By means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel companies. the iron ore produced by vale can be found in houses, cars and household appliances.
mining is being increasingly carried out underground as open pits near the end of their mining life and new ore bodies are increasingly being identified deep underground. constructing underground mines with the use of conventional shaft and tunnel boring machines, however, has proved to be technically challenging, expensive and sluggish.underground mining. underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. the entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline. underground mining is practical when:
open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. this surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth.northern iron, which operated a mine in kirkenes in norway, had to file for bankruptcy in 2015. northland resources in sweden also went bankrupt. the state-owned swedish mining company aktiebolag is the largest manufacturer in europe, accounting for over of the produced iron ore the company mined
the basics of copper mining and processing. mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. using todays compact mining equipment, copper ore is extracted from the mine. after the ore is crushed, its roasted, which helps to convert sulfides to oxides.about 98% of world iron ore production is used to make iron in the form of steel. iron in cast form has many specific uses but pure iron is quite soft. adding a small amount of carbon makes iron into steel which is

manganese removes oxygen and sulfur when iron ore is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. the amount of manganese used per ton of steel is rather small, ranging from to kilograms.economic minerals gold gold mining and exploration in zimbabwe has been going on from ancient times and it is estimated that a third of all historical gold production was mined locally from the seventh century until the introduction of mechanized mining methods with the arrival of europeans about a century ago.
iron ore is then transported and shipped to milling plants. this guide provides information on standards, certification schemes and other industry specific information that may be of interest to anyone working within the iron ore mining industry, including information relevant to miningIn recent years, a number of mining companies have turned to continuous mining systems. this include fmg in the pilbara, where continuous mining machines having rotating drums fitted with picks are used to mine iron ore, and bma and rio tinto in the bowen basin where in-pit-crusher conveyors are used to transport overburden.
the world will need iron ore for as long as the world needs steel.
