Michaela Brezinova supplies Coltan Ore sourced from verified mining operations in the Czech Republic. The product is a concentrate of Columbite‑Tantalite containing recoverable tantalum pentoxide (Ta2O5). The supplier describes the material as premium‑grade, suitable for downstream processing into electronic capacitors and alloy components. The listing notes that price and specific trade terms are negotiable.
Coltan ore is typically classified by its Ta2O5 content, with industry grades ranging from 30 % to 60 % by weight. The concentrate offered aligns with the higher end of this range, making it attractive for high‑performance applications. Particle size is generally milled to a maximum of 5 mm to facilitate efficient extraction, and moisture levels are kept low to preserve stability. Standard industry practice includes bulk packaging in sealed containers to prevent contamination.
Primary users include capacitor manufacturers, aerospace alloy producers and medical‑device component makers who require consistent tantalum feedstock. Buyers are expected to arrange bulk shipments under flexible Incoterms, with packaging suited to large‑volume transport. Interested parties should contact the supplier to confirm MOQ, lead time and payment conditions before placing an order.

Before committing to a purchase, importers should obtain a current assay report that details Ta2O5 concentration, particle size distribution and moisture level. Verification of the mining source and any applicable conflict‑minerals certificates is also essential to meet EU and US regulatory requirements. Requesting the supplier’s licence information and proof of legal extraction helps mitigate compliance risk. Confirm that the shipment will be accompanied by a material safety data sheet.
Logistics for bulk Coltan ore are usually organised under flexible Incoterms such as FOB or CIF, according to the buyer’s preference. As the supplier does not publish lead‑time figures, request an estimated production and dispatch schedule, particularly for orders exceeding a single container. Payment structures are negotiable and often involve a letter of credit or advance payment; confirming the exact terms in the contract safeguards both parties.
Quality assurance should include third‑party inspection of the ore upon arrival, focusing on Ta2O5 content, particle size and moisture as outlined in the assay report. Importers may engage an independent laboratory to perform a verification test before the cargo is released. Retaining all certificates, test results and shipping documents creates a clear audit trail for customs clearance and downstream processing.
