Kumar Minerals is a prominent mining company specializing in the extraction of high-quality quartz and quartzite lumps and blocks. Operating primarily in the mineral-rich states of Rajasthan and Andhra Pradesh, the company leverages vast deposits in these regions to produce premium-grade silica minerals. Rajasthan’s arid landscapes and Andhra Pradesh’s geologically favorable terrains provide ideal conditions for large-scale lump and block mining, ensuring consistent output of durable, high-purity materials. With a commitment to sustainable practices, Kumar Minerals employs advanced quarrying techniques, including selective blasting and eco-friendly processing, to minimize environmental impact while maximizing resource recovery.
Our operations span multiple sites, featuring state-of-the-art sorting facilities that yield quartz lumps (typically 10-100 mm) and blocks (over 100 mm) with silica content exceeding 98%. These products are renowned for their low iron and alumina impurities, making them suitable for demanding industrial applications. We supply across India ,serving clients with flexible order sizes from small batches to bulk shipments.
End Uses
Quartz and quartzite from our mines find extensive applications across industries. In glass manufacturing, high-purity lumps serve as a key raw material for producing flat glass, container glass, and specialty glassware due to their clarity and thermal stability. Ceramics and Pottery Industries utilize these minerals for tiles, sanitaryware, and refractories, where quartzite blocks provide strength and heat resistance. In construction, crushed quartzite acts as durable aggregate in concrete, road base, and architectural stone, enhancing structural integrity. The foundry sector employs lumps in molds and cores for metal casting, while electronics and semiconductors benefit from ultra-pure grades in silicon wafer production. Additionally, quartz blocks are popular in countertops, flooring, and decorative facades for their aesthetic appeal and hardness. Emerging uses include solar panel substrates and water filtration media, aligning with sustainable tech demands.
Kumar Minerals continues to innovate, investing in R&D for value-added products like micronized quartz powder, solidifying its role in India’s mineral economy.
