FORM 6 CHEMISTRY STUDY NOTES-EXTRACTION OF METALS

This method is used in extracting metals which are strongly electropositive (more reactive) like Na, K, Ca, Mg and Al. These metals cannot be reduced by the normal reducing agent like Co or Carbon because their compound (ores) is stable. Even if the metal is formed, carbon reacts with the metal produced to form carbide at high temperature. These reactive metals are extracted by passing through their molten or fused chlorides oxides

Extraction of Metals CIE IGCSE Chemistry Revision Notes

Carbon burns in a blast of very hot air to form carbon dioxide: C + O 2 → CO 2. The carbon dioxide produced reacts with more coke to form carbon monoxide: CO 2 + C → 2CO. The carbon monoxide is the reducing agent and reduces the zinc oxide to zinc: ZnO(s) + CO(g) →Zn(g) + CO 2 (g) Note that the zinc produced is in the gaseous state

Metal Extraction Reduction AQA GCSE Chemistry

Metals higher up are therefore less resistant to oxidation than the metals placed lower down which are more resistant to oxidation. 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.

IGCSE Extraction of Metals From Ores Notes - IGCSE And

Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides. Some other mineral or other compound is also present. But the majority is a metal
