JEE (Main+Advance) e-advance Course Isolation of Metals

Isolation of metals is an important topic in chemistry and is a part of the JEE (Main+Advance) e-advance course. The process of isolating metals involves the extraction of a metal from its ore and its purification.

The following are the important methods used for the isolation of metals:

1. Froth Floatation: This method is used for the concentration of sulphide ores. The ore is powdered and mixed with water and some collectors (such as pine oil) and frothers (such as sodium ethyl xanthate) are added. Air is then blown into the mixture, causing the mineral particles to rise to the surface and form a froth. The froth is then skimmed off and the concentrated ore is obtained.
2. Roasting: This method is used for the extraction of metals from their sulphide ores. The ore is heated in the presence of air to convert the sulphide into oxide. For example, the sulphide ore of zinc is roasted to give zinc oxide and sulphur dioxide gas.
3. Smelting: This method is used for the extraction of metals from their oxide ores. The ore is mixed with a reducing agent (such as coke) and heated in a furnace. The metal oxide is reduced to the metal, which is then collected at the bottom of the furnace. For example, iron oxide is reduced to iron by heating it with coke in a blast furnace.
4. Electrolytic refining: This method is used for the purification of metals. The impure metal is made the anode and a strip of pure metal is made the cathode. The metal is dissolved in a suitable electrolyte and a current is passed through it. The impurities settle down at the bottom of the anode and the pure metal is deposited on the cathode.

These are some of the important methods used for the isolation of metals. It is important to understand these methods thoroughly to excel in the JEE (Main+Advance) e-advance course.
