Category Overview

Three Distinct
Minerals, One Source

The final category in GeoCore's portfolio covers three widely used industrial minerals with very different properties and applications. Soapstone (Talc) is one of the world's softest minerals — used in cosmetics, paints, and ceramics. Garnet is a hard, sharp natural abrasive used for waterjet cutting and sand blasting. Limestone is a sedimentary rock rich in CaCO₃ — the foundation of cement, construction aggregates, and agricultural lime.

◆Soapstone (Talc): Mg₃Si₄O₁₀(OH)₂ — Mohs hardness 1, available in industrial and cosmetic grades

◆Garnet: Mohs 6.5–7.5 — available in multiple mesh sizes for waterjet (80 mesh) and abrasive blasting (30/60 mesh)

◆Limestone: CaCO₃ 85–97% — cement grade, construction aggregate, and agricultural lime grades available

◆Pre-shipment lab testing, CoA, and full export documentation with every shipment

Soapstone (Talc)

Soapstone, or Talc, is the softest naturally occurring mineral on the Mohs scale (hardness 1). Its unique combination of softness, chemical inertness, heat resistance, and lubricating properties makes it indispensable across an unusually wide range of industries — from cosmetics and pharmaceuticals to paints, ceramics, and rubber. GeoCore Minerals sources industrial and cosmetic-grade Soapstone from established Indian deposits.

Garnet

Indian Almandine Garnet (Fe₃Al₂(SiO₄)₃) is one of the world's most exported natural abrasive minerals — prized for its hardness (Mohs 6.5–7.5), angular particle shape, and consistent grain size. These properties make it the preferred abrasive for waterjet cutting of metals, stone, and composites, as well as abrasive blasting and surface preparation for industrial and marine applications.

Limestone

Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO₃) — one of the most widely used industrial rocks in the world. It is the foundational raw material for cement production, used as a construction aggregate, added as a flux in steel blast furnaces, and applied as agricultural lime to adjust soil pH. GeoCore Minerals supplies Limestone in cement grade, industrial grade, and agricultural lime grades.

Industries We Supply

Where These Minerals
Are Used

Despite their very different properties, Talc, Garnet, and Limestone together serve an unusually broad range of global industries.

💄

Cosmetics & Personal Care

Talc's softness (Mohs 1) and chemical inertness make it the standard base mineral for face powders, body powders, and cosmetic foundations globally. Cosmetic grade requires low iron and asbestos-free certification.

Soapstone (Talc)

💧

Waterjet Cutting

80 mesh Garnet is the global standard abrasive for waterjet cutting of steel, aluminium, stone, glass, and composite materials. Angular particle shape and consistent hardness are the critical quality parameters.

Garnet (80 mesh)

🏭

Cement Manufacturing

Limestone is the primary raw material for cement — roughly 1.5 tonnes of limestone are consumed for every tonne of cement produced. High CaCO₃ content and consistent chemistry are essential for kiln operations.

Limestone

🎨

Paints & Coatings

Talc is used as a functional filler in architectural and industrial paints — improving film build, reducing settling, controlling gloss, and extending expensive titanium dioxide pigment.

Soapstone (Talc)

💨

Abrasive Blasting

Coarser Garnet (30/60 mesh) is used for abrasive blasting — cleaning steel structures, ship hulls, bridges, and industrial equipment. Garnet is preferred over silica sand due to lower silica dust health risks.

Garnet (30/60 mesh)

⚙️

Steel & Metallurgy

Limestone is used as a flux in blast furnaces to remove silica impurities from iron ore, producing slag. High-purity limestone (CaCO₃ 92%+) is preferred for metallurgical-grade applications.

Limestone

💊

Pharmaceuticals

USP-grade Talc is used as a tablet lubricant, anti-caking agent, and coating material in pharmaceutical manufacturing — subject to strict purity, asbestos-free, and pharmacopeial specifications.

Soapstone (Talc)

🌱

Agriculture

Agricultural Limestone (ground limestone / lime) is applied to acidic soils to raise pH, improve nutrient availability, and increase crop yields. One of the largest-volume agricultural inputs worldwide.

Limestone

🔵

Rubber & Plastics

Talc is used as a reinforcing filler and anti-block agent in rubber compounds and plastic films — improving stiffness, heat resistance, and dimensional stability in automotive and industrial rubber parts.
