Different types of mining have various impacts on land. For example, strip mining results in the clearing of trees, plants and topsoil [2]. One effect of this type of mining on the environment is the pervasive problem of soil erosion, which in turn leads to the pollution of waterways.. Another destructive type of mining is underground coal mining.

The essentiality of copper for animals was reported in 1928 in a study showing that it is essential for erythropoiesis in rats fed a milk-based diet (Hart et al. 1928). Erythropoiesis was improved when copper sulfide containing ash was added back to the diet (Hart et al. 1928). Reports of copper-deficiency in grazing livestock followed, further substantiating the essentiality of copper (Neal ...
