Activities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram. Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine. Excellence in planning, scheduling and quality control are fundamental to the process.
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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)#183;n(H 2 O), 55% Fe) or siderite (FeCO

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
Exploration is the process by which the accumulations of iron ore minerals can be found in the earths crust. Before the heavy investments required to set up a mining operation is done, the mining organization is to ensure that the deposit is economically viable and it has quantities of ore that will ensure ore production over a sufficiently long period of time.
Iron ore is an important raw material for iron and steel production enterprises. After crushing, grinding, magnetic separation, gravity concentration etc, gradually we can get iron from natural minerals (iron ore). It is the mineral aggregates that contain iron or iron compounds which can be used economically. Production Process of Iron Ore

Mining automation, process control amp; optimization Increasing the level of mine automation and integration Automation is not new to mining, but it is generally more basic in mines than in other industries and is often limited to simple control of motors, equipment or certain parts of processes.
This saves mining operations multiple millions in USD every month since iron ore beneficiation increases significantly the costs per ton of ore. Control of the moisture content on the mining conveyor belt (NIR) together with accurate monitoring of the composition of iron ore before shipment guaranties constant ore quality to avoids penalties.
Iron Mining Process. From blasting to crushing to separation more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nations steel. Blasting Taconite is a very hard rock. The iron ore is separated from the taconite using magnetism.
FROM IRON ORE TO IRON SINTER PROCESS CONTROL USING XRAY DIFFRACTION (XRD)* Uwe K#246;nig1 Nicholas Norberg2 Luciano Gobbo3 Abstract Traditionally quality control of iron ore sinter, its raw materials and raw mixtures has relied on timeconsuming wet chemistry. The mineralogical composition that defines the properties is often not monitored.
#0183;#32;Iron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
When the iron ore is extracted from the 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 crushers CSS before the crushing stage. A static screen is used to divert...
