Coltan Tantalum
Coltan Tantalum is a concentrate of Columbite-Tantalite (Coltan) that contains tantalum pentoxide (Ta2O5) in the range of 30-55 % by weight. The material is supplied as a bulk ore concentrate intended for downstream processing into high-capacitance tantalum capacitors. Marek Konopacki lists the concentrate as sourced from strategic mineral regions and handled in the United Kingdom. The product description notes its relevance to electronics, semiconductor, and defence sectors.
In the mineral market, electronic-grade coltan typically targets a Ta2O5 assay of 45-55 % with impurity limits for iron oxide below 5 % and moisture under 0.5 %. Standard processing assumes a bulk density around 3.5 g/cm³ and packaging in sealed 25 kg bags. Compliance with Conflict Minerals Reporting (CMR) and other due-diligence frameworks is a common requirement for buyers. The supplied concentrate meets these typical industry parameters, though specific certifications are not disclosed.
Manufacturers of smartphones, electric-vehicle power modules, and defence electronics rely on this concentrate to produce tantalum capacitors with high energy density. Importers should request assay certificates, material safety data sheets, and proof of conflict-free sourcing before purchase. The listing does not provide MOQ, lead time, or Incoterms, so prospective buyers must confirm these details directly with the supplier.

Sourcing Coltan Tantalum from Marek Konopacki - United Kingdom Import Guide
Before placing an order, verify the assay certificate that details the exact Ta2O5 percentage and impurity profile. Ask the supplier for a recent material safety data sheet and a conflict‑minerals compliance statement. Cross‑check the physical address and trust tier on the platform to ensure the supplier’s legitimacy.
Discuss the preferred Incoterm, such as FOB Merthyr Tydfil or CIF London, and obtain an estimated lead time for the bulk shipment. Shipping of coltan concentrate typically requires sealed bulk bags loaded into a container, with freight arrangements handled by a reputable carrier. Clarify payment terms, including any advance deposit and documentary letters of credit, before finalising the contract.
Arrange for an independent third‑party inspection at the loading port to confirm weight, density, and moisture content. Request laboratory assay results and a certificate of origin to satisfy downstream customers. Maintaining a record of all inspection reports and compliance documents will streamline customs clearance and downstream quality assurance.
