Largest mining companies: the top 14 by mining revenue, plus the biggest US mine operators

This list is for suppliers, service firms, sellers and analysts who need to know which mining companies are biggest and where their people work. The first table ranks companies by revenue from mining in their latest annual report filed or published by 30 October 2026. The second uses the Mine Safety and Health Administration's mine data to rank the largest employers at US mines, which is often the more useful list for anyone selling equipment, safety or services.

The 14 largest mining companies by revenue

Revenue is as each company's 10-K, 20-F, 40-F or annual report states it, in US dollars except Teck, which reports in Canadian dollars; we converted at the Federal Reserve's 2025 average of 1.3973 Canadian dollars per US dollar (G.5A, 5 January 2026). Headquarters are the principal office in each filing. Employee counts exclude contractors unless stated.

Rows that need a note:

• Glencore reported $247.5 billion in total for 2025, of which its marketing (trading) business accounted for $219.6 billion. We rank its industrial activities, the mines, smelters and refineries, at $61.3 billion. The two segments add up to more than the group total because sales between them are eliminated.
• BHP and Fortescue report years to June 30, 2026. BHP's copper revenue rose $6.5 billion to $29.0 billion, overtaking iron ore as its largest business.
• Fortescue (16,966 million) and Barrick (16,956 million) are within $10 million of each other, for fiscal years that end six months apart.
• Alcoa mines bauxite but earns most of its revenue from alumina and aluminum, so it sits between mining and metals.
• Peabody is included because coal mining is its whole business; it mined more US coal than anyone in 2025 (see the MSHA table below).

Not ranked: Chinese and Indian miners such as Zijin Mining, China Shenhua and Coal India publish results in yuan or rupees through filings in Hong Kong, Shanghai and Mumbai that we didn't open for this list, and Codelco and Grupo México (Southern Copper's majority owner) report outside the SEC. Check their own reports before assuming they rank below the companies in the table.

The largest mine operators in the US

Every US mine reports its employees and hours worked to the Mine Safety and Health Administration (MSHA) each quarter. Grouping 2025 reports by each mine's current controller gives this ranking:

Source: MSHA Mines and Annual Employment/Production data sets (files of 23 October 2026), our sum of 2025 average employees across each controller's mines and subunits, including office workers at mine sites. Contractor employees are reported separately and are excluded.

Across all US mines, operators reported an average of 225,668 employees in 2025: 182,585 at metal and nonmetal mines and 43,083 at coal mines, which produced 527.7 million tons of coal. Open pits and quarries employed 99,742 and underground mines 31,399, with the rest in mills, preparation plants, offices and other surface work.

Two things stand out. Peabody mines more coal than anyone (100.2 million tons in 2025) with fewer workers than Core Natural Resources (90.3 million tons), because 93.1 million of Peabody's tons came from surface mines, against 50.9 million of Core's. And the aggregates companies run hundreds of small quarries each, so they buy differently from a copper miner with a dozen large sites.

How we built the list

1. Who counts. Companies whose main business is mining metals, minerals or coal. Glencore is ranked on its industrial segment and Alcoa on total sales. Aggregates and cement companies are left out of the revenue ranking but appear in the MSHA table.
2. What's counted. Revenue as reported for the latest fiscal year, from the income statement or segment note.
3. Currency. Federal Reserve 2025 annual averages for the one converted figure.
4. Checking. Every revenue figure was matched to the filing. Many top results for this search rank by market value, which moves daily, or quote Glencore's trading revenue as if it were mining. Wikipedia's list and investor sites like Visual Capitalist and Investopedia use their own dates and measures.
5. MSHA caveats. The controller is the company MSHA lists today, so a mine sold during 2025 counts under its new owner. Joint ventures appear under every controller MSHA names.

What the list is good for if you sell B2B

Sell to the mine, not just the headquarters. General guidance, not drawn from the filings. Mining companies buy most operating spend at site level: haul trucks and parts, explosives, tires, conveyor belts, safety equipment and contractor services are usually chosen by the mine's maintenance, operations and safety leaders, with corporate procurement setting frame agreements. A company with 12 large mines and one with 300 quarries need very different coverage plans.

Use the federal data for territory planning. MSHA's mine data gives every mine's location, commodity, operator and headcount, which is a ready-made account list for a territory. Our guide to building a prospect list covers how to turn a dataset like this into named accounts.

Watch commodity cycles. Copper and gold revenue rose sharply in 2025 and 2026 while coal fell (Peabody's revenue was down 8.9%). Miners with rising cash flow approve projects and replacement equipment; those with falling prices cut costs, which favors suppliers who can show savings.

Worked example

Illustrative example. Beltwise (beltwise.example) sells conveyor belt monitoring at an illustrative $30,000 a year per site. Its seller sizes the US aggregates market from MSHA data:

• Start: the three largest aggregates controllers run 254, 337 and 398 mines with employees, 989 in total.
• Filter: assume an illustrative 30% have conveyors long enough to justify monitoring: about 297 sites.
• Market: 297 x $30,000 = about $8.9 million a year from three companies.

Rather than pitch headquarters first, the seller picks one region where all three operate, wins a pilot at five quarries with the regional operations manager, and uses the savings to reach the corporate procurement team. Finding the regional leaders and which quarries are expanding is the slow part; Bebop researches each account in a list like this.
