In metal extraction, a vast majority of metallurgical reactions are made to take place at elevated temperatures because than the ore compounds become relatively unstable, facilitating the release of the metal. This is the basis of pyrometallurgy. Pyrometallurgy deals with the methods of extraction of metals from their ores and their refining and is based on physical and chemical changes occurring at high temperatures, i.e. 500-2000°C.
Reaction rates are greatly accelerated at high temperatures. So small units can achieve high production rates.
Some reactions which are not thermodynamically possible at low temperature become possible at high temperatures.
At high temperatures the products get melted or vaporized which makes easy, the physical separation of product metal from the gangue.Ex. Meta-Slag separation.
Pyrometallurgy can bring about the reduction of a compound, which cannot take place in presence of water i.e. it has got ability to extract the reactive metals which can't be reduced from aqueous solutions. Ex. Alkaline earth metals, zirconium, titanium etc.
We will be updating general study materials which will surely help you in your studies.
I just wanna be updated of any any new materials to help me in my course.
Hi, good evening. I'm student of metallurgy. Can anyone tell me good books to prepare for gate.
Besides the normal course books, you can refer to GATE 2013: Metallurgical Engineering by G.K. Publishers. I would also advice you to go through previous years GATE papers and study the pattern of questions from different sections of metallurgy.
Hi, good evening. I'm a student of metallurgy. Can anyone tell me books for corrosion and powder metallurgy?
corrosion concept follow this books ……….fontana and zaaki ahmed…………my self follow its……….
Hi Babu, you are from which university?
Hi…i am doing my last year B.tech in metallurgy,i am fully interested to do my MS in Germany, can you please tell me whether my idea is perfect if so tell me how to apply for the top most universities in Germany.
hi nitya U R from which university………..
hi, good evening. I'm from nit jamshedpur, my branch is metallurgical and materials engineering.i want to go in the field of research.which book i shud follow…???
Appreciable decision, but tell me your area of interest then only we can suggest any books that enhance your passion.
Can u please tell me whether my idea is gud ? ? ?
Can u tell me about careerjobs in metallurgy?????
f ) Government organization include ISRO, DRDO, DMRL and Railway.
The material science component of this course is frontier area of research in the west.
It includes the study of semiconductor and nanotech.
Can u suggest project work Ideas for metaalurgy?????????
hi ..i am satya sri,i am studying engg-2nd year….(meterial and metallurgy engg),i want to prepare some interesting books for mechanical metallurgy and non-ferrous extractive metallurgy….please tell me good books…..
Now a days most metals are being extracted by pyrometallurgical process.
Hi…i am doing my last year B.eng. in metallurgy,a nigerian i am fully interested to do my MS in Germany, can you please tell me whether my idea is perfect if so tell me how to apply for the top most universities in Germany.
