Industry
Foundry & Metallurgy
Foundries and metal plants specify performance: green strength for bentonite, size for silica, purity for silicon metal and alumina. Each is its own qualification path.
AI-generated illustration of this industry.
How this industry consumes minerals
Moulding lines and melt shops run on repeatable inputs. A clay or metal that passes one heat but drifts next month is a scrap risk. Trials and then cadence.
US market focus
US foundries and metallurgical buyers need materials that clear plant trials and then arrive monthly. Higher-barrier lines (silicon metal, specialty alumina) often lean earlier on multi-country partners.
How we approach US buying
Immediate: foundry bentonite and industrial silica where performance is demonstrable. Selective: silicon metal and specialty alumina after feasibility — not as spot catalogue claims.
Buyer segments
Foundries and casting plants
Green strength and sand trials before programme.
Steel and aluminium-related buyers
Flux and metal chemistry windows.
Refractory and metallurgical distributors
Specialty grades into qualified accounts.
Path to a first programme
01.Name the use
Foundry clay, silica, metal or refractory alumina.
02.Plant trial
Performance or chemistry validation.
03.Feasibility on origin
Especially for silicon metal and specialty alumina.
04.Programme
Recurring supply with disclosed backup origins.
How each product fits
- Activated / API Bentonite
Foundry grade — not the drilling viscosifier brief.
- Industrial Silica
Foundry sand size and impurity windows.
- Silicon Metal
Selective — chemistry and multi-country partners often early.
- Specialty Alumina
Specialty refractory/ceramic — long qualification.
- Dolomite
Raw flux stone where specified.
- Calcined Dolomite
Calcined product for steel/refractory — not raw stone.
Questions a US desk usually asks
- Foundry bentonite or drilling bentonite?
- Is silicon metal or specialty alumina a feasibility brief or a ready RFQ?
- What monthly cadence must the melt shop hold?
Supply continuity
Algeria is primary where the line exists. Silicon metal and specialty alumina may rely earlier on multi-country partners — always disclosed in the commercial frame.

Notes tied to the minerals in this industry — for buyers who want context before they send a brief.
API barite for US oilfield buyers: density, cadence and continuity
How US mud houses and Gulf Coast distributors brief API-oriented barite — density checks, trial parcels, Algeria-first supply with multi-country backup. No price list.
Drilling vs foundry bentonite: two offers, not one clay
Why NAGTAR separates drilling and foundry bentonite briefs — API-style viscosifier tests versus green strength — and how US buyers should inquire.
Filter-grade diatomite: what buyers test before they buy
Natural diatomite is not a filter aid until processing and plant trials clear permeability and retention. How US filtration desks should brief NAGTAR.
Silica sand for glass: size, iron and why flour is a different buy
Silica sand for glass: what buyers should specify on size, SiO2 and Fe2O3, and why foundry sand, construction sand and flour are different orders.
What dolomite is used for in steel, glass and agriculture
Dolomite uses in steel, glass and agriculture, and why raw dolomite for steel is a different purchase from calcined dolomite. Fraction and CaO/MgO are confirmed on the lot.
Calcined dolomite or raw dolomite: dolomie calcinée is not the stone
Why calcined dolomite, or dolime, is the stone after CO2 is driven off, and why dead burned dolomite is a lot check rather than a catalogue grade.
