Iron Ore Pellets
Small, spherical balls of processed iron ore, agglomerated to a specific size and iron content for use as blast furnace or direct-reduction furnace feedstock.

Overview
Iron ore pellets are small, hardened balls of ore, typically 9 to 16 millimetres across, made by rolling fine ore or concentrate with a binder and then firing it at high temperature to fuse the particles into a durable, uniform sphere. They sit at the high-value end of the iron ore product range: pellets are more consistent in size and iron content than lump or fines, handle and ship well without breaking down into dust, and can be used directly in both traditional blast furnaces and the newer direct-reduction (DRI) processes that fines and lump generally can't feed without an intermediate agglomeration step of their own.
How It's Manufactured
Pellet production, called pelletizing or induration, starts with finely ground iron ore or concentrate, mixed with a small amount of binder — commonly bentonite clay — and water to help the particles stick together. This mixture is fed into rotating drums or discs that roll it into small, roughly spherical 'green' pellets, still soft and easily crushed at this stage. The green pellets then travel through an induration furnace, dried and fired at temperatures around 1,200-1,350°C, hardening them into the strong, durable pellets that can withstand shipping, stockpiling and the mechanical stresses inside a blast furnace or DRI shaft without breaking apart.
Byproducts
Pelletizing generates process dust and flue gas from the induration furnace, which plants capture and control with scrubbers and dust collectors, both for environmental compliance and because unrecovered fine ore is lost product. Because pellet plants typically draw on concentrate as their feedstock, much of the tailings and waste-rock burden associated with pellets was already generated upstream during beneficiation rather than at the pelletizing step itself. Off-specification or crushed pellets — material that doesn't meet size or strength requirements — is usually recycled back into the front of the process rather than discarded, since it's still perfectly good iron ore.
Who Consumes It
Pellets are bought by integrated steel mills running blast furnaces, and increasingly by the growing number of steel producers adopting direct-reduction technology, since DRI plants generally require pellets or lump rather than fines. Major pellet producers — Vale in Brazil, LKAB in Sweden, Iron Ore Company of Canada, and large Indian and Ukrainian producers — sell mainly to steelmakers in Europe, the Middle East, and Asia, regions where DRI adoption and stricter furnace-efficiency requirements have made pellet demand grow faster than for lump or fines in recent years.
Everyday Uses
As with other iron ore forms, pellets don't reach consumers directly, but their high, consistent iron content and efficient furnace performance make them a preferred feedstock for the steel that ends up in appliances, vehicles, packaging and construction. Pellets are especially associated with premium, more consistent steel grades, since a stable furnace feed makes for a more predictable, controllable smelting process, which downstream translates into steel with fewer quality variations for manufacturers turning it into finished consumer goods.
Industrial Uses
Pellets are the standard feedstock for direct-reduction ironmaking, the process at the center of the steel industry's push toward lower-carbon production, since DRI plants are what most green hydrogen-based ironmaking projects are built around. That's making pellet demand grow faster than demand for lump or fines as more steelmakers, particularly in Europe and the Middle East, invest in DRI capacity to cut emissions. Beyond DRI, pellets remain a major blast-furnace input in their own right, valued for the size uniformity and mechanical strength that let furnace operators run more efficiently, use less coke, and produce a more stable furnace throughput than a fines- or lump-heavy charge allows.

Steel's Green Shift Could Run Into a 133-Million-Tonne Iron Ore Shortfall by 2040
As steelmakers move away from blast furnaces to cut emissions, BloombergNEF projects a 133-million-tonne annual shortage of the high-purity iron ore pellets those newer processes need by 2040.
