· What element is used to extract metals from ores? Carbon An ore is a mineral that contains enough metal to make it worth extracting the metal. Carbon can be used to extract metals from some metal oxides. A metal can either be reduced or oxidised in a reaction. Reduction occurs when a metal in a compound loses oxygen, to form the elemental metal.
· 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 ...
Q. A method of extracting metals from their ores that are more reactive than carbon. answer choices. carbon extraction. fractional distillation. electrolysis. cracking. Tags: Question 14.
Extracting the required metal using a suitable process: After choosing a suitable process based on the reactivity of the required metal several precautions need to be taken since many ores do not contain just one metal hence a suitable process in which the metals can be separated needs to be used. For example, extracting magnesium from dolomite ...

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.
