Global iron ore production has increased from 2.9 billion tonnes in 2012 to 3.3 billion tonnes in 2016, peaking at 3.38 billion in 2014.
get priceBauxite. The primary ore of aluminum, this mineral is known as "solid electricity," in allusion to the amount of energy it takes to process the ore. This is why aluminum is so highly sought-after for recycling. The mineral is a mixture, and rock, comprised of iron and aluminum hydroxides/oxides. It was named after the locality at Baux, France.
get priceBauxite is the principal aluminum ore consisting of a mixture of minerals, namely gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), and the iron oxides goethite and hematite. It can also contain smaller amounts of the clay mineral...

get priceBauxite ore requires at least an iron pickaxe to break. Due to this, it is possible to tell bauxite from iron by trying to break it with a stone pickaxe, as bauxite can't be broken with it while iron can. The color is slightly different as well; bauxite ore is a little more dull than iron ore.
