The mining of columbite/tantalite (COLTAN) has a negative effect on the different spheres of the environment notably; hydrosphere, lithosphere, and the atmosphere (Eisler 2004). Just like gold mining, COLTAN extraction involves the breaking of crystallographic bond in the mineral ore to get the products in the pure form.

Coltan / Columbite Mining Method. The method of Coltan mining: hand separation, flotation, chemical or chemical flotation, radioactive, gravity and magnetic separation. Coltan is mined by hand in the Congo. Congo has a group of coltan mined by hand. The hand mining method is to dig basins in streams and scrape mud from the surface.
However, the adoption of the environmental management tools such as Environmental Impact Assessment (EIA), Environmental Impact Statement (EIS), and the harnessing of best practices valorizing local knowledge are still lacking. Thus, the pressure on the environment is still heavy. Industrial mining in Liberia includes gold and iron ore.
Most countries require an environmental impact assessment (EIA) before giving the green light to a mining project. EIA processes provide a valuable opportunity for citizens to participate in decisions about mines. The problem is, project proponents often submit long, complex EIA documents that are incomprehensible to lay people.
