Open-Pit Mining: A Comprehensive Guide

Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.

Reclamation of Degraded Landscapes due to Opencast Mining

The most common surface mining methods such as strip mining, open pit mining, opencast mining and quarrying start from the earth's surface and keep exposure to the surface during the extraction period. Disruption of the surface significantly affects the soil, fauna, flora and surface water, thereby influencing all types of land use.
