Complementary minerals
Minerals alongside clinker and cement
Alongside clinker, cement and calcium carbonate, NAGTAR can structure urea, blast-furnace slag and a short list of industrial minerals. Each line has its own page. Availability still depends on the brief.
Clinker, cement and calcium carbonate stay the core lines. The products below are the adjacent options: urea and blast-furnace slag, industrial bulk minerals, and higher-value grades. Open the page that matches the brief. Specs and cargoes are confirmed per deal, not from this list.
Urea & blast-furnace slag
Two lines often raised next to a clinker or cement discussion. Urea is a fertilizer and industrial product. Blast-furnace slag is a cementitious addition. They are not substitutes for each other.
Industrial bulk minerals
Dolomite, lime, silica and pozzolan, moved as industrial bulk. A working range is 5,000 to 30,000 tonnes per cargo, depending on the product and the vessel. The parcel is confirmed cargo by cargo.
DolomiteRaw dolomite for steel, glass, agriculture and construction, in bulk cargoes.
LimeQuicklime or hydrated lime for steel, construction and environmental use.
SilicaIndustrial silica sand and lump for glass, construction and foundry, in bulk.
PozzolanNatural pozzolan for cement blending, shipped as industrial bulk.
Higher-value minerals
Grades where particle size, purity or calcination matter more than filling a hold. Calcium carbonate keeps its own page. Calcined dolomite, specialty silicas and industrial fillers are quoted against a technical brief, in bulk, big bags or containers.
Calcium CarbonateIndustrial CaCO₃ grades — purity, particle size and packing matched to your process.
Calcined DolomiteCalcined dolomite for steel, refractory and glass — distinct from raw dolomite.
Specialty SilicasTighter silica cuts and higher-purity grades for fillers, glass and industrial processes.
Industrial FillersMineral fillers matched to a process — or routed to CaCO₃ and specialty silica when that is the grade.
If the product is not listed
A name on this page is not a standing offer. If your brief is a different industrial mineral, send the product, the spec that matters, the volume and the destination. We will say whether an Algerian supply path looks realistic — including when the answer is no.
