Our industrial minerals — quartz powder, feldspar, dolomite, and quartz grit — are essential inputs across a wide spectrum of global industries.
Feldspar and quartz powder are fundamental raw materials in the production of ceramic tiles, sanitaryware, tableware, and technical ceramics. Feldspar acts as a flux, lowering the vitrification temperature and improving the mechanical strength and translucency of ceramic bodies. Quartz powder provides structural integrity and dimensional stability during firing. PIME supplies both potash feldspar and soda feldspar in ceramic-grade mesh sizes, along with quartz powder optimised for ceramic body formulations.
Quartz powder and feldspar are primary raw materials in all types of glass production — from flat and float glass to container glass, fibreglass insulation, and specialty optical glass. Silica provides the glass-forming oxide, while feldspar contributes alkali fluxes that lower melting temperatures. PIME's quartz powder and feldspar products meet the stringent purity thresholds required by global glass producers, with low iron content to ensure colour fidelity in clear glass applications.
Micronised quartz powder acts as a functional filler and extender in paints, industrial coatings, sealants, and adhesives. It improves scratch resistance, reduces shrinkage, enhances viscosity, and reduces cost while maintaining performance. PIME's quartz powders are available in multiple fineness grades (up to 1250 mesh) with high brightness and whiteness values, making them ideal for both high-performance industrial coatings and architectural paint formulations.
The semiconductor and photovoltaic industries demand ultra-high purity quartz as a critical feedstock. Quartz grit with SiO₂ purity of 99.90% to 99.99% and electrical conductivity below 5 µS/cm is used to produce quartz crucibles, diffusion tubes, and other components in chip fabrication and solar cell production. PIME's electronics-grade quartz grit meets the ultra-low trace element specifications required for these demanding technology applications.
Quartz powder is the primary component in engineered quartz stone used for kitchen and bathroom countertops, vanity tops, and architectural surfaces. The high purity and consistent whiteness of PIME's quartz powder ensures uniform colour and durability in finished slabs. We supply multiple mesh grades optimised for engineered stone manufacturers who require reliable colour consistency and structural performance.
Ultra-fine dolomite powder is used in cosmetics and personal care formulations as a gentle mineral filler. Its natural whiteness and softness make it suitable for face powders, body talcs, and skincare products. Dolomite also finds application in health supplements as a natural source of calcium and magnesium. PIME supplies cosmetic-grade dolomite processed to 635 mesh with controlled particle size distribution.
Dolomite powder is widely used in agriculture as a soil conditioner and pH regulator. It supplies essential calcium and magnesium while neutralising acidic soils, improving nutrient uptake, and promoting healthier crop growth. PIME supplies agricultural-grade dolomite in bulk volumes for large-scale farming operations and horticultural applications.
Graded quartz grit and dolomite powder serve critical roles in water treatment. Quartz grit acts as a physical filtration medium in municipal and industrial systems, while dolomite helps remineralise and adjust pH in treated water. PIME can supply graded filter media in various mesh sizes to suit different filtration system specifications and flow rates.
Quartz grit and quartz powder are used to create moulds and cores for metal casting in the automotive, aerospace, and heavy engineering sectors. The material must exhibit precise thermal stability, good binding properties, and consistent sizing. PIME supplies foundry-grade quartz products with controlled grain fineness to match specific casting requirements.
Both potash and soda feldspar are essential components in ceramic glazes and vitreous enamels, providing flux and contributing to gloss, smoothness, and durability of the finished surface. Feldspar is also used in abrasive formulations where controlled hardness is required. PIME supplies feldspar in the precise mesh sizes needed for glaze and enamel manufacturing.
Dolomite powder serves as a reinforcing filler in rubber compounding, improving tensile strength and abrasion resistance. In detergent manufacturing, it acts as a builder and filler. In steel and iron production, dolomite is used as an industrial flux material. PIME's high-grade dolomite is processed for consistent quality across these diverse industrial applications.
High-purity quartz grit is used as proppant material in hydraulic fracturing operations and as a component in specialised drilling fluids. The crush resistance and chemical stability of quartz grit make it suitable for downhole applications where durability under extreme pressure is essential.
