The mining industry has had disastrous effects on ecosystems of fresh water lakes in Africa and in the seas because of the loss of habitat for marine organisms and biodiversity. As a result, there is a threat to the flora and fauna of the continent. There are also serious physiological and psychological consequences for Africa.

Deforestation due to mining leads to the disintegration of biomes and contributes to the effects of erosion. In situ leach (ISL) mining ISL mining has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock (World Nuclear Association, 2012).

While mines may seem to have smaller effects than other more land-based operations (e.g. agriculture and forestry), mining’s environmental and social effects may extend well beyond the mine site. Many of the mining-related environmental issues arise from waste management such as tailings, leach heap, overburden and waste rock (Holden and Jacobson 2012 ; Ngetich et al. 2019 ; Onifade et al

Cone crushers are compression machines that take in raw materials and reduce them in size by crushing them. A variety of industries rely on these tools, such as the concrete, aggregate, mining, coal, and natural gas industries. Inside the crusher, a piece of steel, known as the mantle, rotates eccentrically.

Impact crusher. Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor.

Hundreds of tons of rock are unearthed, moved, and crushed in mining operations significantly increasing the amount of dust and particulates in the air. In addition, mine tailings, which may contain finely ground and even toxic waste, can become airborne. This air pollution can directly affect human health.

This indicates that attempts to lessen the environmental impact of gold production should focus on these two stages. Mining and comminution are highly dependent on the grade of gold ore, as the lower the grade, the greater the amount that needs to be mined and the more crushing and grinding is required to extract the gold from the ore.
