Our fine tin slag is carefully processed and serves as an excellent secondary source for extracting critical refractory metals. **Key specifications** - **Ta₂O₅ (Tantalum Pentoxide):** Available on request - **Nb₂O₅ (Niobium Pentoxide):** Available on request - **Sn (Tin):** Available on request **Physical properties:** Fine granular particulate; dark grey to black. **Applications** - Primary feedstock for the extraction of Tantalum and Niobium - Utilized in the production of superalloys and advanced electronics **Packaging:** 1-Ton Jumbo Bags or customized export packaging. **Origin:** Malaysia. ### Ilmenite A premium titanium-iron oxide mineral sourced from high-quality Malaysian tailings. Our Ilmenite offers consistent titanium dioxide purity, making it ideal for large-scale industrial processing. **Key specifications** - **TiO₂ (Titanium Dioxide):** 50% – 54% - **Fe₂O₃ (Iron Oxide):** Available on request **Physical properties:** Fine sand; opaque, iron-black to brownish-black. **Applications** - Manufacturing of Titanium Dioxide (TiO₂) pigments for paints and coatings - Production of welding rod coatings and titanium metal sponge **Packaging:** 50kg bags or 1-Ton Jumbo Bags. **Origin:** Malaysia. ### Monazite A phosphate mineral containing a rich concentration of Rare Earth Elements (REEs). InterWestma ensures strict regulatory compliance through the Department of Atomic Energy Malaysia for the safe handling and export of this material. **Key specifications** - **TREO (Total Rare Earth Oxides):** Available on request - **ThO₂ (Thorium Dioxide):** Available on request **Physical properties:** Granular sand; reddish-brown to pale yellow. **Applications** - Crucial feedstock for the extraction of light rare earths (Cerium, Lanthanum, Neodymium) used in high-performance magnets, optics, and catalysts **Packaging:** Secure, radiation-compliant export packaging as per international standards. **Origin:** Malaysia. ### Tantalite, Struverite & Columbite A highly sought-after group of heavy minerals recovered from amang. These ores are globally recognized for their dense concentrations of tantalum and niobium, essential for modern technology sectors. **Key specifications** - **Ta₂O₅:** Available on request - **Nb₂O₅:** Available on request - **TiO₂:** Available on request **Physical properties:** Sub-metallic luster; dark brown to black particulates. **Applications** - Manufacturing of high-reliability tantalum capacitors for consumer electronics, automotive systems, and aerospace superalloys **Packaging:** 50kg steel drums or 1-Ton Jumbo Bags. **Origin:** Malaysia. ### Wolframite A primary ore of tungsten, offering exceptional hardness and high-temperature resistance. Our Wolframite is meticulously concentrated to meet the stringent demands of the metallurgy industry. **Key specifications** - **WO₃ (Tungsten Trioxide):** 65% min **Physical properties:** Heavy, crystalline structure; dark grey to brownish-black. **Applications** - Production of tungsten carbide for cutting tools and heavy machinery - Alloying agent in high-speed steel - Manufacturing of electrical contacts and filaments **Packaging:** 50kg bags or 1-Ton Jumbo Bags. **Origin:** Malaysia. ### Xenotime A premium rare-earth phosphate mineral. Unlike light-earth dominant ores, Xenotime is highly valued for its significant concentration of heavy rare earth elements, particularly Yttrium. **Key specifications** - **Y₂O₃ (Yttrium Oxide):** Available on request - **TREO:** Available on request **Physical properties:** Granular; yellowish-brown to reddish-brown. **Applications** - Extraction of Yttrium and heavy rare earths - Critical for manufacturing advanced phosphors (LEDs/displays), specialized ceramics, and microwave filters **Packaging:** Secure export packaging per buyer specification. **Origin:** Malaysia. ### Zircon Sand A naturally occurring zirconium silicate renowned for its exceptional chemical stability and high melting point. Our Zircon sand is thoroughly cleaned and processed to ensure minimal impurities. **Key specifications** - **ZrO₂ + HfO₂ (Zirconium Dioxide + Hafnium Oxide):** 65% min **Physical properties:** Fine, free-flowing sand; off-white to pale brown. **Applications** - Manufacturing of refractory bricks, foundry molds, and precision casting - Opacifier in the production of ceramic tiles and sanitaryware **Packaging:** 50kg bags, 1-Ton Jumbo Bags, or Bulk. **Origin:** Malaysia. > Grades vary per shipment. Where a specification reads "Available on request", > no assay figure is published - contact the company for current assay data > rather than quoting a figure. --- ## Operations & Quality Quality assurance, secure storage, and licensing underpin consistent export-ready shipments. ### Quality Control Sampling is conducted by internationally reputable companies: Alfred H.
