method of separation of ore?
Answers
The method of magnetic separation is the process of separating ore from the gangue particles based on the magnetic properties of either ore or matrix. In this method, the ore is finely crushed and then passed over the magnetic roller, where one is magnetic, and the other is nonmagnetic.
Answer:
To obtain a metal from its ore is called extraction of metal. The various processes involved in the extraction of metals from their ores, and refining are known as metallurgy.
1. Concentration of ore (or Enrichment of ore) ,
2. Conversion of concentrated ore into metal, and
3. Refining (purification) of impure metal.
Explanation:
1. Concentration of ore
The methods used for removing gangue from ore depend on some difference in the physical properties or chemical properties of the ore or gangue.
2. Conversion of concentrated ore into metal
The extraction of a metal from its cocentrated ore is essentially a process of reduction of the metal compound present in the ore. The method of reduction to be used depends on the reactivity of the metal to be extracted.
3. Refining of metals
The process of purifying impure metals is known as refining of metals.
The method to be used for refining of metals depends on the nature of metal as well as on the nature of impurities present in it.
The most important and most widely used method for refining impure metals is electrolytic refining.
Electrolytic refining means refining by electrolysis.
