NEET Chemistry General Principles and Processes of Isolation of Elements

General Principles and Processes of Isolation of Elements is an important chapter in Inorganic Chemistry that deals with the extraction and purification of metals from their naturally occurring ores. The study of these processes is known as metallurgy.

This chapter is highly important for NEET Chemistry and frequently appears in conceptual questions.

What is Metallurgy?

Metallurgy is the science of extracting metals from their ores and refining them into pure forms suitable for industrial and commercial use.

Important Concepts

Occurrence of Metals

Most metals occur in nature as compounds known as ores. These ores are the primary sources for obtaining metals.

Concentration of Ores

The unwanted impurities present in ores, called gangue, are removed through concentration processes before extraction.

Extraction of Metals

Metals are extracted from concentrated ores using suitable chemical and physical methods depending on their reactivity.
