18.2. General Principles of Extraction of Metals The process of extracting the metals from their ores and refining them is calledmetallurgy. The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore.

Extracting a metal from its ore chymist

Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure state.

Extraction Of Metals Definition, Factors Occurence

Dec 06, 2019· As the figure indicates, the method of extracting some metal depends on physical and chemical nature of that metal. Metals which are present on highest position in the reactive series are difficult to extract and thus they are extracted by electrolysis. While others which are lower in the series are easier to extract.

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. 2. Concentration (Dressing) of ores. The technique of removing gangue, the rocky impurities like Sio 2

Extracting a metal from its ore chymist

Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction.
