Iron Ore Mining Process Explained. Necessary for the initial stages of the mining process, a miner's tools were generally constructed of iron with wooden handles and included a shovel, pike, hoe, pick, hammer and wedge. The ore reaped by these tools then needed to be hauled to the surface through a variety of means. Get Price.

Iron removal by physical-chemical way consists in iron oxidation by air followed by sand filtration, but other techniques exist as well: Oxidation can be carried out by various chemicals like chlorine, ozone but is mostly done by compressed air. Complex bound iron and manganese, e.g. complex bound with humic acids, can be very difficult to remove.

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.

The combustion processes which have attempted to produce a product which might be classified as a pig steel rather than pig iron, have failed largely for economic reasons rather than because of metallurgical difficulties. They were not adapted to the large units necessary to turn out a large tonnage, as is the case in the manufacture of pig iron.

The reduction of iron oxides takes place according to the following chemical equations: (1) F e 2 O 3 + 3 C O → 2 F e + 3 C O 2 (2) F e 2 O 3 + 3 H 2 → 2 F e + 3 H 2 O In contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to 1000 °C. The iron ores are therefore not melted!
