Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners.

The Environmental Impact of Cobalt . Cobalt is mined through surface and underground mining. Surface mining is the process that involves removing the top layer of soil or rock to access minerals or metals, while underground mining involves digging tunnels and shafts to access minerals or metals located deeper below the surface.

Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.

Alkali basalt is a fine-grained dark color volcanic rock composed of phenocrysts of olivine, titanium rich and iron oxides (Fig. 4.40). Alkali basalt is relatively poor in silica and rich in sodium. It is silica unsaturated and contains feldspathoids (nepheline, leucite), alkali feldspar and phlogopite (magnesium mica) in the groundmass.
