Iron and sulfur are converted to oxides and are removed in either the gas stream or the slag (the latter being recycled for the recovery of remaining values), leaving a " blister" copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Jun 30, 2016· Responding to the low iron ore price, Arrium Ltd's exploration for a future source of iron ore that can provide low-cost and low-capital requirements during mining and production has been focused near existing mine deposits (such as Camel Hills and Iron Warrior).
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
