To develop a grip on every topic students must solve intext questions and exercise question of NCERT class 12 chemistry. In this chapter, there are 4 intext questions are given between the chapter and 27 questions are given in the exercise at the end of the chapter. The NCERT Solutions for Class 12 Chemistry chapter 6 General Principles and Processes of Isolation of Elements are prepared by our subject experts to help students in clarifying their doubts.

In NCERT Class 12 Chemistry chapter 6 General Principles and Processes of Isolation of Elements, there are a total of eight sub-topics which covers important concepts of the chapter. After completing this chapter student will be able to explain the terms like ores, minerals, concentration, benefaction, calcination, roasting, refining, etc also students able to understand the principles of oxidation and reduction as applied to the process of extraction, apply the thermodynamic concepts like that of entropy and Gibbs energy of the extraction of Cu, Al, Fe and Zn.

The history of civilization is linked to the use of metals in different ways. Different periods of human civilizations have been named after metals like bronze age, iron age, etc and the extraction of metals brought about several changes in society. So, the Class 12 Chemistry chapter 6 General Principles and Processes of Isolation of Elements is an important chapter from the historical point of view. Aluminum (Al) is the most abundant metal found in the Earth's crust.  Approximately 8.3% by weight. Cleaning of ore of metals by the removal of particles like clay, sand, etc. from the ore is called concentration of ore. This is done in the following steps: Hydraulic washing, Magnetic separation, froth floatation method, Leaching.
