Phase IFoundation

Background

Overview

UPSC focuses on resource optimization, industrial self-reliance, infrastructure development, and environmental sustainability. Coal beneficiation addresses these by improving domestic resource quality, supporting core industries, reducing import dependence, and mitigating pollution from coal transportation.

Coal beneficiation is the process of improving the quality of coal by removing impurities like ash and moisture, typically through washing in facilities known as washeries. This process is crucial for enhancing the calorific value and suitability of coal for various industrial applications, especially steel production, and for reducing environmental impact.
