The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore. The high purity limestone is crushed in a lone in jaw crusher and then crushed more in a secondary crusher to reduce the size to completely pass through a 50mm sieve. Then, it is stacked by a limestone

8/07/2008· Sipsey Mine Workers, 1913 Birmingham owes its 1871 founding to the geological uniqueness of the Jones Valley, the only place on Earth where large deposits of the three raw materials needed to make iron—coal (for conversion into coke), iron ore, and limestone—existed close together. Named for the industrial heart of Great Britain, the city prospered and grew as the iron, coal, and steel

Alabama's coal and iron industries were devastated in the spring of 1865, however, during a series of cavalry raids by Union forces under General James H. Wilson. Despite numerous attempts to rebuild the state's industries, coal mines remained relatively dormant until the mid-1870s, when Alabama's economy began to recover.

Coke Ovens & By Products Plants. There are three basic ingredients to make iron and iron, in turn, is used to make steel. The three basic ingredients are iron ore, limestone, and coke. The first two are natural raw materials, but coke is a by product of coal, when coal is heated under controlled circumstances. This heating occurs in a "coke oven".

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more

4/04/2012· Specifically, (a) direct use of iron oxide concentrates without the need for pelletization or sintering; (b) no cokemaking required (if coal is used to generate the hot reducing gas, pulverized coal of wide variety can be used); (c) high temperature can be used because there will be no particle sticking or fusion problems; (d) possibility to produce either solid or molten iron; and (e) low

13/11/2017· The iron-rich powder is mixed with clay and made into marble-sized pellets, which are then heat-hardened. That allows for more efficient burning during the next step, smelting. Smelting: The pellets are smelted in a furnace along with coke—coal that has been processed into almost pure carbon—and limestone.

The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

Shale Uses. Shale has many commercial uses. It is a source material in the ceramics industry to make brick, tile, and pottery. Shale used to make pottery and building materials requires little processing besides crushing and mixing with water. Shale is crushed and heated with limestone to make cement for the construction industry.
