Respuesta :
The difference is where the material came from. Spoils come from overburden and is discarded as waste, whereas, tailings come from left over dredging of steam beds that are discarded as waste as well.
Spoils and tailings are the runoffs and wastes disposed of from a mining field. Tailings come from the waste after extraction, and spoil is a rejected waste.
What are spoils and tailings?
Spoils are the wastes and debris that come from mining. They get accumulated during the excavation or when the foundation is dug for mining purposes. The waste contains chemical wastes, rocks, and soil.
On the other hand, tailing is residual waste formed as a result of the ore extraction and gets disposed of on the land or even in the water bodies. They may contain chemicals and are a good source of metals.
The minings and tailings must be disposed of safely as they can lead to environmental issues like landslides, land degradation, soil pollution, water pollution, etc.
Therefore, the tailings and spoil are the mining waste that differs in the source.
