chapter . corrosion and oxidation material science and corrosion and oxidation .1 introduction. the unintentional deterioration of a material by an electrochemical process is known as corrosion. moreover, corrosion process is the reverse process of producing/extracting metal from ores, because pure metals tend to revert to their original state of oxides, sulphides and so on.is corrosion reverse of metal extraction? answersmar , · corrosion is a chemical reaction in which molecules break down due to a chemical reaction with its surroundings. most often, corrosion is the electrochemical oxidation of a metal (such as ironcorrosion (chapter 4) rust corrosion1. corrosion is a natural process. 2. corrosion is an electrochemical process. 3. corrosion leads to a tremendous loss. 4. corrosion is the reverse of metal extraction. causes of most metals exist in nature in combined forms that is in the corrosion form of ore. so extraction of metal from its ores is an unnatural process in which component ofproduced water treatment technologies internationalextraction of oil and gas leads to a reduction in reservoir pressure, and additional water is usually injected into the reservoir water layer to maintain hydraulic pressure and enhance oil recovery. iron <0.1 100 tss (mg/l) edta and other antiscaling chemicals are required for cleaning and process control. corrosion is prevented by phoverview of extraction of mineral/metals with the help oflakes, california. the livermore extraction process involves running a geothermal fluid through a reverseosmosis separation process to create freshwater and concentrated brine. the freshwater is used for evaporative cooling, and the concentrated brine is pumped into a reactor where chemicals are added and silica is extracted.why corrosion is reverse of extractive metallurgy? answersnov , 10· process of corrosion nd formation of oxide film is just reverse as in extractive metallurgyof metals.

Advantages of corrosion reverse process in extracion of iron

is corrosion a reverse of metallurgy? quoracorrosion is extractive metallurgy in reverse. for instance, iron is made from hematite by heating. iron corrodes and reverts to rust after completing its life cycle. the hematite and rust have the same composition; corrosion is the deterioration of materials as achemistry laboratory reports corrosionapr , 10· there is another definition that says that corrosion is the reverse of the process of extraction of metals from mineral ores. for instance, an iron ore minerals in the wild is in the form of a compound of iron oxide or iron sulfide, when extracted and processed, will produce steel used for making steel or steel alloys.corrosion behavior of epoxy (sigmaline) coated x65once existed in nature as stable ores, carbonates, or sulfides [1]. during metallurgical extraction process of ores, the refined metal absorbs a tremendous quantity of energy (unstable state), and corrosion is the natural means of releasing the high energy, thus reversing the metal to its initial low energy stable state [7].extraction of metals definition, factors occurencedec 06, · amalgamation and cyanide process of extraction are used for less reactive metals. common example is the silver. major steps in extraction extraction of metals from their natural sources is basicallya broad term which includes several steps in it. these steps start from exploraton of metal reservoirs to final refining of metals.effectiveness of electrochemical chloridechloride extraction (ece) technique on a bridge deck with very high concentrations of chloride. this ece technique was used during the summer of 03 to reverse the effects of corrosion, which had occurred in the reinforcing steel embedded in the pedestrian bridge deck over highway 6, along iowa avenue, in iowa city, iowa, usa.extraction unit sulfolane solvent regenerationthe solvent system employed in an acid gas sweetening process. any acid gas evolving from sulfolane decomposition or associated corrosion could be held in solution throughout at least part of the extraction unit interacting with degradation products and accelerating corrosion.corrosion process of ductile iron with cement mortaraffects the quality of the cml/iron interface, inducing the damage of the passive film and corrosion of the ductile iron. furthermore, the accumulation of corrosion products near the iron can also build up stresses and result in cracking of the cml, which in turn facilitates the ingress of corrosive agents and accelerates the corrosion of iron.metal corrosion and protection water treatment processany process of deterioration (or destruction) and consequent tom of a solid metallic material, through an unwanted (or unintentional) chemical or electrochemical attack by its environment starting at its surface is called corrosion, thus, corrosion is a process reverse of extraction of metals.
