India's industrial mineral production is geographically concentrated in a few key states, each with distinct mineral specialisations. Rajasthan is India's mineral heartland, accounting for the largest share of industrial mineral output. The state produces talc (Udaipur, Bhilwara), calcite and calcium carbonate (Udaipur, Rajsamand), feldspar (Ajmer, Bhilwara), dolomite (Nagaur), marble and stone, and wollastonite (Sirohi). The concentration of multiple minerals in a single sta

Industrial minerals are not commodities — they are specification products. The same mineral can range from a low-value agricultural grade to a high-value pharmaceutical grade depending on processing and purity. Particle size is the most critical specification for most applications. It is expressed in microns (µm) and characterised by D50 (median diameter), D97 (97% of particles below this size), and sometimes D90. Mesh size is an older unit still used in India: 300 mesh = app

Evaluating an industrial mineral supplier requires looking beyond the price per tonne. For B2B buyers, the following framework covers the most critical due diligence points. Mine ownership is the first question. A supplier who owns the mine has direct control over raw material quality, supply continuity, and pricing. Traders who aggregate from multiple small mines may offer price flexibility but carry supply consistency risks. For long-term supply relationships, mine ownershi

Qualifying a new feldspar supplier requires a systematic process. The following steps ensure you are dealing with a reliable partner capable of consistent quality and supply. First, verify mine ownership. Feldspar processors who own their mines have better control over raw material variability. Ask for mine lease documentation and a quarry map showing the working faces. Second, inspect processing facilities. Visit the plant and assess: crushing and grinding equipment, classif

India is a significant feldspar exporter, with annual exports exceeding 500,000 tonnes. The primary export destinations are South Korea (for its large ceramics and electronics industries), Taiwan, Italy (for premium ceramic tile and sanitary ware), Turkey, and various Southeast Asian markets. Rajasthan is the dominant feldspar-producing state, with major deposits in Ajmer, Bhilwara, Jhunjhunu, and Pali districts. The material is processed in Rajasthan and typically transporte

Understanding which industries consume which minerals helps buyers identify alternative sources and substitutes, and helps suppliers target the right customers. The paints and coatings industry is one of India's largest consumers of industrial minerals. Calcium carbonate, talc, kaolin, and barite are all used as extender pigments — they replace expensive titanium dioxide while maintaining or enhancing film properties like opacity, sheen, and scrub resistance. India's paint ma
