Malleability, Ductility, Minerals, Ores, Gangue, Calcination, Metallurgy, Concentration of chapter 3 can study by students of class 10. These definitiona and formulas of Class 10 Science Chapter 3: Metal and Non-metal is developed and witten by our expert teachers. Science formulas. Malleability, Ductility, Minerals, Ores, Gangue, Calcination, Metallurgy, Concentration of ores, Alloy, Amalgam, Aqua regia, Galvanisation is prepapred and collected from varius resources to help the students.
Malleability: It is the property of metals by which metals can be converted into thin sheets by using a hammer.
Ductility: It is the property of metals by which metals can be drawn into thin wires.
Minerals: The naturally occurring compounds of elements are known as minerals.
Ores: The mineral from which element can be extracted easily and profitably is called an ore.
Gangue: The impurities present in the ore such as sand, rocks etc are known as gangue.
Calcination: It is the process of heating concentrated ore in the absence of air below its meting point.
Metallurgy: It is the process in which pure metals are extracted from their ores.
Concentration of ores: It is the process in which the unwanted impurities (gangue) are removed from the ores.
Alloy: Alloy is the homogeneous mixture of two or more metals or metal and non-metal.
Amalgam: Those alloys in which one of the metals is mercury.
Aqua regia: Aqua regia is Latin word which means ‘Royal Water’. It is the mixture of concentrated Hydrochloric acid and concentrated nitric acid in the ratio of 3:1. It is capable of dissolving metals like Gold and Platinum.
Galvanisation: It is a method by which iron and steel can be prevented from rusting. In this method a thin layer of Zinc is made on the article which prevents them from rusting.
