Coltan
The product offered by Geo Unearthed is a Columbite‑Tantalite ore concentrate with a measured 39.8 % Ta₂O₅ and the remainder primarily Nb₂O₅. The supplier states the combined Ta₂O₅/Nb₂O₅ content reaches approximately 60 % of the ore mass. Current inventory includes 40 metric tonnes ready for shipment, with a steady supply of 25 tonnes per month thereafter. The concentrate is packed in 25 kg polypropylene bags as described in the listing.
Coltan of this grade is commonly produced from primary mining operations and is a key input for tantalum capacitor manufacture and high‑temperature superalloys. Industry standards typically target Ta₂O₅ contents between 30 % and 50 % and Nb₂O₅ between 20 % and 30 % to meet electronic‑grade specifications. The 25 kg bag format aligns with bulk handling practices, though larger bulk shipments are often consolidated into 1‑tonne jumbo bags for ocean freight. Commodity‑level quality checks include XRF assay, moisture content below 0.5 % and impurity limits under 5 % for Fe, Si and Al.
Primary buyers are smelters and downstream processors in the electronics and aerospace sectors who require consistent tantalum supply. Geo Unearthed handles freight to the destination port and can arrange door‑to‑door delivery upon request, but Incoterms and payment terms must be agreed directly with the supplier. Prospective purchasers should confirm the latest assay report, packaging integrity and any required conflict‑free certification before placing an order.

Geo Unearthed operates from the United States, with its address listed as a United States location. It carries a harbour‑tier verification, yet its response rate is shown as 0 % and there is no recorded average response time, suggesting limited recent communication on the platform. The company specialises in supplying mineral concentrates for high‑tech and aerospace applications.
According to the listing, Geo Unearthed can deliver 40 metric tonnes of coltan immediately and sustain a monthly output of 25 tonnes, packaged in 25 kg bags and shipped to the buyer’s port. The supplier provides origin documentation and assay reports confirming conflict‑free status, but does not publish MOQ, lead‑time or payment terms, which should be clarified in direct negotiations.
We currently have 40 metric tons of coltan (columbite-tantalite) ore available for immediate shipment, with an ongoing supply of 25 MT per month. This mineral concentrate is sourced with full origin documentation and assay reports confirming both conflict-free status and consistent Ta2O5/Nb2O5 composition. We manage all logistics and shipping to your destination port, making this a turnkey procurement solution for smelters and processors in the electronics and aerospace supply chains.

Sourcing Coltan from Geo Unearthed - United States Import Guide
When sourcing coltan from Geo Unearthed, request the most recent XRF assay report and the accompanying Conflict‑Free Minerals Declaration to confirm the 39.8 % Ta₂O₅ level and the origin of the ore. Verify that the 25 kg polypropylene bags are sealed and meet your moisture‑control standards. Ensure the documentation satisfies any national or corporate mineral‑sourcing compliance requirements before placing the order.
Clarify the preferred Incoterm - for example FOB Ottawa or CIF New York - and identify the destination port that fits your distribution network. Although the supplier does not state a specific lead‑time, bulk shipments of 25 kg bags typically require two to three weeks for inland transport to the port, followed by four to five weeks of ocean freight to Asian destinations. Agree on payment method, such as a confirmed letter of credit, to protect both parties.
Schedule a pre‑loading inspection at the supplier’s warehouse to check bag integrity, moisture content below 0.5 % and bulk density within the 3.2‑3.5 t/m³ range. Obtain a certificate of analysis for each container and keep the original paperwork for customs clearance and quality assurance. Upon arrival, conduct a random sample test to verify that the Ta₂O₅ and Nb₂O₅ levels meet the specifications before releasing payment.
