The steps depend on the type of ore, the reactivity of the metal, and the nature of impurities present in the ore. These processes involved in the extraction and refining of the metal are called metallurgy. The ores of most of the metals should be brought to the Earth's surface for extracting metal from them. This process is called mining.

The impurities must be removed from the ore before the extraction of the metal. The processes used for removing the gangue from the ore are based on the differences between the physical or chemical properties of the gangue and the ore. Different separation techniques are accordingly employed. 1. Extracting Metals Low in the …
Extracting metals refers to the process of obtaining metals from their ores, which are rocks or minerals from which a valuable substance, typically metal, can be extracted. The process of extracting metals involves several scientific processes like roasting or calcinations, reduction, and refining.
Firstly carbon which is added along with crushed hematite ore is oxidized to C O and C O 2 and the second the produced C O acts as a chief reducing agent for the reduction of haematite to steel. Option D is correct.

Iron Ore Magnetic Separation - 911metallurgist. Apr 20, 2017· The largest development in the iron-ore industry, using magnetic concentration, is at the plants of Witherbee, Sherman & Co. at Mineville, N. Y., where about 1,200,000 tons of crude ore were mined and separated in 1916.
Question: Extraction of Metals Using the above summary for the extraction of iron, rank the common steps involved in the process of extraction of iron from its ore Rank the steps from first to last. To rank items as equivalent, overlap them.
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
The unit processes are usually characterized by certain chemical reactions such as roasting, leaching etc while unit operations are usually physical processes carried out discreetly on the ore. These physical processes are usually represented by crushing, grinding and similar such processes.
