About Aurum Mintek Pvt. Ltd. - Quartz Supplier in India

Based in India, Aurum Mintek Pvt. Ltd. lists 19 active mineral products across quartz, feldspar and silica sand categories. The catalogue comprises various quartz forms such as A‑grade grits, B‑grade powders and natural lumps, together with sodium and potash feldspar variants. Products are classified under HS Chapter 25, primarily HS 2505.10 and HS 2506.10, reflecting quartz sand and quartz stone respectively. The supplier’s portfolio also includes silica sand identified as high‑purity quartz SiO₂ with typical purity above 98 %.

The listed quartz items cover size fractions from 0.6‑1.2 mm (30‑16 #) up to 2.5‑4.0 mm (8‑5 #) and powders finer than 0.1 mm (<140 #). Both A and B grades are identified, where A grade denotes ≥98 % SiO₂ and B grade may contain iron oxides or clay. Feldspar products include sodium feldspar (Albite) under HS 2529.10 and potash feldspar (Orthoclase) under HS 2529.29, with typical K₂O content of 9.2‑9.8 %. All entries reference the material composition as natural quartz or feldspar minerals.

Product Range and Specialties of Aurum Mintek Pvt. Ltd.

Within the quartz segment, Aurum Mintek offers A‑grade sand (≥98 % SiO₂) in three size ranges - 0.6‑1.2 mm, 1.2‑2.5 mm and 2.5‑4.0 mm - and B‑grade sand that may contain up to 2 % iron oxide or clay. Powder forms under 0.1 mm are supplied as both A and B grades, the latter commonly used for abrasive or filler applications. Feldspar listings comprise sodium feldspar (Albite) with Al₂O₃ around 17‑19 % and SiO₂ 66‑68 %, and potash feldspar containing 9.2‑9.8 % K₂O. These specifications align with the typical industrial standards for glass‑making, ceramics and paint pigments.

Globally, quartz sand for glass production is graded according to ICUMSA and ASTM D 4602, with A‑grade requiring ≤0.02 % iron and moisture below 0.1 %. Feldspar used in ceramics follows ISO 1302 for chemical composition and impurity limits. Buyers often request certificates of analysis confirming SiO₂ purity, loss on ignition and particle‑size distribution. Commonly accepted certifications include ISO 9001 quality management and SGS inspection reports. Export shipments are usually packed in 20‑ft or 40‑ft containers, bulk‑bagged in 25 kg or 1 ton poly‑propylene bags.

Trade and Export Information - Aurum Mintek Pvt. Ltd.

India is a major exporter of high‑purity quartz sand and feldspar, supplying glass manufacturers in the Middle East, automotive glass plants in Europe, and semiconductor‑grade silicon producers in East Asia. HS 2505.10 and HS 2506.10 items are subject to customs inspection for silica content and hazardous material declarations, especially when B‑grade material contains iron oxides. Buyers in the United States, EU and Southeast Asia typically require compliance with REACH (EU) or TSCA (US) and may request third‑party laboratory reports.

Standard export packaging for the listed products consists of multi‑layered polypropylene bags (25 kg) stacked on wooden pallets, or bulk‑bag (1 ton) for large orders, loaded into 20‑ft or 40‑ft containers under CIF or FOB terms. Documentation generally includes commercial invoice, packing list, certificate of origin, MSDS and, when requested, an ISO 9001 or SGS conformity certificate. Seasonal demand peaks during the glass‑manufacturing ramp‑up in Q1‑Q2, influencing lead times.

Sourcing from Aurum Mintek Pvt. Ltd. - Buyer Guidance

Prospective buyers should request a recent Certificate of Analysis that details SiO₂ purity, loss on ignition, iron oxide percentage and particle‑size sieve analysis for the specific quartz grade. For feldspar, the analysis should include Na₂O, K₂O and Al₂O₃ percentages. An up‑to‑date MSDS and proof of ISO 9001 certification are standard documents to verify product safety and quality management.

Before confirming an order, verify that the HS code on the commercial invoice matches the intended product (e.g., 2505.10 for quartz sand, 2506.10 for quartz stone, 2529.10 for sodium feldspar). Minimum order quantities are typically 1 metric ton per grade, and lead times range from 2 weeks for bagged shipments to 4‑6 weeks for bulk containers, subject to production scheduling. Requesting a small sample (e.g., 5 kg) for independent testing can help confirm compliance with the required specifications.

What quartz grades are available from Aurum Mintek?

Aurum Mintek supplies A‑grade quartz sand with ≥98 % SiO₂ in three size fractions (0.6‑1.2 mm, 1.2‑2.5 mm, 2.5‑4.0 mm) and B‑grade sand that may contain iron oxide or clay, as well as powders finer than 0.1 mm in both A and B grades.

Which HS codes correspond to the quartz and feldspar products?

Quartz sand and stone are classified under HS 2505.10 and HS 2506.10, while sodium feldspar uses HS 2529.10 and potash feldspar uses HS 2529.29.

What typical chemical specifications should I check for the quartz products?

For A‑grade quartz, SiO₂ purity should be 98 % - 99.5 % with iron oxide below 0.02 % and moisture under 0.1 %; B‑grade may have up to 2 % iron oxide and higher moisture content.

What documentation is recommended before purchasing?

Request a Certificate of Analysis, Material Safety Data Sheet, ISO 9001 quality management certificate and, if required by the destination market, an SGS inspection report or REACH compliance statement.

How are the products packaged for export?

The quartz and feldspar are typically packed in 25 kg polypropylene bags placed on wooden pallets for 20‑ft containers, or in 1‑ton bulk bags for larger shipments, with moisture‑resistant liners to protect purity.

What are the usual minimum order quantities and lead times?

Minimum order quantities are generally 1 metric ton per grade; lead time is about 2 weeks for bagged orders and 4‑6 weeks for full‑container bulk shipments.

Which industries commonly import these minerals from India?

Major importers are glass manufacturers, ceramics and tile producers, foundries, paint and coating companies, and electronics firms that require high‑purity silica for silicon wafer production.
