Mining Methods and Mineral Uses

The video tutorial introduces mining, its importance, and the classification of minerals into metallic, nonmetallic, and power minerals. It explains various mining methods, including surface and subsurface mining, and details techniques like opencast, strip, and alluvial mining. The challenges of underground mining and the process of drilling for oil and gas are also discussed.

What is the primary reason mining is considered a non-renewable industry?

• It does not impact the environment.

• It is a source of renewable energy.

• It is a sustainable practice.

• Extracted minerals cannot be replaced.
