Stamps were the most common way to crush ore for many decades, but by the first few decades of the 1900s the ball mill started replacing stamps. By the 1930s, many stamp mills were retrofitted with ball crushers, replacing the stamps that were originally used.
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
