Extraction of Moderately and Less Reactive Metals
28 nov. 2021The less reactive metals, which are near the bottom of the reactivity scale, are removed solely by reducing their oxides with heat. Mercury and copper, for example, are less reactive metals that are near the bottom of the reactivity series. As a result, we’ll look at how to extract mercury and copper by reducing their oxides with heat alone.

Extraction of Metals: Ores, Definition, Examples – Embibe
25 janv. 2023Metals like copper and silver occur in a free state and the combined state in the Earth’s crust. Metals lying in the middle of the reactivity series like zinc, iron, lead, etc., are moderately reactive and occur in a combined state. These elements occur mainly as oxides, sulphides, or carbonates.

The less reactive metals are extracted by the reduction of their oxides by heat alone. Example: Mercury (II) sulphide ore is roasted in air when mercury (II) oxide is formed. When this mercury (II) oxide is heated to about 300oC, it decomposes to form mercury metal. Advertisement Answer 4 people found it helpful varadad25
