Cleveland-Cliffs new 100 million plant on the Iron Range will be the first in the country to use an improved technology that produces a special type of higher-quality iron-ore pellet.
The Silver Bay Minn. plant part of Cliffs Northshore Mining operation will begin producing direct reduced iron DRI pellets when the plant opens in August. The pellets are a special type of low-silica iron-ore pellet that are more valuable than the traditional taconite or blast-furnace iron pellets now produced in the U.S. the company said Friday.
Cliffs upgrade is important state officials said noting that DRI pellets can be used in the more desirable electric arc or minimill furnaces that convert iron into steel. The traditional taconite iron pellets now made across Minnesotas Iron Range can only be used in old-fashioned blast furnaces not in the efficient minimills.
Yet electric arc furnaces are growing in popularity. The state of Minnesota estimates that about 67 of the worlds steel is now made by feeding scrap steel and DRI into electric arc furnaces. So the DRI pellets are badly needed in the United States. Right now they are largely imported into the U.S. said officials with the Iron Range Resources and Rehabilitation Board.
Cliffs expansion efforts in Silver Bay are the latest of several growth actions in recent years following a major restructuring that had the once-ailing Cliffs selling off coal plants and other assets worldwide. Besides Northshore Mining Cliffs also operates Hibbing Taconite and United Taconite on the Iron Range.
To expand into DRI production in Silver Bay the Ohio-based Cliffs upgraded its concentrator building built a new scavenger building and invested in new conveyor systems a limestone tank and a steam-generating plant. All will support the large-scale commercial production of the DR-grade pellets the company said.
The DRI pellets will be sent to Cliffs 830 million hot-briquetted iron plant in Toledo which is still being completed and a new unnamed customer outside the United States the company said.
In 2017 Cliffs expanded operations at United Taconite in Forbes Minn. by building a 75 million Mustang superflux pellet plant.
Get uniform pellets with excellent metallurgical and physical properties. Outotec39s traveling grate pelletizing plant is the industry39s leading induration technology for iron ore pellet production for a wide range of plant capacities. Based on over 60 years39 experience and world-class RampD our process produces uniform pellets and ensures high performance and quality with low investment and operating costs as well as decreased energy consumption and emissions.
Outotecs traveling grate pelletizing process consists of a green balling section where after the mixing stage green pellets are formed either by rolling on discs or in drums. The green pellets are then screened and heat-hardened in the indurating furnace.
During induration the green pellets are distributed evenly across the traveling grate and then hardened in a furnace where they pass through updraft drying downdraft drying preheating firing afterfiring and cooling zones. Our unique updraft and downdraft drying sequence significantly reduces fuel consumption. The homogeneous pellet charge on the grate reduces the pressure drop within the furnace which further reduces energy consumption and enables an even heat treatment resulting in high-quality pellets.
Economical and environmentally friendly gas flow and gas cleaning systemA range of recuperation techniques are appleid to the grates gas flow in order to reduce both fuel consumption and atmospheric emissions
Sep 12 2018nbsp018332Iron ore pellets. Pellets are small and hardened iron balls with a diameter of 10-20 mm and are used as raw material for ironsteel manufacturing. The pelletizing process was commercially introduced in the world market in 1955 following the World War II scarcity of high-grade natural iron ore in the United States.
A traveling grate pelletizing plant typically comprises the following equipment

Pellets are small and hardened iron balls with a diameter of 10-20 mm and are used as raw material for ironsteel manufacturing. The pelletizing process was commercially introduced in the world market in 1955 following the World War II scarcity of high-grade natural iron ore in the United States. Hence the need to utilise low-grade ore was paramount and this commenced the process of sintering and palletization. Moreover palletization is a process designed to transform iron ore fines into agglomerates to feed Blast Furnace BF and Direct Reduced Iron DRI producing units.
Benefits of using pellets pellets are a better feed for iron making as compared to other feeds due to its various benefits which includes uniform size high metallization rate increased permeability in blast furnaces to optimise fuel consumption rate among others.
The ex-China share of BOF steel declined from 63.1 to 55.3 due to the strong growth in EAF steel production. The rising share of EAF steelmaking route was led by consumption of pellets as well as the availability of steel scrap in the developed countries which increased the overall share of EAF. The global ex-China EAF share of steelmaking increased gradually from less than 37 2000 to 46 2017 whereas Chinas share of EAF steelmaking declined from 16 to 9 over the same period although it increased in volume.
Mar 21 2015nbsp018332Iron ore pellets can be made from beneficiated or run of mine iron ore fines. Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making process.
KOBELCO-Pelletizing Process can produce superior and various quality pellets because of application of rotary kiln where pellets are heated and fired unifomly know-how of plant operation amp quality control and advanced process control system. And the process can use various iron ores such as magnetite ore hematite ore dry or wet material.
When pellets are fed onto the grate they are dried and then pre-heated up to a temperature of about 800-900 deg C. The heat used to dry and preheat the pellets is typically hot air pulled from the indurating section and cooling zone. The recycling of the the hot air
