Bentonite contains a hydrated aluminium silicate clay mineral responsible for its sealing and lubrication properties. Natural bentonite is classified by the predominant balancing cation, normally sodium or calcium. All applications of bentonite rely on its reaction with water. Sibelco’s sodium bentonite bonding properties occur in the early stage of water absorption approximating its plastic limit of 50% to 70%. When mixed at low concentration in water, our sodium bentonite exhibits a stable thinning behavior. Bentonite is used in agriculture, building and construction, civil engineering, drilling and foundry.
