Before that can happen, however, the ores must be excavated from the ground. Typically, this is done through two basic techniques: sub-surface (underground) and surface mining. Surface mining is both the less expensive of the two and the go-to method when the desired minerals are located near the surface of the Earth.

The basic extraction of metals from ores has the following steps. Grinding and Crushing The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation. Concentrating the Ore

Open-pit mining is the most common method used to extract iron ore. It involves using large machines to excavate large pits in the ground. The extracted iron ore is then transported to a processing plant where it is crushed and filtered to remove impurities. Strip mining Strip mining is another method used to mine iron ore.

Iron ore - Wikipedia. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite.

There are many methods for de-sludge and disintegration. The most common ways is washing, The mud with high mud content is usually washed by a cylinder washing machine or spiral washing machine. And the mud with low mud content is washed with trommel screen and then screening. 3, Gravity Separation The third process is the sorting process.

How is iron extracted and refined using carbon? Extracting iron Iron (III) oxide + carbon → iron + carbon dioxide. In the blast furnace it is so hot that carbon monoxide can be used in place of carbon to reduce the iron (III) oxide: iron (III) oxide + carbon monoxide → iron + carbon dioxide. Why is iron not extracted from its oxide by electrolysis?
