The most common agglomeration technique is pelletization, which requires the use of binders to hold the iron oxide grains together so that the agglomerates can be sintered into high-strength pellets. Although bentonite clay is the most commonly used binder, there are many other possibilities that could be competitive in a number of situations.

A binder for use in agglomerating finely divided iron ore materials, e.g., concentrates, is prepared from an iron-bearing material known on the Mesabi Range of Minnesota as ''''paint rock.'''' This is a red or orange, fairly soft and extremely sticky mineral consisting essentially of hematite, kaolinite and quartz, and having a high-ignition loss and high-moisture content.

A particularly promising approach is the iron nugget process, where pellets are made that consist of iron oxide concentrate, powdered coal, flux, and a binder. When these pellets are heated, they self-reduce to form metallic iron droplets that separate from the slag.

There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.
