Prices & Buying by Metal Content

The price of Tantalum is subject to fluctuations on international commodity exchanges. Since residues are rarely in absolutely pure form, we do not calculate the purchase price as a flat rate, but on the basis of the net metal content determined precisely through lab analysis.

Material Category	Typical Supply Form	Minimum Purity	Indicative Price / Price Range	Calculation Note
Solid tantalum scrap	Sheets, rods, cut-offs	> 99,9 %	200,00 € – 350,00 €	Settlement per kg net weight after visual/XRF check.
Tantalum powder & sintered powder	Powder, sintered powder, anode residues	> 99,5 %	170,00 € – 380,00 €	Price factor: homogeneity, freedom from foreign metals.
Tantalum scrap & turnings	CNC turnings, cut-offs, mixed scrap	variable	80,00 € – 200,00 €	Deduction for moisture, coolant oils and tool wear (Fe).
Tantalum capacitors	Single-grade SMD / tantalum drop	by component type	110,00 € – 200,00 €	Sorted by MnO₂, polymer or wet tantalum type (highest value).
Tantalum sludges / condensate	Grinding residues, furnace deposits	variable matrix	After lab digestion	Settlement after thermal drying and ICP-OES analysis.

The purchase prices shown are indicative only. The actual purchase price depends on purity, metal content, analysis, material form, quantity, and current market conditions. After the goods are received, we provide a free valuation and an individual offer.

What Determines the Purchase Price for Tantalum?

▸ Net Metal Content

The higher the percentage of pure Tantalum, the lower the deductions for smelting and refining.

▸ Impurities

Accompanying metals are valued metallurgically; interfering elements increase processing costs.

▸ Moisture & Organics

For sludges, the loss on ignition (share of water, oils, emulsions) determines the real dry weight.

▸ Batch Size (Quantity)

Larger quantities reduce the per-kilogram share of sampling and lab analysis costs.

▸ Market Conditions

The current world market price forms the basis of our calculation.

Precise Analysis = Maximum Payout

We determine the value of your batch using accredited lab methods: XRF, ICP-OES, and ICP-MS. Every complex batch receives a detailed lab report.

Case Studies

Higher Returns Through Process-Driven Material Separation

Example: Tantalum Capacitors from Electronic Scrap

Scenario A — Unsorted

▾Mixed electronic scrap
▾Direct thermal recovery
▾Revenue: 0 € (or disposal fees)

−1.500 €

Scenario B — The SYPRA Concept

▸Targeted dismantling of the tantalum capacitors
▸Separate processing of the circuit boards
▸Payment at the real high-end value

+3.000 € to +15.000 €

→ Higher returns through proper separation.

Tantalum Recycling & Raw Material Cycle

Tantalum is classified by the European Commission as a critical raw material. Recycling {name} residues closes material cycles, drastically reduces the CO₂ footprint of your production, and secures European companies' access to secondary raw materials. By selling your residues, you contribute to the circular economy.

Strategic Recycling Consulting for Industry, Production, and Waste Management

We don't just buy your material — we optimize your internal processes. Many industrial companies give away real money because they don't know the value of their production waste, or because valuable materials get lost in the disposal mix.

SYPRA supports industrial companies, recyclers, primary treatment facilities, and metal traders with:

▸ the systematic identification of hidden metal reserves in your waste and residue streams
▸ developing concepts for separate collection directly at your production lines (decentralized extraction systems for powders, separation of coolant and turnings)
▸ organizing independent umpire analyses (Schiedsanalysen) and metallurgical expert reports
▸ planning complex B2B recycling projects for rare metals to optimize your raw material flows

Frequently Asked Questions About Tantalum

How is the tantalum price per kg determined? +

The price is based on the exact net tantalum content, determined through laboratory analysis (XRF, ICP-OES). We pay for the pure metal fraction according to current market quotations, less processing costs.

Do you buy contaminated tantalum turnings or sludges? +

Yes. We buy powder, turnings, sludges, furnace deposits and alloys. Settlement is based on representative sampling, drying and determination of the metal content.

What is the minimum quantity for tantalum purchasing? +

Solid scrap and capacitors from approx. 10–20 kg. For high-purity powders or rare alloy cut-offs, we also analyze smaller quantities.

How long does tantalum analysis and settlement take? +

XRF screening of solid scrap on the day of delivery. ICP-OES for inhomogeneous sludges or powders: typically 3 to 5 business days.

About Us

SYPRA METALS — Strategic Metals Buyer Europe

Since 1990, SYPRA GmbH has been an internationally active trading company focused on Europe, Eastern Europe, and Central Asia. SYPRA METALS brings together the group's expertise in B2B buying, instrumental analysis, and the valuation of strategic metals — tantalum, tungsten, cobalt, niobium, hafnium, gallium, indium, and other special metals in any supply form.

Who We Are

Our success is built on reliable partnerships between Europe and Central Asia. Over three decades, SYPRA has built lasting relationships with producers, recycling companies, and industrial end users.

SYPRA METALS is the central platform for the professional buying of strategic metals: powders, turnings, sludges, capacitors, alloys, and complex industrial residues — valued by real metal content, not flat scrap prices.

Recycling Instead of Downcycling — Preserving the Value of Raw Materials

Primary raw materials are finite. Through professional recycling, we recover high-quality secondary raw materials and reduce the need for energy-intensive primary extraction.

Our standard is high-quality recycling: through careful sorting, analysis, and processing, metals are reintroduced into industrial production processes — with as little quality loss as possible.

Our Mission — Responsibility in the Raw Materials Cycle

Recycling strategic metals is today a decisive contribution to climate protection, human rights, and biodiversity. We close material cycles for European industrial companies.
