Introduction and Overview of Electrochemical Corrosion

Two processes are involved in the reaction, with each involving a change in charge: M to Mm+ and mH+ to m/2 H 2 (in acid solution). The changes in charge are accomplished by electron transfer from M to H+. Because the metallic phase is an electron conductor, it supports the electron transfer, allowing the two processes to occur at separate sites

Iron Ore Smelting Process

Mar 13, 2010The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the

Limestone features above ground

Limestone features above ground. Limestone scenery above ground (karst scenery) includes: Swallow hole. Surface water passes over an impermeable rock until it reaches permeable limestone. The water passes over the limestone and erodes vertical joints to form swallow holes. Over time the swallow hole increases in size as the result of erosion

Cement Manufacturing Process: What is Cement made of.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

What is geology

Seismologists: are geophysicists who study earthquakes, both to better understand the physical processes involved and to interpret the deep internal structure of the Earth.

Calcination of Limestone – IspatGuru

May 02, 2013Some limestone, due to its crystalline structure, disintegrates during the calcination process. This type of limestone is not useful for calcining. There is some other limestone whose behaviour is the opposite. This type of limestone become so dense during calcination that it prevents the escape of CO2 and become non porous.

Chemical Weathering

Oct 04, 2010Weathering refers to the process by which rocks are broken apart or chemically altered to become sediment. This process can be further subdivided into two categories: physical/mechanical weathering and chemical weathering.Chemical weathering refers to the processes by which rocks react with the atmosphere to form new substances.
