What Cleveland-Cliffs does and where it operates

Cleveland-Cliffs Inc. is a publicly traded iron ore mining and pellet production company based in Cleveland, Ohio. The company mines iron ore in the Upper Peninsula of Michigan and Minnesota, then processes it into iron ore pellets — the raw material that steel mills use in blast furnaces. Cleveland-Cliffs operates mines, pellet plants, and related infrastructure across the Great Lakes region, with its largest operations concentrated around the Mesabi Range in Minnesota and the Marquette Range in Michigan.

The company was formed in 2020 when Cliffs Natural Resources merged with AK Steel Holding Corporation. Before that merger, Cliffs Natural Resources had operated as an independent iron ore producer for decades. Today, Cleveland-Cliffs is the largest producer of iron ore pellets in North America and supplies pellets to integrated steel mills throughout the region, including mills operated by U.S. Steel, ArcelorMittal, and others.

Iron ore pellets are essential to steelmaking because they are easier to handle and more efficient to process than raw ore. Cleveland-Cliffs mines low-grade iron ore (called taconite), concentrates it, and forms it into pellets roughly the size of marbles. These pellets are then shipped by rail and water to steel mills, where they are melted in blast furnaces to produce molten iron for steel production.

Key Takeaways

  • Cleveland-Cliffs is the largest North American producer of iron ore pellets and operates mines and processing plants in Michigan and Minnesota.

Mining and pellet production process

Cleveland-Cliffs extracts iron ore through open-pit mining in the Mesabi and Marquette ranges. The ore mined in these regions is taconite, a low-grade iron ore that contains roughly 20 to 30 percent iron by weight. Raw taconite cannot be used directly in a blast furnace, so Cleveland-Cliffs operates concentration plants that crush the ore, separate the iron-bearing minerals from waste rock, and produce an iron concentrate.

The iron concentrate is then mixed with binders (typically bentonite clay) and formed into pellets in large rotating drums called pelletizers. These wet pellets are dried and hardened in traveling grate furnaces or shaft furnaces, producing finished pellets that are roughly 16 millimeters in diameter. The finished pellets are stockpiled, loaded onto rail cars or ships, and transported to steel mills.

Cleveland-Cliffs operates multiple pellet plants across its mining regions. The company's largest facilities include the Tilden Mine and Pellet Plant near Marquette, Michigan, and several operations on the Mesabi Range in Minnesota. Each facility is designed to process ore from nearby mines and ship pellets efficiently to customer mills via the Great Lakes or rail networks.

Supply contracts and customer relationships

Cleveland-Cliffs sells iron ore pellets under long-term supply contracts with integrated steel mills. These contracts typically specify the volume of pellets to be delivered over a period of years, the quality specifications the pellets must meet, and the price or pricing formula. Long-term contracts provide Cleveland-Cliffs with predictable revenue and allow steel mills to find a reliable source of raw material.

The company's largest customers are integrated steel mills in the Great Lakes region, including facilities operated by U.S. Steel, ArcelorMittal, and Nippon Steel. These mills depend on a steady supply of high-quality pellets to keep their blast furnaces running. Cleveland-Cliffs' geographic proximity to these mills — all within the Great Lakes shipping network — gives the company a significant cost advantage over overseas pellet producers.

Pellet prices are influenced by global iron ore markets, steel demand, and shipping costs. When steel mills reduce production due to weak demand, they order fewer pellets, which reduces Cleveland-Cliffs' revenue and may lead to temporary production cuts or workforce reductions. Conversely, strong steel demand increases pellet orders and production.

Employment and regional economic impact

Cleveland-Cliffs employs several thousand workers across its mining and pellet production operations in Michigan and Minnesota. Jobs include mine operators, equipment maintenance workers, pellet plant operators, quality control technicians, and administrative staff. Many of these positions are union jobs represented by the United Steelworkers (USW) or other labor organizations.

The company's operations support the broader regional economy in mining communities. Employees spend wages locally, and Cleveland-Cliffs purchases goods and services from regional suppliers. Mining and pellet production are capital-intensive industries, so the company also invests in equipment, facility maintenance, and infrastructure upgrades that create additional economic activity.

Employment levels at Cleveland-Cliffs fluctuate with steel industry cycles. During periods of strong steel demand, the company may hire additional workers or increase hours. During downturns, the company may reduce shifts, implement temporary layoffs, or close facilities temporarily. These cycles reflect the reality that pellet demand is entirely dependent on steel mill operations.

Environmental and regulatory considerations

Iron ore mining and pellet production are regulated by federal and state environmental agencies. Cleveland-Cliffs must comply with the Clean Air Act (for emissions from pellet furnaces and mining equipment), the Clean Water Act (for water discharge from concentration and pellet plants), and state mining regulations. The company operates under permits issued by the U.S. Environmental Protection Agency and state environmental agencies in Michigan and Minnesota.

Taconite mining generates large volumes of waste rock and tailings (fine particles left after iron concentration). Cleveland-Cliffs manages these materials in tailings basins and waste rock piles. The company must monitor and maintain these facilities to prevent environmental contamination and comply with state and federal standards.

Pellet production requires significant water and energy. Cleveland-Cliffs uses water in concentration and pellet-making processes and relies on electricity and natural gas for furnace operations. The company has invested in water recycling systems and energy efficiency improvements to reduce operating costs and environmental impact.

Market position and competition

Cleveland-Cliffs is the dominant pellet producer in North America, but it faces competition from foreign pellet producers and from steel mills that operate their own pellet plants. Some integrated steel mills produce their own pellets from ore they mine or purchase, which reduces their dependence on external suppliers like Cleveland-Cliffs. Additionally, some mills can substitute pellets with other iron-bearing materials, such as direct-reduced iron (DRI) or scrap steel.

Global iron ore producers, primarily in Australia, Brazil, and India, produce pellets and compete on price in international markets. However, Cleveland-Cliffs' proximity to Great Lakes steel mills and its access to the Great Lakes shipping network provide cost advantages that protect its market position for domestic supply.

The company's competitive position also depends on the health of the North American steel industry. If domestic steel production declines due to imports or reduced demand, pellet consumption falls, and Cleveland-Cliffs' revenue and production levels decline accordingly.

Ownership and financial structure

Cleveland-Cliffs is a publicly traded company listed on the New York Stock Exchange under the ticker symbol CLF. The company is owned by its shareholders, and its board of directors sets strategic direction. The company reports financial results quarterly and annually to the Securities and Exchange Commission (SEC).

As a capital-intensive business, Cleveland-Cliffs carries debt to finance mining equipment, pellet plant construction, and facility upgrades. The company's financial performance depends on pellet prices, production volumes, and operating costs. During strong steel demand periods, the company generates cash that can be used to pay down debt or invest in new capacity. During downturns, reduced revenue may limit the company's ability to invest or pay dividends.

Frequently Asked Questions

What is the difference between iron ore and iron ore pellets?

Iron ore is the raw mineral extracted from the ground; taconite ore mined by Cleveland-Cliffs contains only 20 to 30 percent iron. Iron ore pellets are processed and concentrated material formed into small balls, containing 60 to 70 percent iron. Steel mills prefer pellets because they are easier to handle, transport, and process in blast furnaces than raw ore.

Why do steel mills buy pellets from Cleveland-Cliffs instead of mining their own ore?

Some integrated steel mills do operate their own mines and pellet plants, but many find it more cost-effective to purchase pellets from specialized producers like Cleveland-Cliffs. Cleveland-Cliffs operates large, efficient facilities that achieve economies of scale, and the company's proximity to mills reduces transportation costs. Buying from an external supplier also allows mills to focus capital and management on steelmaking rather than mining.

How does Cleveland-Cliffs' business change when steel demand falls?

When steel mills reduce production due to weak demand, they order fewer pellets. Cleveland-Cliffs responds by reducing pellet production, which may involve temporary plant shutdowns, reduced work shifts, or layoffs. The company's revenue and profitability decline until steel demand recovers and mills resume normal production levels.

Is Cleveland-Cliffs the only pellet producer in North America?

No, but Cleveland-Cliffs is the largest. Some integrated steel mills produce their own pellets, and a few independent producers operate smaller facilities. However, Cleveland-Cliffs accounts for the majority of North American pellet production and is the primary external supplier to Great Lakes steel mills.

How are iron ore pellet prices determined?

Pellet prices are influenced by global iron ore markets, steel demand, transportation costs, and supply and demand for pellets specifically. Long-term contracts between Cleveland-Cliffs and steel mills often include pricing formulas tied to benchmark iron ore prices or include periodic price adjustments. Spot market prices for pellets also fluctuate based on short-term supply and demand conditions.
