The undiminished demandof iron oreleads to mining of even lowervalued deposits the reduced quality of the natural resources stands in opposition to the economic ecological and technological restrictions which require an intensivemineral processingof theiron ore
The smelting process allows the iron ore to be heated with carbon the carbon combines with the oxygen and carries it away leaving behind iron blast furnaces are so hot which is why they melt the iron and drain it off to be poured into moulds to form bars called ingots
The ores are extracted by mining for a profit from the earth they are then refined often by smelting in order to extract the valuable elements the ore quality and density of a rock or metal ore as well as its occurrence type can directly affect the ore mining costs
