important lithium ore mineral. A typical run of mine ore can contain 1-2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). Higher grade concentrates with 7.6% Li 2 O and low iron content are used in ceramics and more demanding industries.

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.

How iron ore pellet is made – the pellets manufacturing process. Iron ore pellets are a man-made iron-riched ore. The pellet production method was invented in Sweden in 1912, and then began to be used in the United States in 1946 by shaft furnace. It was originally developed primarily for the efficient use of taconite mines.
