Bauxite Mining in the Boké Region (Western Guinea):

Bauxite mining does not require tunnels as digging gold mining or other mineral ores. However, it still requires heavy digging equipment and generates tremendous dust that pollutes the surrounding areas air. Diagram of bauxite mining and its impact on the study area environment is presented in this section, and also images shows

Bauxite an overview ScienceDirect Topics

Since bauxite occurs naturally at the surface of the Earth’s crust, mining practices tend to be straightforward. Surface pits are opened using explosives to reveal bauxite beds. The bauxite ore is then excavated and loaded into trucks or rail cars for transportation to the converting or processing centre.
