Extracting Metals with Carbon. The Earth's crust contains metals and metal compounds such as gold, copper, iron oxide and aluminium oxide. Useful metals are often chemically combined with other substances forming ores. A metal ore is a rock that contains enough of the metal to make it worthwhile extracting. Common examples of oxide ores are …

3. What is Production? Production means, a process by which resources (men,material, time etc.) are transformed into a more useful commodity or services. In general, Production means transforming inputs ( Labour, machines, raw materials, etc.) into an useful & desired output. For e.g. Steel from iron ore, Legal services like medical, consultancy, …

Metals & Non-metals Metallic and Non-Metallic Character of the Elements. The elements can be divided into two broad types: metals and non-metals Atoms of different elements which do not have a full outer shell of electrons, can try to achieve a full outer shell by gaining or losing electrons in chemical reactions - this leads to the formation of ions

Metal Reactivity The Reactivity Series. Based on how they react with other substances, a reactivity series can be produced in which the metals are placed in order of their reactivity Metal atoms form positive ions by loss of electrons when they react with other substances The tendency of a metal to lose electrons is a measure of how reactive the metal is

The reactivity between two metals can be compared using displacement reactions in salt solutions of one of the metals. This is easily seen as the more reactive metal slowly disappears from the solution, displacing the less reactive metal. For example, magnesium is a reactive metal and can displace copper from a copper sulfate solution:

Metals consist of giant structures; Within the metal lattice, the atoms lose their outer electrons and become positively charged metal ions. The outer electrons no longer belong to any specific metal atom and are said to be delocalised; Metals can conduct electricity because the delocalised electrons are able to move through the structure and carry a charge

Extracting metals Choosing methods for metal extraction. The position of the metal on the reactivity series determines the method of extraction. Higher placed metals (above carbon) have to be extracted using electrolysis as they are too reactive and cannot be reduced by carbon. Lower placed metals can be extracted by heating with carbon which ...
