Coal explained Mining and transportation of coal

Transporting coal. Coal can be transported from mines and processing plants to consumers in several different ways: Conveyors, trams, and trucks move coal around mines, for short distances from mines to that are consumers close to the mines, or to other modes of long-distance transportation. Trains transport nearly 70% of coal …

Making steel | ArcelorMittal

Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route. Both processes are being continually improved ...

How a Coke Plant Works

The properties of coke are influenced by moisture content and density. The main use of coke is to make iron. The burning of coal to coke produces carbon monoxide. A touch at the bottom of the furnace allows impurities to flow out of the furnace. This, coupled with the fact that many harmful impurities come from heating the coal is the reason ...

Coal Mining and Processing Methods

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called …

Raw materials

To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of 'stealing' the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c.

Use of coal

In 2022, about 513 million short tons (MMst) of coal were consumed in the United States. On an energy content basis, this was equal to about 9.8% of total U.S. energy consumption in 2022, or 9.85 quadrillion British thermal units, and the lowest percentage share since at least 1949. Although coal use was once common in the industrial ...

Types of Energy used in a Steel Plants and Energy Conservation

If available it can also be used as source of heat in various furnaces. By product fuels in the steel plant are namely (i) coke oven (CO) gas, (ii) blast furnace (BF) gas, (iii) converter gas, (iv) coal tar fuel, and finer fractions of coke (nut coke and coke breeze). Coke oven gas is a rich gas and has a calorific value ranging between 4000 to ...

How does coke and coal play into steel making?

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using …
