physical and chemical processes to extract a metal from an ore

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

extraction of metals - introduction

Some copper ores can be converted into copper (II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper (II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.

Extraction of Metals Good Science

The form in which a metal exists in an ore depends on its chemical reactivity. The least reactive metals, such as gold, silver and copper, usually exist as native metals. They only need to undergo physical separation processes to be extracted. More reactive metals, such as iron and aluminium, exist as minerals. They need to undergo chemical ...

What is Concentration of Ore? Definition, Physical ...

The ore concentration is defined as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals. In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. The ore can be concentrated or separated by both
