A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap between the mantle line movable mounted on the
2.2 Basics of iron and steel production Secondary, or scrap based, production of steel is very straightforward. Melting steel scrap all primary iron and steel production processes are based on the same chemical reactions. In iron ore, iron is presents in its oxidised form. In iron reduction processes, a reducing agent, based on carbon or hydrogen, removes the oxygen from the
production of secondary steel using scrap see Figure 2 due to the chemical energy required to reduce iron ore to iron using carbon based reducing agents. Because reduction does not take place at room temperature, reducing agents such as coal, coke and natural gas also supply energy for the heat needed. Coke, made by carburising the coal i.e. heating in the absence of oxygen at high
Primary production is the process through which new aluminum is made versus secondary production, in which existing aluminum is recycled into pure metal. Aluminum originates from bauxite, an ore typically found in the topsoil of various tropical and subtropical regions. Once mined, aluminum within the bauxite ore is chemically extracted into alumina, an aluminum

Iron ore is converted into various types of iron through several processes. Themon process is the use of a blast furnace to produce pig iron which is about 92 94 iron and 3 5 carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mininges prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
Horizontal shaft impact HSI crushers are used in primary, secondary or tertiary crushing stage. HSI crushers reduce the feed material by highly intensive impacts originating in the quick rotational movement of hammers or bars fixed to the rotor. The particles produced are then further fragmentated inside the crusher as they collide against crusher chamber and each other,

Coke is mainly used to make iron, which, in turn, is used as the main ingredient in steel. The World Coal Association outlines the iron making process roughly as follows. During a typical iron making procedure, iron ore, coke and small quantities of minerals used to collect impurities are placed into a blast furnace. Superheated air is then blown into the furnace, making the coke

A trainload of iron ore at a Canadian National station in Eastern Canada en route from an emergency war mining project to the steel mills at Sydney, Cape Breton, Nova Scotia, where it is made into plates for ships, rails, billets for guns, tanks, shells, bombs and other war weapons. These cars have a capacity of sixty five tons but due to the weight of the ore a full load only fills half a car.

Cast iron begins its life as pig iron, which is remelted andbined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this process up. Molds can be made as expendable molds
It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also describe plants where steel semi finished casting products are made from molten pig iron or from scrap. History. Since the invention of the Bessemer process, steel mills have replaced ironworks, based on puddling or fining methods. New ways to produce steel appeared

A secondary concentration of nine furnaces was found in the Mahoning Valley. The iron industry had slowly switched its fuel source from charcoal to coke, a purified form of bituminous coal. The burning coke, when exposed to blasts of air hence the name blast furnace, creates the high temperatures needed to melt iron ore for processing into ingots. These ingots originally were named

Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.
