Extraction of Metals
Extraction of Metals - Once the ore is calcined or roasted, the process of reduction obtains the metal. The extraction of metal from the calcined or roasted ore consists of two steps viz., Removal of the Earthly impurities. Reduction of th..
Principles and Processes of Extraction of Metals
There are 109 elements known at present. 92 elements occur in nature, while the rest are man-made. All materials on the Earth are made of these naturally occurring elements. These are classified into metals, non-metals, and metalloids. The occurrence and extraction..
Extraction of Metals - Metallurgy
The compounds of various metals found in nature as ores are mixed with impurities like sand and rock. The various processes involved in the extraction of metals from their ores and their subsequent refining are known as metallurgy. An overview of v..

Alloys
An alloy is a mixture of two or more metals fused together in molten state. Metals when melted tend to dissolve in one another forming alloys. The various properties of a metal like malleability, ductility, strength, hardness, resistance to corrosio..

Extracting Metals in the Middle of the Activity Series
Extracting Metals in the Middle of the Activity Series - Metals such as iron, zinc, lead, copper, etc., are in the middle of the reactivity series. These are moderately reactive metals and are usually present as sulphides or carbonates. A metal is o..
Extracting Metals Low in the Activity Series
Extracting Metals Low in the Activity Series - Metals that are low in the activity series are very un-reactive. The oxides of these metals can be reduced to metals by heating alone. For example, mercury is obtained from its ore, cinnabar (HgS), by t..

The process of electrorefining of metals involves the following steps: The electrolyte is usually an aqueous solution of the salt of the metal with some corresponding acid, if necessary. A thick block of impure metal is made the anode. A th..

They always come through for me never fails me,great tutors,cant say thank u enough,lets hope we score big on the exams :-) - Jenna
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
Tutor was great help. An excellent tutor. If she is not already a platinum tutor, she deserves to be. Very thorough.
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
