All minerals

Thirteen minerals, each with its grade ladder, typical analysis and the industries that buy it.

Talc

Soft, platy magnesium silicate. The workhorse extender in paint, plastics, paper and rubber.

Clays

China Clay (Kaolin)

Fine white aluminium silicate. Brightness and coverage in paper, paint and ceramics.

Ball Clay

Highly plastic sedimentary clay. Green strength and workability in ceramic bodies.

Bentonite

Swelling montmorillonite clay. Binding, sealing and viscosity in foundry and drilling.

Mica

Mica Powder

Wet- and dry-ground muscovite. Crack resistance, barrier and sheen in coatings.

Mica Flakes

Graded muscovite flake. Insulation, drilling loss control and decorative effect.

Wollastonite

Acicular calcium metasilicate. Reinforcement without asbestos, in plastics and ceramics.

Feldspar

Potash and soda grades. The flux in glass, sanitaryware and ceramic bodies.

Carbonates

Dolomite

Calcium magnesium carbonate. Flux, filler and magnesia source for glass and steel.

Calcite / Ground Calcium Carbonate

High-brightness GCC. The cheapest way to add volume without losing whiteness.

Silica

Silica Sand

Washed and graded quartz sand. Glass, foundry moulding and filtration.

Quartz Powder

Micronised high-purity quartz. Hardness and chemical resistance in engineered surfaces.

Others

Barytes (Barite)

High specific gravity barium sulphate. Drilling mud weighting and sound-deadening fillers.

Not listed?

India exports a long list of industrial minerals beyond this range — graphite, bauxite, chromite, gypsum, attapulgite, garnet, vermiculite and others. If you buy something we do not show, send the specification and the annual tonnage and we will tell you honestly whether we can source it well or not at all.
