Extraction of iron: reduction of metal oxides with carbon.

How do you extract metals from ores?

The carbon displaces the metal from the compound, and removes the oxygen from the oxide. This leaves the metal. The table summarises the extraction methods used for different metals. Subsequently, question is, how is electrolysis used to extract metals from their ores? Metals are found in ores combined with other elements .

extraction of metals - introduction

2021-9-9 · 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. Details for the extraction of aluminium, copper, iron and titanium are given in separate pages in this section.

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.
