Beneficiation and Concentration
Facts checked against sources on . How we check facts.
Beneficiation turns mined ore into a concentrate, the traded product that smelters and chemical plants buy, and concentrate prices are among the most volatile in the supply chain. USGS reports that the Rotterdam tungsten concentrate price averaged $380 per metric ton unit in 2025, up 51% from $252 in 2024, while manganese ore fell 19% to $4.50 and zircon fell 10%. Many mines sell concentrate abroad: the Eagle Mine in Michigan produced about 10,000 tonnes of nickel in concentrate in 2025 and exported all of it to smelters in Canada and overseas.

What do concentrates sell for, and how much do prices move?
The table lists the concentrate and ore prices USGS reports for 2021 to 2025. Percentage changes for 2025 are our arithmetic.
| Product | Unit | 2021 | 2022 | 2023 | 2024 | 2025e | 2025 vs 2024 |
|---|---|---|---|---|---|---|---|
| Tungsten concentrate, Rotterdam | $ per metric ton unit of WO3 | 225 | 275 | 258 | 252 | 380 | +51% |
| Tantalite | $ per kg of Ta2O5 | 158 | 196 | 170 | 167 | 180 | +8% |
| Ferroniobium (import unit value) | $ per kg | 21 | 25 | 25 | 26 | 26 | 0% |
| Chromite ore | $ per metric ton | 199 | 277 | 321 | 331 | 290 | -12% |
| Manganese ore, c.i.f. China | $ per metric ton unit of Mn | 5.27 | 5.97 | 4.80 | 5.53 | 4.50 | -19% |
| Zircon, premium, c.i.f. China | $ per metric ton | 1,530 | 2,300 | 2,160 | 2,000 | 1,800 | -10% |
| Vanadium pentoxide | $ per pound | 8.17 | 9.29 | 7.50 | 5.44 | 5.02 | -8% |
Source: USGS Mineral Commodity Summaries 2026 salient statistics for tungsten, tantalum, niobium, chromium, manganese, zirconium and vanadium. Vanadium pentoxide is a chemical intermediate rather than a concentrate. Within 2025 the Rotterdam tungsten concentrate price rose from $266 to $551 per metric ton unit.
Where does concentrate go next?
Concentrate usually leaves the mining country, so beneficiation and the next step are often in different places. USGS records that the Eagle Mine's nickel concentrate went to Canadian and overseas smelters, that the Michigan platinum group metals were exported for refining, and that tellurium recovered as copper telluride at two U.S. copper refineries was exported for further processing. Rare earths are the exception among these: bastnaesite was mined at Mountain Pass and rare earths were "mined and processed domestically" in 2025, with 51,000 tonnes of oxide in concentrates valued at $240 million. That works out at about $4.70 per kilogram of oxide in a mixed concentrate, which is not comparable with separated oxide prices such as $69 per kilogram for neodymium-praseodymium; the gap is the value added by separation (see the separation page).
What stays with the concentrate buyer?
The buyer of a concentrate takes the processing risk and most of the value added. The chemical step is covered on the chemical processing page, where China's share of processing is shown to be far larger than its share of mining for several minerals. Fixed concentrate prices are uncommon in the data above; the pricing page shows how contracts and floors are set.
Frequently asked questions
What is beneficiation?
Beneficiation is the processing that upgrades mined ore into a higher-grade concentrate that can be sold to a smelter or chemical plant. Examples in the USGS data are nickel concentrate, copper telluride, bastnaesite concentrate, zircon and tungsten concentrate.
How volatile are concentrate prices?
Very. USGS reports the Rotterdam tungsten concentrate price rose from $266 to $551 per metric ton unit during 2025, while the 2025 annual average manganese ore price fell 19% and chromite ore fell 12% compared with 2024.
Is mined concentrate processed in the country where it is mined?
Often not. The Eagle Mine in Michigan exports its nickel concentrate to smelters in Canada and overseas, the Michigan platinum group metals are exported for refining, and U.S. copper telluride is exported for processing. U.S. rare earth concentrate was processed domestically in 2025.
What is a metric ton unit?
A metric ton unit is one percent of a metric ton of contained metal oxide or metal, used to price concentrates such as tungsten (WO3) and manganese ore. Prices in the USGS tables are quoted per unit, so a higher grade of concentrate carries more units per tonne.
