- When a metallic compound is melted or dissolved, the ions are free to move about within the liquid or solution. Passing a current through substances that are molten or solution means that the solution can be broken down into elements. This is electrolysis, and the substance being broken down is the electrolyte.

Jun 30, 2023 · This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis.
The most reactive metals will react with cold water: Products are a metal hydroxide (forming an alkaline solution) and hydrogen gas. E.g. with potassium: 2K + 2H2O -> 2KOH + H2. Fairly reactive metals react with acids: acid + metal → salt + hydrogen.

Dec 11, 2019 · At 11–14, students need to understand how metals are extracted, what an ore is, and reduction and oxidation. These worksheets help to build this knowledge, taking the extraction of iron, lead and copper as examples.
Metals are extracted from ores which are rocks found on the Earth’s crust which contain metal compounds. Different methods can be used to extract the pure metal from ores. The method used depends on the metal’s position in the reactivity series.
