Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
mining engineer may also be involved with the closure and reclamation of the mine property,although he or she may share those duties with those in the environmental fields. The fields of processing,refining,and fabricating are assigned to metallurgy,although there is often some overlap in the mineral processing area with mining engineering.
Zinc occurs naturally in air, water and soil, but zinc concentrations are rising unnaturally, due to addition of zinc through human activities. Most zinc is added during industrial activities, such as mining, coal and waste combustion and steel processing.
Industrial Process. Mining can be an extremely destructive practice that often has very negative impacts on the surrounding environment. Because the material that is mined for is surrounded by other ore and rock, mining creates large amounts of mineral waste in the form of waste rock and tailings.
