Chapter 18, Problem 57QAP

Interpretation Introduction

Interpretation:

The process of returning metal t their natural state-the ore should be determined. If the metal undergo reduction or oxidation should be determined.

Concept Introduction:

The minerals containing metals are known as ores. There are different methods involved in the extraction of different types of ores. There are some common metals like iron which are smelted in the presence of carbon atoms as a reducing agent. Some of the metals such as aluminium and sodium do not have compatible reducing agent this they are extracted by the process of electrolysis. Directly metal cannot be obtained from the sulphide ores. They are reduced by the process of roasting which takes place in the presence of air and results in the formation of oxides.
