Metals that require the least amount of energy to extract, those that occur in nature as the element (native metals) were the first metals used by humans in ancient times. Metals that require a moderate amount of energy to extract, that is, those that can be extracted by heating their ores, were the next to be used widely.

The process of extracting a metal in pure form from its ore is known as metallurgy. The process of treatment depends on upon the nature of the ore, impurities, and the metal. From the extraction point of view, the metals can be broadly classified into five categories.

SYLLABUS POINTS: o Define the terms mineral and ore with reference to economic and non-economic deposits of natural resources. o Discuss the importance of predicting yield in the identification, mining and extraction of commercial ore deposits. o Explain why ores are non-renewable resources.

4.7 Explain why the method used to extract a metal from its ore is related to its position in the reactivity series and the cost of the extraction process

The process of separating metals from their ores is called extraction. Based on the composition of the deposit, the price of extracting the metal changes, so the value of extracting the metal must be weighed against the cost.

Bioleaching is the extraction of metals from their ores through ... Many people know that extracting metal ores from the ground damages the ground, ...

Carbon is a non-metal but it is more reactive than some metals. This means that some metals can be extracted. from their metal oxides using carbon. Less reactive metals than carbon can be extracted from their oxides by heating with carbon. In general: metal oxide + carbon → metal + carbon dioxide. This works for zinc, iron, tin, lead and copper.

Generally questions from the topic Elements and their Ores are asked in every competitive exam. So, here are short notes on Some Important Ores of Metals …

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore.

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.

Metal ores are generally oxides, sulfides, silicates, or native metals (such as native copper) that are not commonly concentrated in the Earth's crust, or noble metals (not usually forming compounds) such as gold. The ores must be processed to extract the elements of interest from the waste rock and from the ore minerals.

Metallurgy, art and science of extracting metals from their ores and modifying the metals for use. Metallurgy customarily refers to commercial as opposed to laboratory methods. It also concerns the chemical, physical, and atomic properties and structures of metals and the principles whereby metals are combined to form alloys.

Metals can be categorized into three parts on the basis of their reactivity: most reactive, medium reactive and least reactive. Steps of Extraction of Metals Concentration of ores: Removal of impurities, such as soil, sand, stone, silicates, etc. from mined ore is known as Concentration of Ores.

A metal ore is a rock containing a metal, or a metal compound, in a high enough concentration to make it economic to extract the metal. The method used to extract metals from the ore in which they are found depends on their reactivity.

Very few metals such as the noble metals, i.e., Gold, Silver, and Platinum etc. are present in their original metallic forms in nature. Metallurgy is the field of science which deals with the extraction of metals from ores which are naturally found in the environment.

Metal extraction from ores occurs in many different ways involving physical, chemical and electrical means. Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its …
