World high carbon ferrochrome production, charge chrome and HCFeCr, was million tonnes in 2005. The production increased by per cent from the year 2004. Almost all ferrochrome is produced in submerged electric arc furnaces. The raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral.
The production process starts when 10 000 kg/h of liquid ethylbenzene stream is preheated from ambient temperature (25 °C) to a temperature of about 136 °C using a shell and tube heat exchanger.
of iron and steel produ cts; the recy cling of scrap; and the losses of iron and steel during the steelmaking and produ ct fabriion processes during 1998. The flow diagram shows the quantities of iron present at stages of steel product manufacture, shipping, and recycling.
Transferrin iron complex is the transport form of iron of the plasma and is carried to the myeloid tissue, liver, spleen, lymph node and other tissues of the body. Transferrin is thus the iron binding protein of the plasma and it shuttles iron atoms between .
There are two main processes for producing steel: by means of a blast furnace (= indirect reduction) in combination with a converter, or by means of an electric furnace. In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron.
The flow chart also helps in identifying each unit operation in the process which helps in proper selection of equipment and better management of man and machines. For example, the type of equipment that will be required for the preparation of dehydrated vegetables will be as follows. 2 Dairy and Food Engineering Prof. S K Dash
Figure61 shows flowsheets for pyrometallurgical' and hydrometallurgical2 copper production. Tables 61 and 62 provide capsule summaries of these processes. 1 PyrometaIIurgy IS the extractIon of metaI from ores anD concen trates using chemical reactions at high temperatures.
· In the blast furnace, the iron ore reacts with the carbon contained in the coke to form grey or white pig iron. 1 Combustion process 2 Boudouard reaction 3 Preheating 4 Indirect reduction zone 5 Direct reduction zone 6 Carburizing zone 7 Melting zone 8 Tapping zone Combustion process
· The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found .

Flow diagram of production process, since 1870s Lay out of production process with flow signs, since 1940s Process flow diagrams A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indie the general flow of plant processes and equipment. See Category:Process flow diagrams
specifically, the head office plans the following schedules: (1) ship chartering schedules to secure ships to transport raw materials con sidering the tapping quantity (outputs of pig iron) and outputs of coke at the entire company, (2) ship loadschedules to determine which ships are assigned to which loading place (mine and coal mine) .
Ferroalloy Production General Ferroalloy is an alloy of iron with some element other than carbon. Ferroalloy is used to physically introduce or "carry" that element into molten metal, usually during steel manufacture. In practice, the term ferroalloy is used to include any alloys that introduce reactive elements or alloy

Figure 1: Overview of copper production Benefiion process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine ( – 1 %
· The process. The process discussed here comprises two main phases: first, acrylonitrile is polymerized with methyl acrylate comonomer and additives in an aqueous solution of demineralized water; then the copolymer is passed through transformation steps to become a fiber.
