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 effect on the quality of human health and biodiversity. Some mining methods may have such significant environmental and public health effects that mining compani
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 effect on the quality of human health and biodiversity. Some mining methods may have such significant environmental and public health effects that mining companies in some countries are required to follow strict environmental and rehabilitation codes to ensure that the mined area returns to its original state.

The main sources of emissions during both the construction and operation phases include the products of combustion such as nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide and fugitive dust from the operation of equipment. The main sources of combustion-related emissions during both the construction and operation phases are related to diesel generators, fuel-oil boilers, and from on-site road traffic. Fugitive dust emissions can occur during land clearing, ground excavation, and from equipment traffic on site. Potential sources of fugitive dust
The main sources of emissions during both the construction and operation phases include the products of combustion such as nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide and fugitive dust from the operation of equipment. The main sources of combustion-related emissions during both the construction and operation phases are related to diesel generators, fuel-oil boilers, and from on-site road traffic. Fugitive dust emissions can occur during land clearing, ground excavation, and from equipment traffic on site. Potential sources of fugitive dust during operation include ore loading and unloading, ore crushing, stockpile erosion, and dust from conveyor systems around the site. Fugitive dust emissions are proportional to the disturbed land area and the level of activity and vary substantially from day to day with varying meteorological conditions. The major effects of industrial air pollution on wildlife include direct mortality, debilitating industrial-related injury and disease, and physiological and psychological stress Acid is created when water and oxygen interact with sulphur bearing minerals and chemicals in rocks. Sulphuric acid is the most common chemical reaction that results from mining activities as the beneficiationprocess requires dissolving the minerals surrounding the ore, which releases metals and chemicals previously bound up in the rock into nearby streams, freshwater bodies, and the atmosphere... Acid may be generated under natural conditions prior to any disturbance, but mining activities typically magnify the amount of acid produced, thereby causing an inequality in the surrounding environment. This process is referred to as Acid Mine Drainage (AMD). Acid produced from AMD causes health hazards to many fish and aquatic organisms as well as land animals who drink from contaminated water sources. Many metals become mobile as water bec
