Jul 28 2012 · There are different steps involved in extraction of metals Let us discuss them one by one 1 Crushing and Grinding First of all ores are crushed into a fine powder in big jaw crushers and ball mills This method is called pulverization is called concentration of an ore or ore dressing and the purified ore is called
The extraction and isolation of metals from ores involve the following major steps: Concentration of the ore, Isolation of the metal from its concentrated ore, and Purification of the metal. The entire scientific and technological process used for isolation of the metal from its ores is known as metallurgy. 6
The basic extraction of metals from ores has the following steps. Grinding and Crushing The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation. Concentrating the Ore
Solution. The correct option is D All of the above. The extraction of a metal from its ore involves mainly three stages. They are: I) Concentration or Dressing. II) Extraction of crude metal. III) Refining or purification of the metal. Chemistry. Suggest Corrections.
The following are the various steps in the metal extraction or metallurgical process: Crushing and grinding the ore. The concentration of ore, is also known as ore enrichment. Metal extraction from concentrated ore. Impure metals are refined or purified. Copper Flash Smelting Process. Principles of Metallurgy:
Extraction of Crude Metal. The extraction of crude metals from the concentrated ores is carried out in two steps namely. Conversion of the ore into oxides of the metal of interest and; Reduction of the metal oxides to elemental metals. In the concentrated ore, the metal exists in positive oxidation state and hence it is to be reduced to its elemental state.
