Extracting iron from iron ore using a Blast Furnacemon ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
Iron ore is converted to iron by various processes. Themon process is the use of a blast furnace to extract pig iron. Pigprises of about 92 94 iron and about 3 5 of carbon along with other impurities. Pig iron has limited uses, so it is sent to steel plants where the content of carbon is

Copper can be extracted from its ore by: From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide removes some of the sulfur as sulfur dioxide This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air. The product from the
23/10/2018· Extraction of Iron from its ores Extraction of iron or its metallurgy is the process of obtaining this metal in a form where it can be put to practical use, and this process of extraction consists of three stages: Ore dressing, Reduction of ores and Iron production. Extraction of Iron from its ores
