The countries with the largest reported antimony reserves are China (830,000 metric tons), Russia (350,000 metric tons), Bolivia (310,000 metric tons). Source: USGS Mineral Commodity Summaries 2026.

Who are the largest global producers of antimony?

Among 840+ producers tracked on TSM Hub, the largest disclosed antimony producers include Mandalay Resources Corporation (Canada), Sun Metals Corp. / Mandalay (Costerfield, Australia) (Australia), Bolkar Madencilik (Turkish antimony operations) (Turkey). Some operating antimony producers do not publish metal-specific tonnage — such as Bolkar Madencilik (Turkish antimony operations) (Turkey), Hsikwangshan Twinkling Star Co., Ltd. (China), Hunan Huaxing Nonferrous Holdings Co., Ltd. (China) — and are listed with an “Undisclosed Output” badge instead of a rank, in line with our principle of never inventing numbers absent from primary sources. Full ranking with primary-source links is available in the producers section.

Where can I find official antimony price data?

Official antimony prices are published by Spot. TSM Hub aggregates these feeds under licensed market-data redistributor agreements and updates them twice daily.

What is the primary source for antimony production and reserves data?

Country-level antimony production and reserves figures on TSM Hub are sourced directly from the USGS Mineral Commodity Summaries 2026, the U.S. Geological Survey's authoritative annual reference. Company-level production figures come from each producer's official annual report, production report, or regulated exchange filing.

Silicomanganese (SiMn) — Prices, Production, Reserves, Producers

TSM does not display real-time SiMn quotes on this page — instead, we link directly to the regulated exchanges and benchmark price-reporting agencies (PRAs) that produce the actual numbers. One True Source for All: where the data originates, that is where you should read it.

What is silicomanganese?

Silicomanganese (SiMn) is an iron-silicon-manganese ternary alloy carrying typically 65-68% Mn, 14-21% Si and 1.5-3% C. It is produced in submerged-arc electric furnaces from manganese ore + quartz + coke. SiMn is preferred over FeMn whenever the steelmaker also needs silicon deoxidation in a single addition (most carbon and low-alloy steel grades). Per International Manganese Institute (IMnI), global SiMn production is approximately 16-18 Mt/yr — substantially larger than the ~6 Mt/yr of high-carbon FeMn, making SiMn the single largest-tonnage ferroalloy on Earth.

How SiMn is priced

SiMn has no regulated futures contract. Pricing is by daily/weekly assessment from Fastmarkets, Argus, Platts / S&P Global and SMM — published as in-warehouse Rotterdam (US dollars per metric ton, Mn-content basis), CIF Japan/Korea/SE Asia and US Gulf assessments. Large contract tonnage is negotiated quarterly between integrated producers (Eramet, South32, Assmang, ChEMK) and major rebar/HRC mills. SiMn price tracks the manganese ore market more directly than FeMn does, because SiMn furnaces accept lower-grade ore.

Where SiMn is produced

SiMn production is concentrated in China (~60-65% of world tonnage, supplying domestic rebar/HRC mills), India, Ukraine (historically Nikopol, disrupted post-2022), Norway (Eramet Sauda, TIZIR Tyssedal), Russia (ChEMK, Mechel Bratsk), Malaysia (OM Sarawak), South Africa (Assmang Cato Ridge, Metalloys), Georgia and Brazil. Per USGS MCS 2026 Manganese, US apparent SiMn imports in 2025 were ~310 kt — the import source basket largely overlaps with FeMn.

Who produces SiMn

The SiMn producer base overlaps significantly with FeMn (most smelters can swing between the two):

Eramet — Sauda (Norway), Moanda + Comilog (Gabon, integrated mine-to-alloy).
South32 — Metalloys (South Africa), TEMCO (Tasmania).
Assmang — Cato Ridge (South Africa).
OM Holdings — OM Sarawak (Malaysia).
ChEMK / Челябинский электрометаллургический комбинат — Russia, largest ferroalloy producer in CIS.
Mechel — Bratsk Ferroalloy Plant (Russia).
Maithan Alloys — India (one of the largest Indian SiMn producers).
Tsingshan and other Chinese smelters — fragmented domestic base feeding SHFE-linked rebar/HRC mills.

What SiMn is used for

SiMn is the workhorse deoxidant-plus-alloy addition for carbon and low-alloy steelmaking — particularly for long products like rebar and wire rod where both Mn and Si are required in the finished steel. A single SiMn addition replaces two separate FeMn + FeSi additions, simplifying ladle metallurgy. SiMn consumption tracks rebar production directly, which is why Chinese SiMn output is roughly proportional to SHFE rebar futures volumes. Roughly 90% of SiMn flows into carbon steel; the remainder feeds alloy and tool steels.

Key facts about SiMn supply

SiMn is the single largest-tonnage ferroalloy globally (~16-18 Mt/yr) — ahead of FeMn (~6 Mt), FeCr (~13 Mt), FeSi (~9 Mt) and FeNi/NPI combined.
Manganese is on the USGS 2025 Critical Minerals list; the EU lists battery-grade Mn as a Strategic Raw Material.
The Ukrainian SiMn industry (Nikopol, Stakhanov) was historically a top-5 global producer; output has been materially disrupted since 2022.
