In this section, we are going to talk about the extraction of metals. Here, we'll see the methods used in the extraction of certain metals like Iron, copper, Aluminum, etc Below are quizzes to facilitate your understanding of the concept. Before moving to that, let's have a recap of what the topic is all about:

An ore is a mineral containing enough metal that makes the metal worthy of extraction. Carbon could be used in the extraction of metals from some metal oxides, with the metal being capable of either being reduced or oxidized in the reaction. 

There are 3 main methodologies of extracting metals from their respective ores. They include the reduction of the ore with carbon, the reduction of the molten ore by electrolysis, and the reduction of the ore with a metal that is more reactive. 

Ores that are recovered by mining include metals, coal, limestone, etc Mining is needed to obtain any material that cannot be grown through any agricultural process nor created in a laboratory or factory. In a wider sense, mining includes the extraction of any non-renewable resource. Mining usually leaves behind a negative impact on the environment, hence some countries have restricted that in order to reduce the impact on the environment. This is necessary.

During the exams, students are expected to be able to describe the various ways of extraction of the given metals. They are expected to master the concept well so as to get a good pass in questions asked on this topic. For more entertaining quizzes, click here.
