Extraction of metals and the reactivity series. The most reactive metals are at the top of the series; The tendency to become oxidised is thus linked to how reactive a metal is and therefore its position on the reactivity series; Metals higher up are therefore less resistant to oxidation than the metals placed lower down which are more resistant to oxidation

Extraction of Metals from Ores – Different Processes Involved

The basic extraction of metals from ores has the following steps. 1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverization.
