Industrial Minerals

Process minerals for industry

Non-metallic materials for drilling, ceramics, construction, glass, refractory supply, chemicals and industrial fillers.

Barite / Baryte

Drilling and industrial barite

Barite is supplied for drilling fluid weighting, industrial fillers, paint, rubber and chemical buyers. Drilling-grade lots should be checked against API requirements, especially specific gravity and soluble salts.

Purity: 92% - 98% BaSO4
API: SG 4.20+ available
Buyer check: SG, BaSO4, moisture, mesh size and soluble alkaline earths

Fluorite / Fluorspar

CaF2 feed for metallurgical and ceramic use

Fluorspar is used as a flux in steelmaking, in ceramic bodies and glazes, and as feedstock for chemical applications. Lot value depends strongly on CaF2 content and silica or carbonate impurities.

CaF2: 50% - 90%+
Forms: lumps, crushed material and powder by buyer requirement
Buyer check: CaF2, SiO2, CaCO3, moisture and sizing

Gypsum

Construction, cement and plaster grade gypsum

Gypsum is supplied for cement retarders, plaster, boards, agriculture and construction users. Buyers normally require consistent whiteness, controlled moisture and reliable sizing for grinding or calcination.

Purity: 90% - 95% typical
Forms: lumps, crushed and screened material
Buyer check: CaSO4.2H2O, moisture, insolubles, whiteness and size

Magnesite

Raw and calcined magnesite supply

Magnesite is supplied for refractory, agricultural, chemical and magnesium compound applications. Raw ore is evaluated by MgO content, while calcined material is evaluated by burn quality and reactive MgO.

Raw MgO: 42% - 47%
Calcined MgO: 85% - 90% depending on processing
Buyer check: MgO, CaO, SiO2, Fe2O3, LOI and sizing

Phosphate Rock

Phosphate feedstock for fertilizer and chemicals

Phosphate rock is supplied for fertilizer, phosphoric acid, animal-feed mineral and industrial chemical users. Commercial suitability is confirmed by P2O5 content, carbonate level, silica, moisture and size distribution.

Grade: P2O5 assay based by lot
Forms: lumps, crushed material and screened feed
Buyer check: P2O5, CaO, SiO2, MgO, CO2, moisture and sizing

Bauxite

Alumina-bearing ore for refractory and industrial buyers

Bauxite lots are evaluated by alumina content, silica, iron and calcination behavior. Material can be positioned for refractory, alumina, cement and industrial mineral buyers depending on assay.

Al2O3: 45% - 62%
Forms: raw and calcined options by lot
Buyer check: Al2O3, SiO2, Fe2O3, TiO2, LOI and size
